OK.
I have not received any reply to the following question. Thats fine of course.
I have since tried to access a Kodak 240 digital camera with gphoto.
I also get lots of "bulk_msg: timeout" messages.
I have a simple question:
Is this likely to be a problem with the uhci controller?
and another, secondary question:
Are problems like this common?
