Hi
First of all try to reinstall Microsoft ActiveSync, than in the ActiveSync options, in your device, be sure that in "Connections..." setting "Synchronize all PC by this connection" is checked and below "USB" showed!
Otherwise, if your device, when connected to the PC, also doesn't charge (if you have this option enebled on your PDA!) there is some problem on your PC settings concerning the USB! Try to connect to someother PC to test it!
Ciao

thx...

hello there, first n foremost thanks for your input!
Before trying out your possible solution i tried to connect and for some reason i was able to connect via the device today...??!!
i really dont know why, but will try your soln if this situation reocurrs.
NB: this happenned to me twice in the last 3-4 months, n i never figured out the cause ??
any other advice or ideas gratefully accepted.;

its probably the same as me and loads of other people - the pins have bent on your usb connector - probably caused by using non standard chargers and usb leads. Its been widely reported. The non-standard leads have too much space around them when plugged in and wiggle causing the connector on the tytn II to bend. Try using the lead which came in the box and see if it helps. and try using the charger that came with it too.

Can bent pins be fixed?
Hello -- I'm one of those people with a non-recognition problem. Is it possible to fix the bent pins? My problem seems to have begun around the time I lost my original USB cable. Now, all the cables I have -- ones that have been specifically sold to work with my HTC Tilt -- have the symmetrical, sort-of-trapezoidal mini-usb connection, rather than the rectangle-with-one-corner-cut-off shape of the original cable. I should say these cables do charge my device, but none of my computers recognizes it as a USB device.
Help?
Thank you,
J. Georgia

bent pins continued
I should add that the charging cable that originally came with my phone has the same connector shape, so I'm not sure what's going on.

USB Device not recognised
This is known to happen at times win Windows, and not just for the TYTN2 but a myriad of devices.
The fastest fix for this:
Reboot ur PC/ Laptop.
If this Doesn't help - Then add in a reboot for the TYTN 2 also.
The problem will go away for some time.
I know its annoying, but this is way faster than troubleshooting for contacting MicroShaft Support.

Unfortunately this is no soution for me. I seem to have this problem as well, since about two weeks.
I use two notebooks (Dell & Acer) and both do not show any activity when connecting my Kaiser to the original USB cable. The device is not even switched on when I connect it, nor does this happen when I connect it to the (original) cable in my car, which did work before.
Charging works fine, both in the car and when connected to both notebooks, but no Sync at all.
I have tried another USB-cable with the same result, so I suspect some hardware-problem causing me to be unable to copy files between my notebook and my phone and worse, rendering me unable to flash a new ROM onto it.
Who knows what to do next?

I am mystified, too. USB Charging and audio connections work. I have rebooted my computer and done a soft reset on my phone several times, to no effect. I uninstalled and reinstalled Windows Mobile Device Center. Still nothing at all via USB. Once, yesterday, I somehow got a Bluetooth connection long enough to sync, but haven't been able to since then. Even then, Windows Media and AudibleManager couldn't see the phone. The really weird thing is, I can see the phone connection in my Bluetooth manager, but even with all the proper boxes checked, I can't sync. When I try from my device, I get an empty progress box which disappears after a fraction of a second. When I try from my computer, it says the device is not connected, but doesn't give me any option to connect.
Would a hard reset help?
If so, would returning an unlocked AT&T Tilt to factory defaults lock it back up? And what do I do if it does?
Please help!

I have had similar problems with my touch pro in the past, even bluetooth internet sharing eventually gave up the ghost.
I tried a myriad of leads and then eventually reinstalled active sync- which did the trick.

I've had the same problem with my first Tilt. There's multiple threads that detail this known problem. Some seem to be due to bent pins, some are general hardware failures (possibly the USB controller). There are some HardSPL images out there that have a "force usb" option enabled. This never worked for me, but it might be worth a shot for you.
...a word of warning....
If you end up reflashing your phone (via MicroSD) and the flash goes bad, you may be stuck, as many of the solutions for repairing a bad flash require you to USB sync. My first Tilt was a victim of this after a bad stock ROM flash that left my device without audio, and unable to flash via MicroSD.

replace usb board
you need to replace your usb board. It will run you less than $10 if you do it yourself. you can get the board on ebay

really? 4 years later?

[Q]Error on my Diamonds USB slot?

