Hi Dave,

thanks for the swift answer. I tried usb:/dev/ttyUSB0 and usb:ttyUSB0 and same result. Log is attached. I cannot get rid of the adapter, since RS-232 is the default adapter, thus I need the USB adapter to make it run on modern PC. It didn't work through the original RS-232 connection on an older computer, too. Could it be broken? It's a shame, since the display is working correctly with it's system messages.

All the best,

Jakub

Your log shows that the device isn't responding. Try using a direct USB 
connection, i.e. get rid of the serial adapter, and specifying usb: (yes, with 
the trailing colon) as the device. So:

    braille-driver bm
    braille-device usb:
