Thanks in advance. Would you be able to test an 8.0 kernel with PAE enabled? 8.0 has a completely rewritten USB stack, so there is a chance that the bug in 7 might not be present in 8. You can also try posting on freebsd-usb@ since the folks working on the USB drivers tend to hang out on that list. -- John Baldwin
