I'm trying to pass testusb suite test on a UDC driver. It fails when
running test 10:
$ ./testusb -t10 -D /proc/bus/usb/002/016
unknown speed /proc/bus/usb/002/016
/proc/bus/usb/002/016 test 10 --> 75 (error 75)
It actually fails while running case 10 and it seems to test the host...
Here's a part of usbmon's trace while running this test

My host is a fedora 2.6.12-1.1381_FC3, with a uhci HC.
The request was terminated with a "EOVERFLOW" instead of "EREMOTEIO"
status, and I don't understand why...can someone bring some light
here ?
Thanks
