I've got three 4-port hubs on my system. From time to time after a reboot, some of them don't enumerate properly, and you have to unplug and replug them. Is there some way in software to get Windows to rescan them? Of course that won't do any good if the USB hub that your mouse and keyboard are on is the one that doesn't get enumerated properly, but I'm tired of reaching into the back to unplug them. Also is there a known limit on how many USB devices that can be put into a single machine? I have at least over a dozen USB devices connected at a time usually, sometimes more. Yousuf Khan

I've been having a problem with my wireless keyboard and mouse for a long time. They don't work at boot until the OS starts and they will not wake the computer from sleep (Windows 7). Another response in this thread said that they should be connected directly to a port on the motherboard. Mine was connected to a slot on an expansion card. I moved the plug to the motherboard and it fixed the problem. It appears as if the computer sees hub connections and expansion card connection differently than motherboard connections. Problem solved for me - thanks to the person who posted that solution. By the way, I talked to Intel online chat and they said the problem was that my motherboard is not fully compatible with Windows 7, even though there is no problem when the OS is running.

From: Grandfather of TOS on 6 Aug 2010 14:36 Because I have intuition. If they are so good take them back and ask for a refund and buy something else.
