Symptom:
When you try to attach a pendrive or USB external hard drive, you get an error message: "Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)"
Windows doesn't recognize the pendrive or external HDD.
Solution:
Uninstall all USB devices from Device Manager, then reboot Windows and reinstall all USB device drivers (download the chipset driver from manufacturer support page and install it).

USB port error - Windows 7 / 8
Sometimes one or more USB port seems to be wrong in Windows 7.
First take a try with a LiveCD, so you can determine whether the operating system is good or not.
If it good, worth to make a full power off. Unplug the PC from the power outlet for 20-30 seconds, then plug in.
If the error still remains, probably the mainboard injured.
