[BRLTTY] Introducing myself, and a question regarding BRLTTY for Windows

[Felix Grützmacher - Handy Tech Elektronik GmbH]

Hello,
the USB-HID adapter is a piece of hardware that makes the older FTDI USB to
serial-based devices, such as Braille Star 80, available as HID devices so
they can be used without the administrative privileges which would usually
be required for installing the FTDI driver.
So, for example, the adapter turns an FTDI-based Braille Star 40 into an
HID-based one.
Is anyone on here using an Active Braille, Basic Braille or Active Star with
the current BRLTTY? If so, what firmware is running on the device?
I'll test again on another machine just to make sure it's not just this
system having a problem. I'll also test with a Basic Braille.
I'm quite sure you are doing everything right, as we never changed anything
substantial about the USB layer in the Active Braille firmware. So there is
no older and newer communication protocol with Active Braille, it's just as
it always was.
Kind regards,
Felix Grützmacher

I'm sure that's true.

2 strictly uses USB control operations for both input and output wehreas 3
does input via endpoint 81 and output via endpoint 01.

We currently use 2, as mentioned earlier, for the HID versions of the Easy
Braille and the Braille Star 40. We also use it for something (I'm not sure
what, exactly it is) that we call a USB-HID adapter.

We use 3 for the Active Braille, the Basic Braille, the Active Star, and the
Connect Braille.

Is it possible that the difference really should be based on firmware
version rather than one device type? In other words, is it possible that
older HID-based firmware does it one way and that newer HID-based firmware
does it the other way?
