Unknown Device in Device Manager is one of the problems that a PC user might encounter regarding hardware devices; it is usually indicated by a warning symbol or a sign such as an exclamation or question mark.
This article will tackle the most common causes of why Unknown Device Errors in Device Manager occur and possible solutions, both manual and instant – which will save you lots of time and energy.
Most Common Causes:
- Missing device driver(s): Most hardware devices function correctly without additional device drivers because of the built-in drivers incorporated in the Operating System of a computer. Still, in some cases, an additional device driver will be required if the hardware device does not suit the required and supplied Windows class drivers. Absence of the required driver results in a device being accounted as Unknown Device in Device Manager.
- Unrecognized Device ID: Each hardware device has a particular identifier used by your computer to verify hardware devices; this identifier includes IDs such as Vendor ID, Device ID, Subsystem ID, and other IDs. If your computer does not recognize several or any of these IDs, Device Manager accounts your device as unknown.
- Faulty or Defective Hardware: A hardware device might sometimes work improperly, failing to be recognized by your computer. This scenario might also be true with defective devices which might work for a couple of times but will not work for your next utilization, thus being displayed as an Unknown Device in Device Manager.
a) Manual Solution: Manually fixing Unknown Device Errors in Device Manager may require patience and willingness to risk the vulnerability of your computer. Here are two possible ways for manually fixing this problem:

- Searching Online: To be able to search online for a device driver, you must gather important details regarding the problematic device. Follow these steps: Right-Click on the problematic device > click Properties > Details tab.
