alisonnic replied to Jack_Bauer's topic in HardwareThanks so much for this suggestion! I have a Gateway laptop that's worked fine for a year and a half. Suddenly, after a scenario in which I was plugging and unplugging a USB device after waking the laptop up from sleeping, I began getting USB Device Not Recognized messages for all of my USB devices except my mouse. After turning off the computer, unplugging it, and removing the battery and leaving it to sit overnight, when I booted up in the morning, the USB ports were back! I can use my printer, flash drive, Treo synch, and iPod. However, now I have a new problem. :x Now the iPod and the flash drive give me a warning message when plugged into three of the Gateway laptop's four USB ports: "This device can perform faster "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port. For a list of available ports, click here." If I click on it, it shows a six-port USB 2.0 controller, even though the laptop only has four USB ports. In Device Manager, it shows one USB 2.0 Enhanced Host Controller and three Universal Host Controllers (presumably USB 1.1). Gateway support says it's supposed to show this, and that the USB 2.0 controller's characteristics are supposed to cascade down to the other controllers. Their only fix is a complete format/reinstall of Windows. I've twice tried uninstalling all the USB controllers and root hubs from device manager and letting the computer find them again and reinstall them, but with no change in this behavior. Anyone know how to get the laptop to see all of the controllers as USB 2.0, as it used to? BTW, I'm on Windows XP Home SP2. Any help would be greatly appreciated!
