Bought a budget USB fingerprint reader like the Chipsailing CS9711 (USB ID 2541:0236) and Linux Mint can’t see it? You aren’t alone. These “Match-on-Host” devices don’t ship with libfprint support by default. A community driver gets them working in a few steps.
Identifying the Hardware
First, verify your device ID by running lsusb in the terminal. Look for:
Bus XXX Device XXX: ID 2541:0236 Chipsailing CS9711Fingprint
If the device shows up but fails to “enumerate” (no name appears), plug it straight into a motherboard USB port. A USB hub often can’t supply steady power.
