Setting Up the Chipsailing CS9711 Fingerprint Reader on Linux Mint
If you’ve purchased a budget USB fingerprint reader (like the Chipsailing CS9711, USB ID 2541:0236) and found it undetected on Linux Mint, you aren’t alone. These “Match-on-Host” devices aren’t supported by default in libfprint, but they can be brought to life with a community driver.
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 is detected but fails to “enumerate” (doesn’t show a name), ensure it is plugged directly into a motherboard USB port rather than a hub to provide consistent power.
