I have a Lenovo 3000 Y410 Windows 7 64bit. I am having a problem with my laptop because it does not install usb devices, it detects the devices but cannot install it. It appears on the device manager but with exclamation mark. I've tried to update the drive but always sayes "driver not found". Even the troubleshooting didn't do any help. These are plug and play devices (flash disk, external hd, usb hub, usb keyboard, wireless mouse) that should automatically be recognized by Win7. These device works perfectly fine with other machines. Each time there is a driver issue everyone can only suggest is that go to the manufacturer's website and download the drivers. However, these are plug and play devices, if that is the solution then I would be downloading each driver for every flash disk that I connect to my machine. I think that's not right, I doubt that the problem relies on the device rather there is something wrong with the OS or the machine.
Any thoughts about this?
