Comment 21 for bug 511844

<bryceh> ScislaC, maybe also syslog... like boot with it plugged in, capture that syslog to the bug report, then unplug it, note whatever new stuff shows in the log, then plug it in again, and get that as well
 ScislaC, this may be a general usb hotplug issue unrelated to X, it's probably a kernel issue, but the syslog output would (hopefully) be informative of what is going on
 another thing which might be of interest is to look at the output of lsusb for the three configurations as well
 in theory the first and third cases should have identical lsusb output