Hi!
I've searched and fund some stuff similar to my problem but no solution, so I'm trying again.
The problem started when I updated to ROM v 1.93.
Whenever I connect my device to the PC (I'm running Vista) through USB connection I get the quistion on my phone if I wanna use it in Active Sync mode or as a disk. So far so good. No matter which alternative I choose i takes only a few seconds for me to get the same dialogue on my phone again and again and again and I cannot acces the phone from my PC.
My first thought was that the usb slot in the phone must be broken but I can charge the phone if I plug inte wall but not via the PC.
Is this a software prob. or something else and can this be fixed or do I have the go back to the store with the phone?
I would really appreciate some creative answers to this.

Do you have any other miniUSB cables to test with? That would be my first move.

Disconnect device and delete the partnership between PC and Diamond. Try reconnecting. If no joy, delete partnership and delete Windows Mobile Adapter from Device Manager.

horrible problems with my USB cable and diamond

hi,
I think my cable or port on my diamond is a little screwed, active sync stopped working just a week after I got the phone.
I posted the problem here:
http://social.microsoft.com/Forums/...c502e361-e0e4-4d26-9ead-7f2680ff160e/?lc=1033
I got Nothing so far. I did all the active sync troubleshooting I could when I noticed that when I charged my phone, the dialog to choose active sync or disk driver shows up!!? As if i plugged it into a pc, also I do plug is into any ANY pc as a Disk Drive, it doesn't work at all.
IOW.. when I connect my phone to *charge* a dialog shows up asking me whether I want Active Sync or Disk Drive as if i connected it to my PC. Nothing happens after that, and it will not connect to active sync or disk drive to ANY Pc (tried multiple pcs).
What could the problem be? Should I try htc tech support?
Please help, this phone is only a month old!
Thanks so much
Gideon

Ok.....I'm not sure what you're trying to say. What's the message you get on your screen when you connect your phone to the pc via activesync?

I'm sorry, I was freaking out just a little while writing that. I rephrased some of it.
I get the same dialog "Active Sync or Disk Drive" when I connect it to my PC, but nothing happens after that, and it doesn't work on any pc at all. And its driving me nuts, to send a file to my phone from my desktop(my main computer) I have to connect it to my laptop via a lan wire, then send the file over there, and send it from the laptop via WiFi to the phone! ! =X
Oh btw, I've also tried other mini USB cables. Same thing.
Thanks so much
Gideon

What version of activesync are you running? Download the latest version from here. Activesync runs on all OS versions from Win 2000 SP4 upto XP SP3. If you have Vista installed on your machine try this link.
Would you be able to paste a screen shot of the error message and the dialog box?

I use the latest 4.5, but that does'nt seem to be the problem.
It doesn't work as a Disk Drive on ANY computer? There isn't any message or error, on the phone I get the dialog "Connect To Pc" dialog, I choose DISK DRIVE but it doesn'nt work, not on MY pc not on ANY PC!! ='( And just nothing happens.
I've given up on active sync, i've read every post here on xda and elsewhere, I simple can't get it working, I don't have active sync on my pc now. On my laptop with *Vista* however, the windows mobile device center manages to connect and sync with my phone via *bluetooth* only
Thanks so much.

Take out the memory card from your phone before connecting it to activesync and try again. Tell me what happens.

You cant take out the diamond's memory, it's build in internal memory m8, not like the touch pro's microsd or anything so he wouldnt be able to try/ do that
I've had active sync problems as well, I normally find it's simply the sh*tti microsoft OS's/ programme's problem & if you re-install or update the active sync prog or windows mobile centre if your using vista, it then see's the diamond again no problems & let's you then set it up correctly, so I'd try all that 1st before you go phoning htc or your carrier to complain m8

Had the exact same problem with my Diamond.
The fix was; return to reseller/change of mainboard in the phone.
A known problem with some Diamonds according to the technician who did the repair.

Humm, I ran into a similar problem with my Diamond when I bought it less then a week ago. Nothing happened when I connected the with the bundled cable though it did work at first. So I took a normal one (from the ps3 controller to be exact) and it worked fine, I've not messed with the bundled cable since.

