Degug Console

hid_listen can't find device

When debug console of your device is not ready you will see like this:

Waiting for device:.........

once the device is pluged in then hid_listen finds it you will get this message:

Waiting for new device:.........................
Listening:

Check if you can't get this 'Listening:' message:

• build with CONSOLE_ENABLE=yes in Makefile.

Can't get message from console

Check:

• connect the device to hid_listen. See above.
• push LShift+RShift+d to enable debug. See Magic Commands.
• set debug_enable=yes usually in matrix_init() in matrix.c.
• try using 'print' function instead of debug print. See common/print.h.
• disconnect other devices with console function. See Issue #97.
