[quoted lines by Alan Stern on 2009/03/18 at 14:11 -0400] >There are two things you can do: enable CONFIG_USB_DEBUG and collect a >usbmon trace (see Documentation/usb/usbmon.txt). Thanks. usbmon works great. The "set interface" is resulting in a -2 error. I've notified the vendor to check what "set interface" might do to their device. One more question: I had another (full speed) device which wasn't expecting the "get descriptor" for the device qualifier descriptor. The vendor has since fixed that problem, even though they're quite convinced that the spec insists that this request shouldn't be sent to a full speed device. In case I ever encouter this again, is ther a way to tell Linux to not ask for that descriptor? -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
