Jieli chips, including the AC4100, are often integrated into "all-in-one" microcontrollers that handle Bluetooth, audio processing, and USB functions simultaneously. Identifying these drivers can be challenging because the physical chips often bear misleading codes that don't match standard public databases. However, system-level identification typically reveals hardware IDs such as USB\VID_E5B7&PID_0811
