I'm absolutelly new to write USB drivers, please help me how to start.
I want to write driver a USB to Serial (RS232) converter. I have the
Linux source.
But haven't got the point where to start. I know it is a USB based
driver (IOUSBDevice?) and at the same time it is a UNIX char device (
/dev/tty.myport ). How can I connect these two "parts" together? May I
separate them into two ones: a kernel part which handles USB device and
a user part which handles the communication to the UNIX dev point.
It's so confusing me, so please help me where to go ...
Thanks in advance,
Gabor
