Hello,
I need to connect 16 USB modems on the same PC. Due to USB tty port mapping
is dynamic, I often don't know which modem has which ttyUSB or ttyACM port.
Therefore, I want to modify the kernel's USB driver to achieve fixed
mapping.
Can anyone point me to any kernel development book webpage on how to
open/read/write to a file in the kernel? I plan to put the fixed port
mapping in a config file and have kernel read from it.
Thanks,
Simon
