    I am using Catalina ver 10.15.5 and Parallels ver 15.1.4
    If i look at the USB controller icon i can see the device I am trying to connect to but when i run the application that uses this device it reports
    'cant find USB device.'
    This was working some time ago, but this problem might have started at around a OSX ver lower and parallels < ver 14 (about)
    The USB printer works correctly
    How do I resolve this ?
    thanks

    Hi, we've received your reply:
    Hi
    It did re-install from the MAC ok, but it didnt help
    this a XP virtual machine running a windows batch file
    This exact pk2cmd.exe file runs on a real XP machine
    this are the USB devices it sees, and you can see it recognised the
    Pickit2 programmer
    what can i try next ?
    Please advise
    thanks

    Do you have any other virtual machine to test the same behavior?
