Mounting USB in Gingerbread

SANGILI KUMAR

Hello

I'm using Beaglebone Android GingerBread 2_3_4. I need to use my beaglebone as HOST and want to connect a USB device ( Vendor specific Class).

I have copy the drivers into system/lib,  then i mount the usb using following commands in init.rc below the on boot 

mount usbfs none /proc/bus/usb -o devmode=0666

After re-boot,  beaglebone showing my device as unsupported device

I don't know where the mistake is happened. But I'm sure about the drivers are good. i guess its not getting mount.

Any one can help me to get out of this.

Thanks in advance

    We generally prefer to use built-in class drivers for USB. Is it possible for you to try this way?

    Also could you attach the full kernel log and logcat output if available.

    Dear Vishveshwar

     Thank you for your reply

       Sorry i can't use Built-in Class drivers of USB. I need to communicate with sensor its connected via USB with android device. Sensor communicate with device with its own driver ( vendor specific class USB), I have driver for sensor libusb.so and libusb-1.0.so, already i have copied this into system/lib folder.

    and mounted it with mount usbfs none /proc/bus/usb -o devmode=0666.  

    Below i have attached log details while its booting

    We have not tested user-mode USB drivers with our TI Android DevKits.

    Suggest you to ask at our rowboat community forum http://groups.google.com/group/rowboat  or beagleboard forum http://groups.google.com/group/beagleboard