Solution for me
Hi,
I had this exact problem, wouldn't sync with any PC/laptop tried all the active sync's and tried all the options in there. Also tried multiple cables and still no joy.
This needs sending to HTC for them to fix. Go here:
http://service.europe.htc.com/Tracking.aspx and book it in for repair.
This is a known fault that happens with these phones and they fix it without charge.
However, don't be like me and try and fix it yourself, otherwise you'll be £70 lighter. I thought one of the mini usb prongs wasn't making contact (as it still charged ok) and after messing about the little plastic in the mini usb port came out. HTC said I damaged it and so had to pay for repair. If I had just left it alone they would have fixed it.
Also when they fix it they should load on for you Rom 1.93 which I'm finding is making the phone so much better. Its worth the money I've had to pay just for that TBO its soooo much slicker now.
The reason why this fault has developed (that some people have said) is that some car chargers are delivering too much power for the port especially when plugged into the car charger and then starting your car. I've seen that the normal charger delivers 5 volts and 1 amp so i've bought a car charger that does the same volts/amps from here:
http://www.dealextreme.com/details.dx/sku.688~r.53733725
I've used it once and it hasn't fried my Diamond yet. (it did however come up asking to activesync or usb drive when it was plugged in unlike the standard charger which doesn't prompt at all)
You also buy the official car charger which is more £££
You'll be without your phone for a week at least and you'll have to install your apps on it again.
Hope that helps

Hi,
I know this is an old thread, but thought i would add what i found as google brings this thread up when you search for this issue. I read through the solutions and through i would remove and reinstall mobile device centre. I found it had gone! Dont know why. I didnt uninstall it and havent ran a system restore etc. Anyway i reinstalled it and problem solved I think Bluetooth might have also been interfering.

USB Connection

Hey there
My phone has been connecting perfectly fine since I got it about a year ago right up to a couple of days ago.
I've just changed my contract and wanted to unlock the phone. However, before I could even go about doing I discovered that my computer (Vista 32bit) was no longer recognising the phone.
When I plug it in it does charge but the computer gives no reaction. Even when I put the Kaiser into bootloader it still says Serial instead of USB.
I have tried disabling enhanced network functionalities on the phone, I have reinstalled Windows Mobile Device Center, I have hard reset the Kaiser, I have used multiple USB cables and multiple USB ports (all of which work with other devices).
As a result of the hard reset I have now lost the majority of my data. It's all backed up on my computer but this isn't much use when it refuses to recognise the phone!
What can I do to fix this?
Any help would be very gratefully accepted!
Cheers
McAsh

I would try it on a friends XP machine or a friends Vista machine. Try to narrow down if it is the phone or your PC , and then proceed from there.

HI!
I have the same right problem!
The only way i can do activesync is connecting the phone in activesync by bluetooth and the sincronization is fine, but i need to put HardSPL in it and i need that it can be recognized by USB connection and my Kaiser is only charging from USB, it is not being detected by the computer.
PLEASE HELP!!!
Thanks!

had same problem
no one help, I started a thread and no replies
till today I plugged my kaiser to usb and computer recognized and synced
I was using bluetooth to sync for a couple of months
I really didn't do anything to fix this first I thought it was usb connection but it wasn't because I was able to put new rom thru the usb so connetctoin was there when the phone is in the hard reset mode. WEIRD ha

mostly these things comes down to 3 reasons
1. defect usb connector in the ppc
2. corrupt activesync install full uninstall and clearing registry of the pc should fix that
3. issue with usb port chipset drivers for on the pc

Also having a similar problem.
My computer recognizes my Kaiser as "HTC USB Sync" in the Device manager but nothing more happends. Could it yet be the phone USB connector that is broken? Also I was able to flash the rom yesterday (from bootloader).
When plugged in, my phone totally freezes and becomes available again the moment I unplug it and by then starts "connecting to host".
If I uncheck the "allow usb connections" box in WMDC the phone is workable but very juddery.
Have tried to completely uninstall WMDC and reinstall it again with no success whatsoever.
Any tips or is my only solution to buy a bluetooth-dongle?

The solution for mine is really the repair center unfortunately!
It really seems to be a hardware problem in the USB connector, i can't even change a firmware, the pda simple isn't recognized by the computer :S
Anyway thanks for the help!
Regards!

I am also having the same problem!! My question is how do you use bluetooth to sync with the activesync(not too computer saavy!!)

Check the usb connection on the phone. It may have a contact pushed over or broken

I got the same sympton.
I can get my phone to sync by pushing the USB connector harder towards the phone. Yes, it is connected already, and it is not lose, and the PC recognise it as HTC device in Device Manager, but it is just not detected by the (Vista) Windows Mobile Device Center
If I keep pushing the usb connector in (towards the phone), then it would get detected and start syncing. If I relax my hand and stop pushing, the active sync connection will drop immediately (still detected as HTC USB device in Device manager though).
Therefore, I have to keep pushing it in to have a successful sync. I don't dare to flash the firmware anymore... :-(
P.S. I am using the official O2 WM6.1 firmware, and using the original USB sync cable. I noticed that the original USB cable's connector head is a bit longer than ALL my other USB cable's connector head (the mini USB head).
Originally I didn't need to do the push in for the phone to get recongised, so I figure it is some sort of wear and tear on the phone's connector... :-( This does put me off in purchasing another HTC phone, because the new one is likely to suffer from the same wear and tear...
btw, before the connector got that bad, when it was connected but not synchronising, I could get it to sync just by launching Windows mobile device center (which is a different program than sync center in vista); and of course, when it was all brand new, I just need to connect the phone to the PC via the USB cable, and everything happened automatically...

