Here are minimal usb_find_interface() patches for the core, usblp and
scanner.

Basic design is:
- device major (USB_MAJOR for now) and minor are stored in probe()
   function to struct usb_interface as kdev_t
- open() can use new core function usb_find_interface() to find matching
  device in drivers device list
- disconnect() will set kdev_t struct usb_interface to NODEV, so open
  wont open it anymore without new probe()

I tested these patches and they work for me. I will work on small patches
of other work in these drivers (like removal of lock_kernel/unlock_kernel
in usblp, fixing the disconnect problems in both drivers etc.). Those
patches would be very small too, but there will be quite many.

Thanks to Pat Mochel for pointing this out to me.

This means that all individual usb-serial ports show up as their
own devices in the driver model tree.

sorry to bother you again - now that 2.4.20 is out, is there any
chance to include this in 2.4.21?  I've been trying since 2.4.19,
a few other UNUSUAL_DEV entries were added, but not this one...

The device works fine with the patch (and doesn't work at all without
it) for me and a few other people (devices with different "marketing"
names, the same vendor:device id), no one has reported any problems.
The patch has been in the 2.4-ac tree for a while, too.

I was getting annoyed that nobody fixed the obviously broken
debounce loop, so I had to go ahead and fix that.

* 5704-A0 chip-specific patch. fixes PXE issue.
* the existence of the mini ring is an urban legend.
  (no production board has it; it requires external SRAM)
* re-arrange driver-private struct to be cacheline-friendly.

- Finalized the interface by :

        * Having an epoll_event structure instead of using the pollfd
        * Adding a 64 bit opaque data member to the epoll_event structure
        * Removing the "fd" member from the epoll_event structure
        * Removing the "revents" member to leave space for a unique 32 bit
                "events" member

- Fixes the problem where, due the new callback'd wake_up() mechanism
        loops might be generated by bringing deadlock or stack blow ups.
        In fact a user could create a cycle by adding epoll fds inside
        other epoll fds. The patch solves the problem by either :

        * Moving the wake_up() call done on the poll wait queue head,
                outside the locked region
        * Implementing a new safe wake up function for the poll wait queue
                head

- Some variable renaming

- Changed __NR_sys_epoll_* to __NR_epoll_* ( Hanna Linder )

- Blocked the add operation of an epoll file descriptor inside itself

- Comments added/fixed

New NVIDIA and Radeon cards pci ids. Soon I will add support for these :-) Also a needed fix for fbcon.c.

Here's a small patch for the file. The patch is against 2.5.50.

This patch makes ss->ep_int just like ep_in and ep_out for improved code
symmetry and readability.  It may (on some architectures) also shrink the
size of the per-device data structure.

Change interrupt used for CBI from periodic to one-shot.  This (a) reduces
consumed bandwidth, (b) makes the logic clearer, and (c) makes the abort
mechanism more uniform.

While in search of a different bug, I found this one
that got in with the recent 'async_next' patch.  The
schedule scan termination changed (had to), but it
wasn't quite correct.  Slower and/or misbehaving
devices might have wedged a CPU ... fix is simple,
only restart the scan when the list may have changed.
