Hi, Sarah! > There are two patches that Greg pushed to Linus yesterday that should > solve this issue: > > e2b0217 xhci: Add defines for hardcoded slot states > 001fd38 xhci: Do not issue device reset when device is not setup > > If you test with latest tree, it should fix your issue.

I applied the two patches (with minimal adjustments) to a 2.6.39 kernel and they worked well! I append the kernel log created by attaching a USB-3-pen-drive. It contains several warnings. I'm also not sure, whether the pen-drive works at its full speed (I benchmarked about 37MB/s (read), but expected about 70 to 90MB/s). Lots of thanks to you, Greg and all the others involved for this great support!
