As you said, duplicate the log under Linux and the device will work. The problem is that you're not duplicating the log. The SnoopyPro log shows that Windows always has two Bulk or Interrupt URBs pending, but your program doesn't use any. > I don't want to become an expert on writing USB drivers, at least not at > this time.

It's not a question of Linux vs. Windows, it's a question of making your driver do what it's supposed to do. As for not wanting to become an expert... That's understandable, but you _do_ have to become something of an expert on writing drivers for the type of device you're interested in. Otherwise you'll never be able to make it work.
