Well, shows what I get for trusting hardware. Your device is broken, its configuration descriptor claims its configuration is 1 while it returns 98 (a non-existent configuration) to a get-configuration request.
You should try to get the hardware vendor to fix their device. Meanwhile, the CVS code is updated to check for this specific broken hardware bug, and if the lying device has only one configuration, it will assume that's the active config. So it should work for your device. On Wed, 13 Apr 2005, Dmitri Kostioukov wrote: >Here's a new trace.
