ISTR a similar issue with the same unexpected command completion code that was fixed with commit b513d44751bfb609a3c20463f764c8ce822d63e9 (in the 3.0 kernel). That should fix was released in the 2.6.39.1 stable kernel. > and I cant seem to use it. > > lsusb shows it as > Bus 003 Device 010: ID 0d8c:000c C-Media Electronics, Inc.

Try running the latest stable kernel (3.0) and let me know if you still have this issue. If you do, enable CONFIG_USB_DEBUG and CONFIG_USB_XHCI_HCD_DEBUGGING and send me the dmesg from the point that you plug in the device.
