The original Blueprint BPTD110BT driver (v1.0) had a known memory leak affecting Windows 10 20H2 and above. Symptoms included increasing latency and eventual disconnection after 45 minutes. The (v2.3 and newer) patches this leak, adds proper Handsfree Profile (HFP) support, and resolves the “connected but no audio” bug.

1. Download the USBDeview utility (from NirSoft).
2. Run as administrator and remove ALL entries related to “USB Serial” or “CH340”.
3. Uninstall the printer from Printers & Scanners in Windows Settings.
4. Perform a clean boot (disable all non-Microsoft services via msconfig).
5. Reinstall the driver using the steps above.
