**The difficult way.**

1. Open Windows devive manager, right click on the device (it probably has a yellow triangle), select properties from the context menu and note down the VID and the PID.

For my clone Nano in above  
VID = 1A86, PID = 7523.

1. Next look up those numbers on the web; e.g. [USB\VID\_1A86&PID\_7523 - CH340 serial converter | Device Hunt](https://devicehunt.com/view/type/usb/vendor/1A86/device/7523) which will tell you that it is a CH340.

2. Now you know the manufacturer (QinHeng Electronics) and you can visit their website and search for the driver: [CH341SER.ZIP - NanjingQinhengMicroelectronics](http://www.wch-ic.com/downloads/CH341SER_ZIP.html)

3. Download it and install it.

**The easy way** that will probably work as most clones use the CH340 chip: do step (4) above, download it from [CH341SER.ZIP - NanjingQinhengMicroelectronics](http://www.wch-ic.com/downloads/CH341SER_ZIP.html) and install it
