Most devices we use today are USB devices. USB is an acronym for Universal Serial Bus, a type of computer port where a piece of equipment (device) connects to the computer. The most popular USB devices are cameras, external drives, iPods, microphones, printers, smartphones, scanners, joysticks, tablets, webcams, keyboards and mice.
The most common causes are:
- The currently loaded USB driver has become unstable or corrupt
- The USB controller itself may have become unstable or corrupt
- Your external device may be entering selective suspend or sleep mode
- The PC motherboard may need updated drivers
- Device detection fails and Windows gives popup message
- Detection/disconnect chimes
- Device randomly starts working
- Check the age of your device driver and update it if there is a newer version available from Windows Update, device manufacturer websites, or 3rd-party updater software.
- Uninstall, reboot, reinstall driver
- Have you recently updated Windows or applications? Check for known compatibility or stability issues.
