Hi, dear niubility friends !
Here I just run the Virtual COM example which is in MQX4.0 USB device cdc folder.
Above all, everything is fine when I have connected the Virtual COM port to a PC which was installed XP operation system.
Then I changed it to the Win7-64 PC and I found that the inf file, recognized as the driver for XP, was not worked.
Can anybody tell me where to get the driver for Win7-64 OS?
Best wishes for all viewers!
