Should be printed on the chip. You can also go into the device manager on your computer and go to either the serial port or it might show up as an unrecognized device.
If you bring up the properties there will be an option to update the driver.
From memory I think the FT232 is supported by practically everything, the CH340 required drivers on earlier machines but worked fine straight away in Win10. The CP2102 was initially unrecognized on my Win10 but after choosing to update the driver it worked fine.
Right now the arduino is connected and in proprietors I can see that:
But! if I disconnect it now, it wont connect again(unless I try a lot and than randomly it will), when it doesnt connect good, the device goes under the: Universal serial bus controller, and it says that it cant recognize it, when It I try to update, it says its already updated.
