To verify that your driver is working, you should see a difference in the following pictures after plugging the CH340 to a USB port. To check that the CH340 enumerates to a COM port, you can open the device manager. You can click the Start or ⊞ (Windows) button and type 'device manager to quickly search for the application. If your port is a combo eSATA/USB port, it might only be offering enough power to drive USB devices, not necessarily SATA drives. If you have a way to test with an enclosure or adapter that uses a regular SATA cable and then a wall AC adapter, I'd be curious if that worked. Windows may install drivers for select devices, say the graphics card, under certain circumstances. This happens by default for instance when the device is setup, but may also happen when Microsoft pushes driver updates through Windows Updates.
