Once you have downloaded the driver file (usually a .zip or .exe file), follow these steps:
lsusb
Use the Vendor (VID) and Product (PID) IDs if model name yields no driver. driver bluetooth m-tech bt-05
The primary use case for the M-Tech BT-05 is retro-fitting old computers. A Windows 7 desktop from 2010 or a Linux machine lacking built-in Bluetooth can gain wireless audio and peripheral support for under $10. It is also useful for adding Bluetooth to a Raspberry Pi (if the Pi’s built-in radio is inadequate) or to a PC used as a home media server. However, the adapter has significant limitations: it does not support aptX or LDAC codecs for high-quality audio, it may struggle with simultaneous connections (e.g., a mouse, keyboard, and headphones at once), and its antenna design (embedded PCB trace) provides shorter real-world range (10–15 meters) than the theoretical 50 meters. Once you have downloaded the driver file (usually a
Even after installation, things can go wrong. Here are fixes for the most common M-Tech BT-05 errors: On Linux: plug it in → run: lsusb
The BT-05 works out of the box with btusb kernel module:
lsusb | grep -i csr
