[BRLTTY] can't load Handytech driver

[marquats at studi.informatik.uni-stuttgart.de]

Hi,

I have now lended a Handytech Braille Star 40 terminal and try to use it
with Windows XP. I have installed the precompiled brltty-win-4.2-2.exe.

The braille terminal is attached to an USB 2.0 port. Windows has
recognized it and installed something with "usb to serial" (can't remember
exactly).

Then I tried to start brltty and my test program using BRLAPI with the
command:
brltty -e -l debug -n -b ht -d serial: > debug.log.txt 2>&1
I have also tried with  -d USB:

It doesn't work. In the log file there are always some messages like:
brltty.exe: braille driver initialization failed: ht -> serial:
brltty.exe: braille driver not found

The application can connect successfully with brlapi_openConnection(),
but the driver Name is given as "NoBraille" by brlapi_getDriverName().

I don't know what to try next. Can you give me some advice?

Greets, Thomas Marquardt
