The machine now has a Silicon Integrated Systems usb hub lspci -vvv etc. might help. Have you read the FAQ? I've seen a few comments about problems with SiS. I have a feeling that some of them were sorted by the most recent kernel, see for example http://www.mail-archive.com/[EMAIL PROTECTED]/msg18693.html but I haven't gone back through the archives to check all the details. Have you Googled for something like "SIS USB kernel 2.6.1" ? There are lots of SiS kernel fixes mentioned. > can't get it working at 2.0 I'd forget USB2.0 with that kernel. Try 2.6.1. > 4.

Try 2.4.24 if you can't try 2.6.1, some of the fixes get back-ported. > Everything seems fine apart from the large numbers of the messages, > but about 5-6 times a day, there is a kernel panic and crash.

There have been a *lot* of changes in the USB code in recent weeks, try the latest kernels and let us know what you find. Whatever you find with the new kernels, read the FAQ and post all the information it asks for.
