Avoid the mini-CDs included in older boxes. Download the latest version of the "USB Temperature Humidity Datalogger"

software directly from the CEM (Shenzhen Everbest Machinery) official website or a verified distributor’s support page. This ensures you have the drivers built for Windows 10 and 11. 2. Solve the "Device Not Found" Driver Issue

). This forces Windows to recognize the specific USB-to-Serial bridge used by the DT-172. 3. Address Administrative Blocks

in the Device Manager and manually reassign it to a lower number (like COM2 or COM3).
