USB hub not detected

Hi all..
I am using BB-C4 with angstrom distribution. when i connect USB hub to
the board. its not been detected.. what may be the problem.. I am
using USB DX-164... should I use externel power supplied USB hub...
pls help me in this regard...

Just see if your kernel gives any message after you connect the USB-hub to the Board…

use dmesg | tail

If there is any message, then it means, you hub needs more power. Using an external powered hub, will make it work…

Else, you consider checking the driver of USB.

Regards
