Simultaneous USB Ports Malfunction GWL 11/28/2008 2:35:01 PM Yesterday, my computer suddenly issued a series of USB port unplugging sounds. Investigation has revealed that none of the USB ports on my machine are functioning. No USB printer, keyboard or mouse (without PS/2). There were five windows displayed with the following message: "One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it." Occasionally when I try to plug in a device, while no plugging sound is issued, the malfunction message will be displayed. I also have one USB port in a multi-card reader on my machine and it has a Ready Boost device plugged in. This device works when plugged in at Boot, but is unrecognized if plugged in after boot. HELP, I have no clue as to what happened here.

Re: Simultaneous USB Ports Malfunction GWL 12/8/2008 4:36:00 AM Thank you for the response. I answered in another thread that after spending the weekend trying to figure this out, I gave up and assumed it was hardware too. I unplugged everything and took it to the shop where nothing was found amiss. After bringing back the computer all USB ports were functioning normally. Since this happened I was contacted by two other users who experienced the same problem. One explained that her IS people could not bring her USB ports back on Friday. They told her that they would bring a replacement on Monday. She unplugged the computer and left it unpowered over the weekend. On Monday morning out of habit, she booted up the ailing machine and all USB ports had returned to full function. I am now leaning in the direction of some kind of problem that was resolved by the prolonged unplugging of the machines. (Or maybe the Cyber Gods were just playing.) :-) "Richard G.
