Heh, if you can find a hub with more than 7 ports, please tell me where so I can buy one. AFAIK, the USB hub code has never been tested with a hub with more than 7 ports. Anyway, there are plenty of very reliable hubs with less than 8 ports. > If it is a common problem then more and more people are going to face it and > my question is. > > Can there be anything done in the code that would enable this to not be such > a problem?

The log looks like the hub or cables are flaky. Have you tried without the hub? Have you tried with a different hub?
