The problems you describe are exactly among the reason why I don’t run virtual 
machines. I don’t want to deal with the extra complexity and unreliability, 
especially in attaching Braille displays.

I know this might not be ideal for practical reasons, but can you run macOS on 
the Mac, and other operating systems on other hardware, so you can avoid 
virtual machines altogether? Realistically, this may be your only good option, 
given the driver and pairing issues you mention. Alternatively, can you find 
macOS substitutes for whatever applications you want to run under Windows, so 
you can avoid Windows entirely, at least on the Mac?

Unless you can complete the Bluetooth pairing non-interactively, the request 
for a PIN that presumably shouldn’t be happening is a real obstacle.

For USB, is there a screen reader you can run which doesn’t require drivers to 
be installed, or do all Windows screen readers require drivers for this 
particular display? If the driver isn’t loaded into the kernel, you may be able 
to run it using x86 emulation. I’m assuming that kernel code can’t be run under 
the emulator. Trying to avoid the driver may be a good path to take. If you 
were running a Linux, you wouldn’t have this problem, as the BRLTTY package 
includes the driver for each display, and it can be compiled for Arm64.

Unfortunately, I suspect that “don’t get into this situation in the first 
place” may be the only realistic answer. You could ask the Braille display 
manufacturer to build Arm64 Windows drivers, I suppose. I don’t know how much 
effort would be required for them to do so.

Subject: I'm interesting Windows virtual machine Braille Display dilemma.
Good morning everyone, I am having an interesting bra display dilemma. I'm 
getting ready to go on a trip. And I am only planning on taking one braille 
display with me.

I know that many on this this use being more fusion, but after doing some 
research it appears they have recently dropped all Bluetooth support. So 
unfortunately unless something is radically different I don't think I can use 
being more fusion with the rail display I'm planning on taking. On the other 
hand, Parallels desktop for mac does have Bluetooth support. But here's the 
interesting twist, the braille display I'm planning on using is seeing in the 
virtual machine. I can only connect to it if I use a pin code. Sadly the 
braille display does not allow for the entry of the pin code on the device 
meaning the braille display.

The device I think it's gonna be very difficult to accommodate. It's the 
braille since six. Can I get to my Mac MacBook Pro M2, running macOS sequoia no 
problem! Works great! But if I need anything from Windows 11 Pro, and if I need 
to read it and set up attempting to hear it, appears to be a big no go. Does 
anyone on the list have any suggestions?

Just so that everyone knows I have talked to the tech-support people in Austin. 
They suggested that I might reach out to the list. I've done a little tiny bit 
of work with parallels but they said this was a couple of years ago.

The company and I thought I could use USB, to do this. But the USB drivers are 
unfortunately meant for Intel hardware. Hence they are useless on an arm 
machine. I hope this email clearly explains my dilemma?

Please note that I'm including my signature below only because I'm working on a 
lot of things and this email is coming from my official email address. But the 
question is coming from me the person, not me the president of the deaf blind 
division of the national Federation of the blind.
