Once installed the required driver the computer will recognize the device without problems and we can use it with any compatible program. If you do not have any decompressors you can install WinZip or WinRar. I would start with the CH340 and, if it did not work, I would continue with the PL2303. A little further down, in the download area of this page, you will find several USB controllers to test.
