Description Sergey Smirnov 2007-11-22 01:14:26 UTC
Most recent kernel where this bug did not occur: 2.6.22
Distribution: Debian Armel
Hardware Environment: XScale PXA255 Zaurus C750
Software Environment: Debian Armel
Problem Description:

Normal messages on PDA side

On PC(usbnet) side (kernel 2.6.23):
[170563.539380] usb 3-2: new full speed USB device using uhci_hcd and address 23
[170563.659518] usb 3-2: device descriptor read/64, error -71
[170563.891412] usb 3-2: device descriptor read/64, error -71

The same configuration works with 2.6.22

With 2.6.23 kernel USB Gadget sometimes hangs:
NETDEV WATCHDOG: usb0: transmit timed out

What evidence is there that the problem is the gadget
instead of the host?  That looks most like a host side
issue...

The same PC  works correct with the same PDA  kernel 2.6.22.
If I flash 2.6.24-rc3 on PDA got error on host side.
2.6.23 on PDA hangs usbnet some times.
