Any Idea why my Computer is hanging when I insert certain USB?

you can check if there is a virus in your computer or usb

First of all, have you tried inserting other flash disk drives or other usb devices, to determine if the same problem occurs. Also, what's your operating system? Anyway, since you mentioned that your computer is having a problem finding the appropriate drivers for the usb drive, I guess that is the potential cause of the problem. Also, you could try this, restart your computer, then while it starts to boots, quickly press F8 to load and choose "safe mode", this will load the computer with default settings, drivers, etc. Check if your flash disk will work on the computer.
