This product has no instructions. The included CD has more then 1800 files. It took a lot of searching to find the correct driver and get it working. The CH35X worked for me on Windows 10. I can now connect to the serial port on my radio. With a little instructions in the product copy this would be a solid 5 star product.Update: I just moved this from one computer to another. The CD is long gone. I searched for wch382l driver and realized that the chip driving this board has 2 serial and one parallel port even though the parallel port is not broken out. Installing this driver worked.

I needed the 2 com ports. The Install went well, however, the info on the correct driver to install for this unit is rather vague. This led to installing the incorrect driver which only allows 1 of the 2 ports to work. Tried multiple times to clear the driver and load the correct one each time only the 1 port worked. So I only have 1 port that works and I have to switch cables manually on an embedded PC every time I want to send data to a particular machine, which defeats the purpose of a 2 port card.....

Wasted more time trying to find the right drivers on the included disk. Long list labeled with driver numbers and not descriptions of the adapter. Finally found one for an adapter with an additional port and got tired of looking, made it work. Spend more and buy better quality.

It is what it says it is! Adds 2 extra serial ports via PCI-e. Comes with 2 small form factor brackets for SFF PCs which is very nice.The driver on the CD that came with it didn't work. I had to do some googling to find the correct driver. If you do a google search for CH38 windows 11 driver, you'll be able to find it. It should be on the wch-ic(dot-com) website.
