Well, I just tried 2.5.49. With it, "insmod hid" gives the same two error
messages ("ctrl urb status -32 received" and "usb_submit_urb(ctrl) failed") and then hangs.
What hangs -- the whole system? Or just some part of USB?
Someone recently noticed that uhci-hcd.c has logic to halt control endpoints after protocol stalls ... which really shouldn't be there. Maybe if you delete usb_endpoint_halt() from uhci_result_control() then your problem will go away.
It might be helpful to send along the "lsusb" output, I seem to recall that it understands a few more things about HID.
Well, according to 'lsusb -t', the device of interest is bus 1 dev 3, but
there is no /proc/bus/usb/001/003 file, so lsusb has nothing to parse.
Huh. That shouldn't happen. Looks like some enumeration path has an error cleaning up after some kind of error. This would be a different bug from the UHCI issue, particularly since the "usbfs" data is only partially initialized... - Dave
Here's the relevant section of /proc/bus/usb/devices, in case that helps: T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 3 Spd=1.5 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=050d ProdID=0980 Rev= 0.06 C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 20mA I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=(none) E: Ad=81(I) Atr=03(Int.)
