    Hello,

    I've recently installed parallels, hoping I could use my vinyl cutter with my MacBook, as all the Mac software doesn't feature my specific model of vinyl cutter, or straight up doesn't work.
    Running Win11 in parallels works surprisingly easy, but unfortunately I can't get my vinyl cutter to cut anything.

    When I plug my USB/Serial adapter (TrippLite USA19-HS) in, and click the prompt to connect the USB device to windows, the VM freezes and I have to hard-reset the whole MacBook to get it working again.
    So I tried to use the "Serial Port" feature in parallels, I can see the COM Port in device manager, but if I send anything towards the cutter, it doesn't cut anything.

    Is there anything I oversee in regards of USB passthrough to make it work? It is the single reason I'm thinking about buying parallels, so it would be a dealbreaker if the cutter wouldn't work.
    thanks in advance,
    Tim

    Hello TimT15, Please refer to the knowledge base article to troubleshoot the USB on Parallels Desktop. Thanks.

    Hello GampaA, I followed through the article, but I don't even get so far as the VM installs anything as it crashes when I click "connect to VM". My Mac recognizes the device and I can fully use it under MacOS. So there seems to be some kind of problem with the device and parallels or Windows.

    Thanks for the info I tried downgrading to 17.0.0/17.0.1 but unfortunately it still didn't work.. So we have to wait until it gets fixed? Or is there more to the downgrade than reinstalling the correct build? Do I need to do anything in the VM?

    this is getting more and more mysterious here.

    hopefully someone from the parallels team can help you!

    and hopefully parallels will soon find a solution for the annoying usb-problem:

    Yeah, I hope so too!
    For now, if I want to use my vinyl cutter, I have to use an extra windows machine, which kind of defeats the purpose.. The Cutters software works fine in Parallels, but I can't communicate due to the unfixed USB issues!
    I hope they will find a fix soon, or else I have to check out competitor's software :confused:
    Thanks for your help though!

    I'm just guessing here, but is the USB to the vinyl cutter USB 2.0 or 3.x? Wonder if something they changed for ARM did something weird in the way 2 vs. 3 works.

    No guarantee this will do anything (I'm still on Intel), but try this:
    1. Shut down your Windows VM.
    2. From the Parallels menu for the Windows VM, choose "Configure...", "Hardware", "USB & Bluetooth", then click the "Advanced" button.
    3. Toggle the Enable 3.1 checkbox to be the opposite of whatever it is now and click Ok
    4. Close the Configure window and restart the VM to see if the vinyl cutter now works.
    5. If it still doesn't work, restart from step 1 (but only once, just to put it back the way it was - no need to be in a loop, lol).

    Again, it's a shot in the dark, but sometimes things like this shock things into place.

    Sounds like a good idea, but unfortunately the "advanced" option is not available for me. I think it has something to do with the USB3.0 eXtensible Host driver (which isn't available for Win11 for ARM).

    Damn. Was worth a shot.

    As a developer, I get the impression that trying to merge Intel and ARM in the same distribution was massive mistake for something of this complexity. Most other apps can get away with it because they're not necessarily hardware dependent. But in this case, there's way too many moving parts for something like this to make the code even manageable.
