[Q] Galaxy Tab USB host problem with OTG cable - Galaxy Tab Q&A, Help & Troubleshooting

I am using great AOKP SGT7 Milestone #6 on my GT-P1000.
When I started to test USB host. I can get unstable connect sometimes by original stock charger cable + Y cable. It will not stay long to work, but works for USB host mode! I never get devices by Samsung OTG connector (S-K03). I take pictures for pin-out. It has 1(USB Black),3(USB Green),4(USB White),6 (USB red),13_20k_15 only. I dont want to break stock charger cable, but I take a look on pin-out. It has 3,4,7,8,15,16,30. Weird for charge, Isnt it?
Is there any modification to let it work? At least make it as a charger cable?

USB 2.0 A Female to Micro-B Male Adapter cable supported in Milestone?

Hi,
I want to connect my pendrive/usb mouse to my milestone via USB 2.0 A Female to Micro-B Male Adapter cable. but milestone is not able to connect it. nothing happens when i connect the cable to it in its microusb port.
I tried the same in Samsung galaxy SII (unrooted) and it worked well.
I am using [ROM] CyanogenMod 7.1.5 (Android 2.3.7).
I want to know whether the milestone lacks some hardware capabilities or it depends upon ROM?
Use sixaxis men!!!
Wow! mmm.... i dont think that was possible but You could try SIXAXIS to connect a joystick at least. So you can use it like a mouse or any you want without any cables. (Sorry. My english is not so good).
IIRC mounting a usb flash drive should work but only if you plug it in before you turn on your phone.
ie turn off phone, insert OTG usb adapter, insert thumb drive, turn on phone.
But if you remove it after, you will have to repeat the process. Search the dev forum.
USB OTG supported?
I thought USB OTG was not supported on this phone. Does it really work?
IIRC, I think some work was done to try to compile a kernel module to enable support, but it stalled out when they realized there was voltage issues.

USB OTG?

i recently bought a cheap USB On-The-Go cable for the Razr hoping to be able to use my droid 4 with the DSLR controller app https://play.google.com/store/apps/details?id=eu.chainfire.dslrcontroller&hl=en but i am having no luck. i'm on stock w/ root, recently did the 219 update with no change. problem is i have no solid means of troubleshooting. i have a touchpad with cm9, droid 1, droid 2, and my droid 4, but i cannot get the cable to work with any of them even for mounting a usb drive. but i'm also having trouble finding solid info on if it should work with any of them.
has anyone had any luck using usb otg with the D4?
Sent from my DROID4 using XDA
I've gotten it working with a cheap Staples USB hub, a USB Y cable (2 male USB one end, 1 male microUSB on the other end for the hub), and a USB charging brick, the USB OTG cable itself. From what I've put together, it's sensitive to where it gets power from. That's why I had trouble with it at first.
Long story short, USB OTG does work on the D4 stock rom, updated and bone stock

Thanks. i actually was fooling around with my touchpad last night and found out it needs external power as well. so with a y-cable from a seagate portable harddrive, i was able to test that the OTG cable i have is indeed working. however, i could not get my D4 to work using extra power from my PC, but I picked up a kodak power brick today and its charging, so here's hoping that works.
actually nevermind, after playing around with a hub and a usb stick, it decided to work with my PC supplying extra power. after that, DSLR controller worked as long as there was extra power supplied. i imagine the battery pack i picked up should work quite nicely. now to go take HDR photos of the entire world! bwhahaha
Glad you got it working. From my reading, the thing to do is get power on the +5v rail of the micro-usb 'input' port, that will allow power to flow from the USB hubs power brick, thru the hub, up to the phone. Can't help you with that however, it's a bit beyond me.

Cannot get Nook Color to charge while in USB host

Alright so i bought a usb powered hub, a usb OTG cable, and a usb DAC. I can get the usb DAC working fine by hooking everything up but i cannot get the Nook to charge while in USB host mode. Is this a problem with the settings on the Nook or the USB hub i bought? Also is there any way to charge the nook at 2A while in USB host? I assume this would require a custom cable but i have found very limited information on the internet.

I could be wrong or downright delusional, but I didn't think you could (or worse yet, could cause damage if you tried).

MHL adapter for M8

Does anybody know of a working MHL adapter with at least a 12" USB cable?
I tried these and they do not work (work probably 1 out of 20 times if you keep plugging/unplugging)

I have an old samsung (link below) which works but the USB cable is very short

Is the Skiva MHL Micro USB to male HDMI cable (6.5 feet) for Samsung Galaxy S3 (SIII LTE i9300 L710 i747... the one that works with your M8?
I really want to get one that will work.

No, only the old Samsung one works consistently which has the short usb cAble.
I bought this one: http://www.ebay.co.uk/itm/171391851548
works perfectly as I think most will.
It's all down to the sequence you plug the cables in.
Power>Phone>HDMI
Cant remember the correct sequence but try it out.
COPIED FROM AMAZON AD.
1. connect the charger to the adapter cable and power supply
2. connect the adapter cable to the HDTV device
3. connect the Smartphone to the adapter cable

I tried allcombinations before posting and none works consistently with the 2 cables I bought .
With the old Samsung adapter, it doesn't matter which order you plug in phone, power and hdmi.
I don't think all cables/adapters (advertised as 5 pin) are same. It cut open the usb part from the working Samsung adapter and it has 7 wires.
The other non working ones have 5.
If anyone is interested to know, this one works for me most of the time. Doesn't matter which order I plug it in (I usually plug the phone last though)

Its 3m in length and requires external power to work. It charges the phone although slower than MHL drains, i.e. your phone will still be discharging while connected via MHL but at a much slower rate.

[Q] I9305 Usb host mode and charging at the same time

Hello!
Today I (Finally) received my USB OTG Y cable! I have the Samsung Galaxy S3 4G (I9305) and i bought the cable because the ebay site said it was for s3. I was really happy when i got it and plugged my usb memory stick into it. It all worked good. Then I plugged in the charger (to the female micro usb) and it didnt start charging. I wasn't happy anymore. Then i started to researh a little. I found out that my phone doesnt support USB host mode and charging at the same time ( ). So im just asking, is there a way to make my phone charge when i use the OTG cable without any hardware modifying? Can I just likes install a custom kernel that supports OTg charging? Or just make my phone think its docced when i use that cable (I thought that may work)?
Btw im running android 4.4.4 stock rom and stock kernel. Thanks for any help.
And here is a picture of the cable. Down there ⬇
