[BRLTTY] [Fwd: No braille support when using Alva Satellite via USB (protocol)]

[Thijs Koerselman]

Hi all,

I'm currently stuck on the exact same thing. I'm not using NVDA, but I'm
trying to use brltty directly from an application I'm developing. I have the
same braille display and I couldn't get it to work either. I have first
tried USB and later on COM using a USB->COM adapter. Below is my output from
an attempt to run brltty in debug mode from the command line. Today I've
tried a different (older) ALVA device which only has a COM connection but
also without any luck.

I'm using the (unofficial) Windows release of 3.10
