There is no cable, the stick is connected directly to the connector. The device works fine with another computer. I would like to point out that I am pushing in a 2.0 stick into a 1.1 controller here and I think an error is acceptable, but what is not good is that the driver/system will be in a state where the USB port is unusable after this and additionally cat-ing /proc/bus/usb/devices will hang after this situation. In other words the driver handling of the error does seem to have a flaw. (A spinlock left activated perhaps?) I also would like to point out that the computer where this happens is a fairly slow 486, could there be a timing problem somewhere?
