The problem is that I have plugged in the USB drive (A sandisk mini cruzer) and it is not working. All the USB drivers are installed, everything is ok in BIOS and I have made sure all the services that need to be working, work. I also checked device manager and it was not there. It LOOKS like it should be working, but the light thats supposed to be on the USB drive isnt lighting up and there is no removable storage found in my computers.
