[sane-devel] [PATCH] sanei usb improvements

[Stef]

     Hello,

     here is a cleaned-up patchset that splits device scanning logic 
from sanei_usb_init(),
add a sanei_usb_exit() to free allocated resources. I also brings some 
fixes and improvements. It also add a test program to test the changes done:

0001-split-device-scanning-logic-from-sanei_usb_init.patch :
     split device scanning from init in a new sanei_usb_scan_devices(). 
This function is still called by sanei_usb_init() to preserve current 
behaviour. sanei_usb_scan_devices() is split in smaller functions 
(instead a big one) dedicated to a particular scanning method.

0008-rewrite-sanei_usb_get_vendor_product-rewrite-sanei_u.patch :

0009-fix-memleak-when-reusing-an-already-stored-device.patch :
     fix a memleak when not storing an already detected device.

0010-don-t-use-kernel-device-when-libusb-is-available.patch :
