• Windows 7
my prolific pl2303 usb to comport dirver problem
  • Solved for me: Win7 with Sitecom CN-104 V2 (older PL-2303 based cable)



    Seems like there are a lot of people experiencing problems with PL-2303 based USB to Serial cables in Win7 or Vista. Searched all over the internet and found tons of driver (ser2pl(64).sys) versions ranging from 3.2.0.0 to 3.3.11.152, but despite all the efforts
    none worked for me and looking at all the posts here, there still are quite some people who can't get it to work.




    But luckily I found a solution that works for me and I hope it helps others too !



    On the website of ICIDU.com (who amongst others sell USB to serial cables), I found 32 bit Vista and Win7 drivers. The version of the ser2pl(64).sys is
    3.0.1.0, which seems to me the first/oldest version I have found so far. And guess what: IT WORKS !



    I first uninstalled ánd deleted the old drivers and then updated the drivers (Update driver > Browse my computer for driver software > Browse) with the ones I found

    here
    . After a few seconds I got a "This device is working properly" and it works like a charm !



    Hope this solves some of your problems too !!
