USB high-speed (ehci-hcd) driver fails on a motherboard with SB600 chipset. According to Linux kernel developer (http://bugzilla.kernel.org/show_bug.cgi?id=11599) this is due to a hardware bug in the chipset. Apparently there is no solution.
Ha anybody experience with this chipset on Linux? Any suggestion?

Very briefly- my wife has a laptop with the RS690/SB600 and I booted a live CD on it once and used a USB thumb drive. It worked, but it was a while ago. I can't say much else on the topic.

Thanks, it looks like I found the problem, see the http://bugzilla.kernel.org/show_bug.cgi?id=11599 for details. Basically, a misbehaving USB hub connected to one of the motherboard ports was causing the whole USB peripheral on the SB600 to downgrade to low speed.
