USB Serial Driver for Win11 on M1 Mac

I just installed Windows 11 under the latest Parallels on an M1 Mac. To my (very pleasant!) surprise, some software that says it absolutely won't work in that configuration actually works just fine (albeit a bit slowly), but I'm having issues with the USB interface.

I have a USB device that shows up as "Port->COM4:" when I connect it to a PC or Parallels Windows on an Intel Mac, but on this machine, it shows up as "Other->Alchitry Au" (the device name) and my program won't communicate with it.

I believe this is just a simple serial interface, but I'm not an expert.

Any advice for how I can fix this? I have a workaround to use the Mac for that step, but it's kind of a nuisance.
 
Dear Eric,
did you found a solution for your problem?
I have exactly the same problem with a FEIG USB device
I have uploaded a print screen
under Windows 10 it was working absolutely perfect, and now I cannot find the solution
if someone can help this would be highly appreciated

I have not found a solution. Weirdly, I was able to install Arduino IDE, which uses the same chipset and it works just fine, but it still doesn't recognize the Alchitry board.
 
Hi gentlemen, you must have an ARM version for Windows of the driver. At the moment, you seems to have a X86 driver that will indeed not work on an ARM OS.
 
Sorry to reply to an old thread, but wanted to reply incase others fine this thread who have this issue as I found a solution.

Instead of passing the USB device from macOS through to the virtualised Windows 11 ARM, I passed the COM port instead.
To do this I did...
  1. Make sure you have Parallels's Configuration window open for the Windows 11 virtual machine.
    • ie go to Actions menu > Configure
    • This is important as after you shut down the virtual machine this menu can be harder to find
  2. Shut down the virtual machine, as this setting can't be configured while it is running
  3. In the Configuration window
    1. go to the Hardware section
    2. if the padlock at the bottom is locked, unlock it
    3. click on the plus "+" symbol just above the padlock
    4. select Serial Port
    5. select the correct source, for me it is "/dev/cu.usbserial-10"
    6. click on the padlock at the bottom to save the settings
    7. close the Configuration window
  4. Start the virtual machine back up, and now you'll find the COM port listed in Device Manager :D
More details, including pictures, can be found in the Parallels Knowledge Base article "Adding USB devices through COM port to virtual machine" at https://kb.parallels.com/en/6318
I hope this helps someone.
