Issues Passing Through TWAIN Document Scanner to Windows VM in Parallels

Hi everyone,

I'm looking for some help getting a document scanner working in Parallels Desktop on a Mac with an M4 chip.

My setup:

• Mac (Apple Silicon - M4)
• Parallels Desktop running a Windows VM (ARM version of Windows)
• Canon DR-C225 document scanner (TWAIN compliant)

My goal is to use the scanner inside the Windows VM with applications that require TWAIN support.

What I've tried so far:

• Installed Canon drivers inside the Windows VM
• Connected the scanner via USB through Parallels
• Tried connecting the scanner and sharing it via Mac
• Confirmed the scanner works correctly on macOS

The issue:

The scanner is not detected at all by Windows
Or it connects and fails to load the scanner driver.

From what I understand, this could be related to driver compatibility (x86 vs ARM), USB passthrough limitations in Parallels, or TWAIN not behaving well in a virtualized environment.

What I'm trying to figure out:

Has anyone successfully used a TWAIN scanner (specifically Canon DR-C225 or similar) in Parallels on Apple Silicon?
Are there specific Parallels settings for USB/device sharing that make this more reliable?
Is TWAIN even fully supported in this setup, or is there a known limitation?
What workaround would you recomend?

I'm trying to determine whether this is something I can fix with the right configuration or if it's a limitation of running Windows ARM in Parallels.

Any insight or working setups would be appreciated. Thanks in advance.
