This evening, I wrote a very preliminary implementation of
the MODULE_DEVICE_TABLE support for parport. I have added the
necessary kernel code, made the changes to depmod, and written
a simple program that lists the modules corresonding to a particular
device ID string. Having the program read the ID string either
via an ioctl (for USB) or reading /proc/sys/devices/parport is
easy enough, although it is dependent on whether or not
we continue to "parse" the USB device ID information in
/proc/sys/devices/parport or will provide the raw data.
Currently, there are a couple of kludges in my approach
that I should probably fix. First of all, struct parport_device_id
holds a single character (the array of structs is actually the
string being matched). Secondly, the code is depmod uses some
misleading variable names because of the struct to char conversion.
I expect to post patches tomorrow. So, if you have any
requests about how this should look, please let me know right away.
Also, any IEEE-1284 device ID's for non-printer devices would
