Here's what I've done so far:
-Uninstalled USB, rebooted, reinstalled USB
-Shutdown laptop, disconnect power supply for 15 minutes, reboot
-Ran McAfee and Malwarebytes scan (no viruses detected)
-Reinstalled BIOS and chipset drivers from laptop manufacturer
-Under Power Management under USB, I unchecked the box next to "Allow the computer to turn off this device to save power"
Oddly enough the pedal started working for about an hour or so, but then stopped again without warning. Unfortunately this is the only computer I own. I work from home as well. If there are any other suggestions I'd appreciate it!
