Hi all,
I am using BeagleBoard xm Rev C and I can't use the USB ports every
time I connect a usb keyboard or mouse I get an error
hub_port_status failed (err = -71)
cannot reset port 5
cannot enable port 5 May be the USB cable is bad?
I am currently using Ubuntu 11.04 demo image with the latest kernel
and Xfce
Any help please?
Thanks in advance,
Hi Fadi,
Do you see the same issue when using the Angstrom image that came with
the xM-C? I had seen issues with heavy data transfer over usb (http://
groups.google.com/group/beagleboard/browse_thread/thread/
ce2956cad6c3c30e#). I've had those boards replaced but haven't had a
chance to test them.
Kate
Can we see a full boot log, with the keyboard/mouse plugged in? (do
other usb devices work?)
Which "latest kernel"?
Regards,
Thanks all for your reply,
@Kate No i didn't face the same problem with Angstrom
@Robert
Here is the log and I have tried other devices but they didn't work
