Re: The dmesg files requested

["Jon 'maddog' Hall" <maddog@xxxxxx>]

Alan and Sarah,

I did as Alan requested in his last email:

>Run another test.  This time, insert the USB drive and a few seconds 
>later do:

>        dmesg -c >/dev/null

>Then click on "safely remove drive", and a few seconds later unplug

The output of this using my USB 2.0 flash drive is attached as file
"alan_request_USB2.0.txt".

I then did the same thing, using a USB 3.0 drive that had three file
systems on it.  It shows the same physical results as the flash drive
did, of having the top port go dead until an "lsusb" or cycling through
the bottom port and back up to the top, but I was hoping it would
"tickle" different code.

Please let me know what else you want me to do.
