>Description:

My D-Link DUB-H7 USB hub doesn't work if it is plugged into one of the
machine's USB port at boot time.  Furthermore, if I then disconnect
and reconnect the hub, it still doesn't work.  The only way I can
regain use of the USB port is to reboot.

If I boot without the hub and then connect it, it works.  I can
disconnect and reconnect it, and it still works.

Here's the dmesg from booting with the hub plugged in.  Note the
message "uhub4: device problem, disabling port 4".
