Can someone explain the USB sync/charge interface?

Ok, so hoepfully someone can clear this up as I don't yet have my Kaiser (tilt) and am trying to get some accessories.
I previously had a PPC-6700 which synced and charged via a standard mini-USB jack.
I then upgraded to the PPC-6800 which I only had for about a week (had to give it back to my work). With that device there was a different type of usb jack on it that seems to be what the Kaiser also has. Can someone tell me what this is called?
From my recollection however, this slightly different jack would also accept the typical mini-usb plug as i can remember using my PPC-6700 wall charger on it.
So can you use standard USB to mini-USB plugs to interface the Kaiser with either a PC for sync/charge or to a wall-charger? What is the new interface called and what is the point of it?
thanks much!

I may have actually answerd my own question as I have found (I think) the name for this new interface... EXTUSBTM ? Is this correct. And the point is to interface the charger/sync and audio headset together?
If this is all it does then I should be fine using all my old mini-usb plugs for data interface/charging, right?
thx!

Yes, you can use a standard 5 pin mini USB cable. The port is HTC's 11 pin combination sync/charge/audio port. Both their plug and the standard 5 pin mini USB plugs fit and work.

Wikipedia (for once!) isn't too big on details here: http://en.wikipedia.org/wiki/HTC_ExtUSB
But basically, it's got 11 pins to handle audio, power and syncing.

Have a look here for pinouts etc.

Activate Navi Panel without Car Kit, with simple mod

Hi
I don't know if people realise this but you can modify a generic car charger to automaticlly activate the Navi Panel mode so you don't need to buy the SU400 kit.
You will need a car charger that is capable of suppying 1 amp, to enable fast charging. ( Use an app called Spoon Charge to check) or disassemble the USB Micro A plug and ensure Data- and Data + are soldered together. DO NOT solder Data - and Data + togehter if not already done so this means the device is not capable of supplying 1amp.
If so you should have a unused pin ( this is called the ID pin) solder this along with Data + and Data - to OV.
When the charger is connected it will launch Navi Panle if enabled and turn on bluetooth and pair to a set device.
I will take a pic of the modded plug and post it up. In theory I would assume the same mechanism is used on more than this device.

OMG LEGEND bro. lol. Finally someone figured out HOW to do this so you don't have to buy that overpriced HD2 carkit. Thanks. Mod's this should be a sticky.

mods seriously this should be front page news

Are you sure, that this will work? Did you tried it yourself? Cause my CU-S400 is also activaiting the Navipanel even if i don't have plugged in the Charger! So I think that it hasn't anything to do with the mAh-size of the charging unit....

You're right.
Right connections for recognition Car Kit Mode :

Nxt things i will work on..

1) a 3.5 mm fm transmitter which will work on any 3.5 mm jacked device.
It should be purely analog. And contains a in built li- ion battery. Draws audio from 3.5 mm jack and send it on air in the tuned frequency.
2) a docking station with audio playback and usb charging. ( trying to figure out the methods through htc music head phone controls volume, next, previous, and stop/ play music) . So that i can add an ir remote too..
Post ur suggestions.
Regards
Showly.
send from my hd2 @ miui 1.12.2

This should be in Your speciffic device forum.
You want a $10 FM transmitter from radio shack and a music dock.

Nop. Thatz not a device specific one. But the thing is in case of dock, i have only hd2 with me for checking. Thats why i go for htc. If some 1 can provide me the headphone diagrams of other phones, it will help me 2 develop a generic dock.
And about readymade tx and dock, nop i am not going 2 buy them. I am going 2 make them. Thatz it.

this one is what i am planning to build, removing the mic , then adding a low ohms resistor in series to the i/p, and then connect it to the 3.5 mm male pin(for inserting into 3.5mm jack). adding a small 3.5 v li-ion battery,and a usb or similar charging port. and enclose it in a small box..
for now its a mono tx. but you can bulid a sterio one with ba1404 ic, but i cant get one here.. so i went for mono. but i will give u the circuit for sterio one
here is it

Problem - My headphones (USB C) discharge my smartphone

Hi all,
I recently bought a new headset (Sennheiser PXC 550-II), and I want to use it with USB C on my smartphone. However, when I plug it in, the battery of my Samsung Galaxy S10 drains to charge the headphones. How can I disable USB discharging (Android 11, root OK) ?
Thanks for your help !

I think the USB cable is only for charging the headphones.
You should user the studio cable to get it audio connected to your S10. Fortunately it still has the headphones jack.

Thank you for your interest in my problem.
Following some comments found and in order to want to disable the + 5V pinout of the USB socket, I also tried the cable "micro-cable male C to USB-A female OTG" destined for an external DAC, but the same problem happened.

After hours of research, no solutions finded.
So, I will stay in jack, because even if I lose the audio controls (and a little background noise that I don't have in USB ), my smartphone battery will be preserved.
I compensate with a 3.5 --> 2.5 jack cable from JBL with microphone and 1 button for "BL E35 / E45 / E55 / E65 / C45".

Accessories Ready For + Lap Dock HP X3 Elite

Hello, everyone, I want to share my experience with HP X3 Elite Lap Dock and Ready For.
Pros:
- works out of the box
- quality of keyboard is excellent, screen is also good
- size -> I was looking for something small and ultraportable
- price, I bought new for about 350pln (~80 Euro), USB C <-> USB C cable, 45W charger, USB C otg cable included
Cons:
- Audio is not working, you have to switch to phone speaker, Bluetooth or usb c headset
- touchpad is not very comfortable at this moment. Tapping is the only way how you can left click, buttons in touchpad are not working. (propably update should fix it)
- firmware update is only possible through HP Elite X3 smartphone with windows mobile (one of my friend have one, I should get this phone in few days)
For me its the perfect solution to work with termux and debian arm64
Overall, I can realyy recommend working with this lap dock. Even if not for motorola, its cheap and good as second screen to my laptop (linux, windows tested without any issue)
Cheers
PS sorry for picture quality, I only have my old LG G2 to take a picture
