Hello,
I have pushed the sanei_usb improvements:
- now there is a sanei_usb_exit() that frees resources allocated by
sanei_usb_ini()t
- instead of calling sanei_usb_init() each time we want to have an
updated USB device list, we can call the sanei_usb_scan_devices() function
The typical workflow of a backend using USB is now:
- call sanei_usb_init() in sane_init()
- call sanei_usb_scan_devices() each time sane_get_devices() is
called to have an up-to-date list of USB scanners
- call sanei_usb_exit() in sane_exit() to free resources
There are now several test programs in testsuite/sanei to test
sanei_* functions. They are run through the 'check' target (e.g. 'make
check'). The test_wire.c test program has been moved from sanei to this
new sub directory.
Regards,
Stef
