Description Lorand Attila Balogh 2011-04-15 15:13:53 UTC

Usb hubs don't work in the kernel version 2.6.38.

The usb hub are detected but give the following error:

[ 3.180085] usb 1-2: device descriptor read/64, error - 71
[ 3.404042] usb 1-2: device descriptor read/64, error -71
[ 3.620050] usb 1-2: new full speed USB device using uhci_hcd and address 5
[ 4.028040] usb 1-2: device not accepting address 5, error -71
[ 4.140042] usb 1-2: new full speed USB device using uhci_hcd and address 6
[ 4.548040] usb 1-2: device not accepting address 6, error -71
[ 4.548116] hub 1-0:1.0: unable to enumerate USB device on port 2

Tested on a 4x port external usb hub. The problem showed up in kernel version 2.6.26. Usb hubs worked correctly before kernel version 2.6.26.

Please post this on the linux-usb@vger.kernel.org mailing list so the
developers there can help you out.

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing 
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
