Mmm, didn't you receive my mail dated

“
there is a /sys/bus/usb/devices/2-1.1.1/2-1.1.1:1.0/ttyUSB0
directory. Conversely, /sys/dev/char/188:0 is a symlink to
../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1/2-1.1.1/2-1.1.1:1.0/ttyUSB0/tty/ttyUSB0/
”

“
That however will still let brltty emit some characters to the device,
which can probably upset it.
”

and the latter is probably already a very bad thing for whatever device
is connected to the serial converter.
