USB Serial Adapter for old vinyl cutter

[TimT15]

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

I'm also having issue with the Keyspan USA-19H on an M1 Mac with Windows 11 in Parallels 18.0.3. The device is shown in the Parallels Devices-->USB but the Keyspan serial assistant doesn't find it. The driver can't be updated automatically and the one from Tripp Lite doesn't help.
