[sane-devel] [patch][RFC] sanei_usb_init improvement

[stef]

	Hello,

	you can test easily the patch with the following program run with 
SANE_DEBUG_SANEI_USB=6 :

#include <stdlib.h>
#include <string.h>
#include <check.h>

/* sane includes for the sanei functions called */
#include "../include/sane/sane.h"
#include "../include/sane/saneopts.h"
#include "../include/sane/sanei.h"
#include "../include/sane/sanei_usb.h"

int main(int argc, char **argv)
{
	while(1)
	{
		sanei_usb_init();
		printf("=============================\n");
		sleep(2);
	}
}

gcc -ggdb usb_init_test.c -I../include -o 
usb_init_test -L../sanei -lsanei -lusb

	Then plug/replug scanners to check that the device list remains consistent.

Regards,
	Stef
