Driver Recognition and Device Exception Issues
Q1: Driver Recognition and Device Exception Issues¶
Problem Description¶
When using firmware with different configurations or channel counts during development or debugging, device recognition exceptions may occur, or the device may fail to function properly after recognition exceptions.
Root Cause Analysis¶
When the recording channel count is modified, the new configuration does not match the configuration cached by the Windows system, causing the system to fail to correctly recognize the current device state. In such cases, it is necessary to clear the cached data and re-recognize the device.