I am trying to flash my first rom and the computer would not detect the phone. Took a look at the female mini USB socket on the phone and the 3rd pin out of 5 was much lower. Took a tiny screw driver and pushed it up and I got success. Its a little sensitive but if you dont touch the phone it will work fine.
Good luck
Jason

HI gdarrenc!
The way to sync it via Bluetooth is when you open the activesync in your pda, in the options menu you have the option to sync via bluetooth
Regards!

possible solution if feeling brave
My hotsync failed a few days ago, did the usual searches and posting on here with no joy and then did a google search for a picture of the mini usbport.
on inspection of mine in comparison i noticed the two leftmost pins were down to the point they were in the sticky out black bit so with a pair of my wifes best precision tweazers i flexed the black bit down slightly and slid the tweazers to the right lifting them up slightly. as soon as retested it is now working again.
NOTE BE VERY VERY GENTLE WHEN DOING THIS - DO NOT USE ANY FORCE
my guess is this is due to an ill fitting usb cable as mine had a certain degree of up and down flex when connected.
hope this helps someone.

I am also having issues with pc-htc connection.
But, this happened when I pulled the usb out of the phone with my leg.
Now, I squezzed usb head a little, and it works fine.

usb connection problem

hey guys i have a usb connection problem with my galaxy note.. whenever i connect my phone to my pc the usb connection icon doesnt appear neither any message shows up on the pc, the only thing it does is charge the phone , i even used differnt usb , tried reflashing the rom , thoough im using a custom rom , but no success, but there is one thing when i phone is connected to the pc and during that interval i restart the phone a message appears on the pc at the boot screen ...unrecocnized device connected, as soon as phone proceeds it too disappears.....if you guys know anything about this kindly help me out.....i have to pull my sd card every time i need to put something in my phone

It's possibly due to condensation on micro USB port of your mobile. Try cleaning it with rubbing alcohol and keeping your phone under the sun or in dehumidifier.

abhjit could be right but if you check on all custom rom threads people are having problems with usb connection
the latest ics releases of samsung ( even JB i believe, not sure tho ) have this problem plus full root problem,

Just clean it as is. You might be able to see the problem, but you will need a good magnifying glass or loop to see it.
I took some photos I found on the web of a dirty port and colored in the contamination I found on mine.

I have the exact same problem. My device doesn't get recognised by windows 7. It doesn't ask me if I want to use the phone as a pendrive. When plugged in, it only charges the phone. Sometimes the phone does not even realise that it has been plugged in at all. I dont think that its a problem with the pins because I have tried using an OTG and been able to connect to an external hard drive and copy files. Also I have been able to use PC Odin and flash a stock rom using a usb cable. This makes me think that all the pins are fine, and that its a software problem. Something has got glitched and not getting un-glitched lol!
Current Rom is the here

one thing you can try.. is to completely uninstall KIES off and remove all samsung usb drivers off your computer. When I say completely uninstall Kies, I mean totally removing it, from your system registry files and including Samsung folders that you can find in Program files or in program files x86..
After that, restart your computer and reinstall Kies and/or all samsung adb /usb drivers again.
Don't forget as well to plug your usb cable at the back of your PC since mostly USB ports coming from the back of it has strong usb signals than the ones at the front.
Hope this helps.
Don't forget to hit me up a 'Thank' if I've helped you some way or the other.
Cheers!

isolate the issue first...get another usb cable, and if you have another computer (aside from the one your normally using at), try to plug your phone on that computer and see if that pc will detect your phone.
If not still, then that's the time you can already consider that your phone might be the one having the issue.

Well I guess, that would prove the point that it could be your phone that might be having the issue bud. After all, you tried different options already but still came up with the same issue.
I'd suggest you may need to take your phone to SSC and have them check it.

thank you all for your support friends ...i have been able to repair it...i opened the cell phone thoroughly cleaned the usb module and reattached the connection cables after detaching and voila...thank God... :laugh:
