[beagleboard] Unable to enumerate USB device in BB rev C4

Hi all,

I have a BB rev C4. I boot it up using an SD card (using
linaro-media-creat), but when I plug a hub 2.0 (with external power supply)
in order to use usb-mouse and key board it respone like this:

[ 78.643646] hub 1-0:1.0: unable to enumerate USB device on po2
[ 79.205963] usb 2-2: device descriptor read/64, error -62
[ 79.510650] usb 2-2: device descriptor read/64, error -62
[ 80.010650] usb 2-2: device descriptor read/64, error -62
[ 80.315490] usb 2-2: device descriptor read/64, error -62
[ 81.041961] usb 2-2: device not accepting address 4, error -62
[ 81.659240] usb 2-2: device not accepting address 5, error -62
[ 81.665405] hub 2-0:1.0: unable to enumerate USB device on port 2

I try with another hub but it behave the same thing. I plug directly my
usb-mouse to BB but it doesn't work.
I searched in mail group but no one have the same problem, can you tell me
what the problem could be? Have no mouse and key board I can't do anything
else :frowning:
If you need more infomation to detemine what problem is, please tell me
because I'm a newbie with BB (and just wroked with Linux two months).
I'm a student and absolutely newbie with BB.
Sorry for my bad English skill. Thank you in advance.

Try a different mouse and keyboard, preferably a non-generic model
such as from Dell.

Thanks,

The problem is my USB hub. It is 1.0 USB hub instead of 2.0 standar
