When I plug in any storage device into my computer in my thinkpad T510, for example, a camera, or a USB stick, it doesnt work, and the drive does not show up. In device manager, I see a ! triangle next to something labeled USB mass storage device. In device status, it says
Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)
How can I fix this? A temporary fix is to reboot my computer, but that only lasts until a device is unplugged, or sometimes it doesn't work at all. My Mouse, Keyboard, and Bluetooth adapter work fine.
