Driver Recognition and Device Exception Issues
Q1: Driver Recognition and Device Recognition Exception Issues¶
Problem Description¶
During development or debugging, when using firmware with different configurations or different channel numbers, device recognition exceptions may occur, or the device cannot be used normally after recognition exceptions.
Cause Analysis¶
After modifying the recording channel number, the new configuration is inconsistent with the configuration cached by the Windows system, causing the system to fail to correctly recognize the current device status. In this case, cached data needs to be cleared and device recognition needs to be performed again.
Solution¶
- Connect the device to the computer
- Open Device Manager
- Find the "Sound, video and game controllers" category
- Right-click the related audio device
