Hi,
I have a device (thermal printer) which communicates through rs232. It
has also usb adapter/converter build-in.

After 'modprobe usbserial vendor=0x1a28 product=0x6010' the device is
working, /dev/ttyUSB0 pops out. I can read and write to /dev/ttyUSB0 and
it responds.

Above output from dmesg suggests, that I should report it on this
mailing list. I am using debian jessie/sid with 3.12-1-686-pae kernel.
I have just one problem with that device. This is typical response from
the printer:
1#X0;0;0;1;1;1;14;02;05/23.00/08.00/00.00/05.00/17/0.00/0.001`/0.00/0.00/0.00/284.00/BCM11034990
and this "1`" inside is strange, so I investigated further:
emanuel@emanuel-laptop:~$ cat /dev/ttyUSB0
1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`1`^C
What can I do with that? Is it becouse the generic driver?
Regards,
Emanuel
