lsusb to list out your usb devices, a strange looking entry should appear, also the tail of your dmesg or var log system messages should say it was able to initialize. If it was unable to initialize, power down your computer system, and start it up again. It’s typically a USB port protection to disable certain devices if they are known to cause issues during your computing session (stored on the USB chipset).
A powerdown/powerup (not a reboot) would reinit the chipset completely.
