I use a usb hub to connect to a beagleboard, and plug in a thumb drive
on the hub. It works fine.
But when i remove the thumb drive and plug in again after 2 minutes,
the thumb drive can not work,
I use dmesg to print out the message. I found a message "suspend root
hub", seems that the root hub doesn't wake up when i plug in the thumb
drive at the second times.
Is there anyone who has encountered the same problem before? And can
you please share with me how you solved this problem. thanks.

Did you try the hub on a different system for comparison? Maybe with the
same Linux kernel and then try to upgrade to find out if the problem has
been solved.
