0×0000007e 0xc000001d

stop 0×0000007e error (0xC000001D, 0×8056FAA8, 0xF84D1B44, 0xF8AD1840)?

That's what I get every time a USB device is inserted. Sometimes the last two addresses are changed in place (0xF8AC9B44, 0xF8AC9840) Nope. In a laptop, no other device plugged in USB devices produce this error by inserting (iPod, flash drive, external hard drive)

EDIT: I think the USB circuit your laptop is fried or there is a software problem. If it's a software problem, perhaps one of the file system is damaged. You can try to use the system restore program (if you have the points valid restore to return to). To see if your USB ports are made to measure: If you or a friend has an OEM version of Windows CD, then simply to run the CD. The burden of installing Windows a lot of drivers (including USB drivers), so if a USB mouse or USB keyboard works with the configuration, then you know that the USB circuit on your laptop very well. You can also try running a Linux Live CD on your computer, if you do not have access to a window OEM CD. If the problem is with Windows, then you might have to reinstall Windows with the recovery CD (not a good choice). All the data you want to keep must be saved to DVD before using the recovery CD. Hmm … ——————– Well, if you have other USB devices connected to the computer, remove them first. Some devices USB do not work well with others that are already connected to the computer. In addition, many desktops, the front USB ports are shared (ie linked) 2 USB ports on the back of the computer. So if you have something connected to the ports does not share, there could be conflicts. Another thing to try: If you use a computer desktop and uses the USB ports on the front of the computer, and then test them in the back. (Maybe there is something wrong with your ports before).
