Occasionally when my system wakes up from sleep, this message is displayed:
"Your usb composite device can perform faster if it was plugged into a hi-speed port".
It shows what appears to be all the usb ports in the PC with the available hi-speed ports highlighted. What is a "composite device"? I do have a port expander plugged into one usb port on the PC which in turn has 4 usb device ports being used.
I've never seen this message while using Vista, only since "upgrading" to W7. Now I do supect the PMD (Personal Media Drive) although the "port expander" could be suspect? Once again, what is a "composite device"? Thank you

Elchucko, your back!
A USB composite device is one that has more than one iterface, such as, USB, USB 2.0 and Firewire. Since, the PMD plugs into a prioprietary bay, I am not certain that this is your problem. I would disconnect all USB devices from your computer and reboot. Then, plug one component in at a time and reboot. When you get the message, you will know which device is causing the error. This is the simplest way to diagnose the problem.
