Removed Frank's memleak fix. The memory is allocated only once in
...
sanei_usb_init, not in sanei_usb_open. So releasing it in sanei_usb_close
breaks backends that open devices more than once.

Support for interrupt endpoint reads:
...
/** Initiate a interrupt transfer read.
*
* Read up to size bytes from the interrupt endpoint from the device to
* buffer. After the read, size contains the number of bytes actually read.
*
* @param dn device number
* @param buffer buffer to store read data in
* @param size size of the data
*
* @return
* - SANE_STATUS_GOOD - on succes
* - SANE_STATUS_EOF - if zero bytes have been read
* - SANE_STATUS_IO_ERROR - if an error occured during the read
* - SANE_STATUS_INVAL - on every other error

Scanning for devices is now done in sanei_usb_init instead of every time when
...
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.

Explicitely set first configuration. When claiming the interface, use the

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.

Made buffer const SANE_Byte * in sanei_usb_bulk_write(). Try to call

usb_find_busses only once. Make sure that already opened devices aren't opened
