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?
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.
