How to enable USB for android on mini6410?

Hi,
In order to use adb for android, I compiled the android linux kernel with
"S3C USB OTG Host support". after boot with this kernel, we can get
following msg from dmesg:

<5>usbmon: debugfs is not available
<6>s3c_otghcd s3c_otghcd: S3C OTGHCD
<5>UBI: background thread "ubi_bgt0d" started, PID 394
<6>s3c_otghcd s3c_otghcd: new USB bus registered, assigned bus number 1
<6>s3c_otghcd s3c_otghcd: irq 90, io mem 0x7c000000
<6>usb usb1: configuration #1 chosen from 1 choice
<6>hub 1-0:1.0: USB hub found
<6>hub 1-0:1.0: 1 port detected

But when I try to lsusb from Host PC linux, there is no USB device is
attached. How could I make it work?

further more, I also tested with another USB port by plugging & unplugging
a Bluetooth dongle ( with HCI USB driver built into kernel), there is no
message available from dmesg. So How could I enable that USB port?

Thanks in advance.

Hi Pulq,

Were you able to get the mini usb functional uunder Android? I am trying to
do the same but with not much success for now.

Thanks.

I have the same problem.  i can't use adb from Android.  When i connect the
board to PC, it is not detected as usb device.

Can somebody help please !!

same problem!
i found that this problem appears every time i modify the kernel.
for example default kernel has no USB detection problem, but if i change
the default config using make menuconfig, then USB auto detection disabled.
i am sure that config file modification is the root of this malfunction. i
tried to conclude every config that a USB interface need but the problem
not be solved. tomorrow i will take another try with other configs and let
you know.

Have you done a diff on your default kernel config file and the modified
one to be sure that you have only changed one thing?

meld seems to be a useful tool for this.

Then manually revert that change and see if that modified kernel config now
works again.

Have a look at

, at first glace it may answer your problem.

when i used gcc 4.5.1 the problem disappears. it seems that every kernel
should be compiled with appropriate gcc version.
