Henning Geinitz 8007efa1a3 Enable close_on_exec in sanei_usb_open. 2003-07-17 15:05:14 +00:00
Henning Geinitz 74de40f1da 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.

Frank Zago bce2146bd0 Fixed memleak. 2003-04-19 03:57:06 +00:00
Henning Geinitz 90fa11913c Added a function to print the buffer contents for the read and write 
functions. Fixed some DBGs. Fixed a wrong return value.

Rene Rebe a6858b5057 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
 *

Henning Geinitz 08af36a2e8 Call sanei_usb_init only once. 2003-02-22 15:45:51 +00:00
Henning Geinitz 5d4e2220a0 Check all acceptable interfaces instead of using the first one. 2003-02-19 19:38:26 +00:00
Henning Geinitz b625db341a usb_clear_halt should only be called in libusb mode. 2003-02-18 20:14:08 +00:00
Henning Geinitz c03e019f1c 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.

Henning Geinitz 8ea589819e Don't call usb_clearhalt and usb_set_altinterface to avoid errors on Mac OS X. 2003-01-15 14:27:54 +00:00
Henning Geinitz d2d3aaf90d Comment out resetep at sane_close. This function sets th USB data toggle only 
on the host side.
 2003-01-10 16:44:53 +00:00
Henning Geinitz d9041acb54 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.

Karl Heinz Kremer 574cea3bcb Use endpoint address with directional information instead of just the 
endpoint reference. This caused problems on Darwin systems.

Henning Geinitz a99e4f1ecd Really check for bulk_out ep when writing. 2002-10-15 08:42:42 +00:00
Henning Geinitz 433a923082 Made libusb_timeout static. 2002-07-27 20:33:18 +00:00
Henning Geinitz d9b5733f67 Check if file is already closed.

Henning Geinitz 278709d3d4 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
again. Exit libusb scan loop if one device is found. Make error values more
expressive. Check for missing config descriptors before using them to avoid
segfaults.

confusion. Updated doxygen documentation.
