Weird I got one off eBay from Hong Kong and it works without Modding. Can open files off a USB stick. Got it for £1

Anyone knows how the Galaxy determines to be in home or car dock?
ALexander
Can you please give me some advice on how connect this connector? B -> E?
Is it possible to add USB charging cable to USB-host cable? I want to use mouse\keyboard\flash and charge device in the same time.
I also interested how to add power to USB-host cable for devices "High-power device connected".
thats excactly my question:
is it possible to use otg cable with a trackball or mouse and at same time charge the S2?
give power to usb mouse and charge S2 over a charger!?
it is not possible. usb host can be used one way not two ways.

Thanks a lot for the link. However, I'm still not sure how to actually do it. It seems to be a matter of connecting the right resistors to the USB connector, like in the USB jig, but i have no idea what values to use. I think I saw a table with resistor values somewhere... must search

It is under section 6 in that document called "ASA", and i don't think it is a simple resistor but won't be very complicated also.
So would be cool if we can get some help and figure it out.
RID_RESERVED_1, /* 0 1 1 1 0 28.7K Reserved Accessory #1 */
RID_RESERVED_2, /* 0 1 1 1 1 34K Reserved Accessory #2 */
RID_RESERVED_3, /* 1 0 0 0 0 40.2K Reserved Accessory #3 */
RID_RESERVED_4, /* 1 0 0 0 1 49.9K Reserved Accessory #4 */
RID_RESERVED_5, /* 1 0 0 1 0 64.9K Reserved Accessory #5 */
RID_AUD_DEV_TY_2, /* 1 0 0 1 1 80.07K Audio Device Type 2 */
RID_PHONE_PWD_DEV, /* 1 0 1 0 0 102K Phone Powered Device */
RID_TTY_CONVERTER, /* 1 0 1 0 1 121K TTY Converter */
RID_UART_CABLE, /* 1 0 1 1 0 150K UART Cable */
If it's not a resistor, then what do you suggest?
This thread seems to be the best piece of information on resistors, but none of them seems to be what we want.

I've been digging a bit more in the datasheet, and the tables in chapter 6.5 and 5.3 gives us all we need. It seems to be nothing more than a 119 to 132 kΩ resistor and the phone will charge while still providing OTG functionality. I think i have a spare micro USB connector in a drawer somewhere, so i'll try this out ASAP

The PDF says:
3) Nominal values for these resistors are RID_A = 124k, RID_B = 68k and RID_C = 36.5k.
The Fun with resistors thread says:
Code:RID_RESERVED_1, /* 0 1 1 1 0 28.7K Reserved Accessory #1 */ RID_RESERVED_2, /* 0 1 1 1 1 34K Reserved Accessory #2 */ RID_RESERVED_3, /* 1 0 0 0 0 40.2K Reserved Accessory #3 */ RID_RESERVED_4, /* 1 0 0 0 1 49.9K Reserved Accessory #4 */ RID_RESERVED_5, /* 1 0 0 1 0 64.9K Reserved Accessory #5 */ RID_AUD_DEV_TY_2, /* 1 0 0 1 1 80.07K Audio Device Type 2 */ RID_PHONE_PWD_DEV, /* 1 0 1 0 0 102K Phone Powered Device */ RID_TTY_CONVERTER, /* 1 0 1 0 1 121K TTY Converter */ RID_UART_CABLE, /* 1 0 1 1 0 150K UART Cable */
It's pretty close, 121 vs 124 k, 64.9 vs 68 and 34 k vs 36.5 k, and actually quite weird the ACA modes arent listened in the source. Is this wrong? Is the 124 k resistor going to trigger TTY converter mode, whatever that is, instead? I guess i can find the answers in the kernel logs when i try it out.
Anyone having this problem. When i connect mouse or keyboard it is not recognized at all, and everything works fine with usb drives. Even tried with self powered usb hub so power is not an issue.
