Well, I must say that this degree of cooperation from an Open Source project is rather new to me. Did I violate your policy by posting to devel directly? Than sorry, just tell me. All I am asking for are some hints what may go wrong in my case, what the messages e.g. mean. If you are not /able/ to debug this problem in theory (likely I will have to do this on my hardware in real anyway), then please explain why you can exclude a bug in the USB stack. Otherwise, with my currently limited detail knowledge of the involved components, I may easily end up being bumped between both projects. Jan
