X Error of failed request: BadValue (integer parameter out of range for operation) - Major opcode of failed request: 101 (X_GetKeyboardMapping)

[Rado9]

Hi,

I successfully installed softwedge. (I needed to install also libraries libx11-dev and libxtst-dev.)
I use Linux linaro-alip 4.9.56 (Debian 9.13).

I set baudrate via sudo stty -F /dev/ttyUSB0 57600 and I run softwedge via sudo softwedge -c /dev/ttyUSB0 -f
Then I opened text editor and I scanned card via usb card RFID reader. In text file I got empty line and letter "y".

Expected result is: 0a 79 00 00 05 00 e6 b4 cc 01 e9 (hexadecimal)

In console I got error:

sudo softwedge -c /dev/ttyUSB0 -f
softwedge not daemonizing...

X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 101 (X_GetKeyboardMapping)
Value in failed request: 0x0
Serial number of failed request: 20
Current serial number in output stream: 20

I found only this discussion about this error: https://bugs.freedesktop.org/show_bug.cgi?id=12538

I checked directory /usr/share/X11/xkb/keycodes. All files has value of parameter "maximum" set to 255 except file "sun". So I set value from 132 to 255, but it didn't help.
