+Non-default drivers for commodity chips
+---------------------------------------
+
+Some vendors include common USB chips in their products yet assign device
+specific VID:PID pairs. Which results in the necessity for extra steps
+before the serial port can be used:
+
+- GW Instek VCP, found in GDM-8000 and probably other meters: Install the
+ vendors Windows driver to get access to a COM port. Or force the driver
+ assignment on Linux:
+ # modprobe cp210x
+ # echo 2184 0030 > /sys/bus/usb-serial/drivers/cp210x/new_id
