Dear,

I solve it on my debian and mageia.

I replace in the line 2332 and 2363 in ch343.c

ASYNCB_INITIALIZED => tty_port_initialized

Best regards,
Stéphane.

I tried Stéphane's fix, but I got this error message:
ch343.c:2363:15: warning: passing argument 1 of ‘test_bit’ makes integer from pointer without a cast [-Wint-conversion]
