Since we now have the possibility to change the endpoint used for a particular USB communication type,
we also need a way to retrieve the current endpoint, so that one can e.g. reset the endpoint to the
old value after a single usb operation on a different endpoint.
Added
void sanei_usb_set_endpoint (SANE_Int dn, SANE_Int ep_type, SANE_Int ep);
This function allows the user to set the endpoint to use on
the given device for the given endpoint type (e.g. bulk in).
Some scanners have multiple bulk in/out endpoints but use
only one for communication (not the one detected during auto-detection),
so one call to the new function will change the used endpoint.
Some scanners use two different endpoint for different purposes,
so in that case each read/write call needs to be preceeded
by a call to that function to set the proper endpoint.
ep_type is a bitmask and is usually of the form
(USB_DIR_IN|USB_ENDPOINT_TYPE_BULK)
This commit adds some debug verbosity to the last committed sanei_usb.c patch
id 5b69fa8c6d
for fixing the choice of usb endpoints, in the sanei_usb_open() seek for endpoints loop.
Updated following files for Pixma MP730 support:
- backend/pixma_mp730.c:
Add width scan area fitting
Fix end scan sequence protocol
- sanei/sanei_usb.c:
In sanei_usb_open(), changed the "seek for endpoints" loop
so that it first looks for those interfaces (in config 0)
that have been detected as potential scanners in
sanei_usb_init()
patches have been applied yet, but it's a start. The backends
are not installed as shared libs but as add-ons, which are shared libs
but in a specific folder in [/system|~]/config/add-ons/ named SANE/.
The install target has been changed to account for this,
Some files don't exist in BeOS/ZETA (ipc.h, ...).
Bbackend function names get a prefix, I suppose to avoid namespace clashes.
Though we do have a libdl to implement dl_open, the native way is prefered.
Added a --with-docdir= configure arg.
BeOS has a broken get[name|addr]info() from bind. This is fixed in ZETA R1.
libtool needs -no-undefined. Various VPATH fixes.
Check for <be/drivers/USB_scanner.h>, but not used yet.
No S_IFSOCK (sockets are fds to /dev/net/api). Stub pio code, untested.

* sanei/sanei_usb.c configure.in: use usb_interrupt_read instead of
usb_bulk_read for sanei_usb_read_int. Fixes bug #300878. Added a missing DBG output in sanei_usb_read_int. Check for
usb_interrupt_read to make sure, we have at least version 0.1.8.

sanei_usb_find_devices is called. Also only devices that really exist are
opened. These changes fixe the slow detection of devices on systems using
devfs or old scanner drivers.
interface number from bInterfaceNumber. Explicitely set the alternative
setting. When closing, call clear_halt, and reset_ep, and release_interface
explicitley. On errors in write/read, call clear_halt.
