Hello, Since for my job I'm already working within qemu, maybe now is a good time to at last write a virtual braille device. The question that was still pending was which device to implement. I had a look at USB devices which are supported by all of brltty, suseblinux and libbraille, and checked which display sizes were available. It looked to me like the Alva or the Baum protocol were quite suited. What is interesting in the Baum protocol is that it has a generic way to get the size. However as I understand it the USB ID is supposed to match the size, thus reducing the possibilities to not so many (24, 40, 32, 64, 80), and of them suseblinux seems to only support 40 and 80. The good thing with the Alva protocol is that there is a lot of possible sizes, and most of them are supported by both libbraille and suseblinux. In both case, it looked like the serial and USB protocols are the same, thus factorizing the code between a USB and a serial variant.
Any opinion on which one I should rather implement, maybe based on other considerations like the buttons, the JAWS/WindowEyes support, etc?
