"Burn the Linux into a CD or DVD and boot from optical drive to run it"
If you create a Linux CD as has been suggested by kuwese, all you'd have to do is boot off it & run directly from the disc, no installation is required. You can then try a USB device from within Linux. It it works, you'll know you have a Windows/software problem. If it doesn't work, you'll know you have a hardware problem.
