From 8cb7f6ee8f872938e257541c07d0e4b2ad0e3f35 Mon Sep 17 00:00:00 2001 From: Benjamin Dobell Date: Sun, 17 Jul 2011 19:50:07 +1000 Subject: - Added Utilities tab to Heimdall Frontend. - Fixed Heimdall command line support for PIT files without a reference to themselves. - Added tool tips to Heimdall Frontend. - Added heimdall 'info' and 'download-pit' actions. - Made 'detect' action return 0 if a device is detected, 1 otherwise. --- libusb-1.0/examples/dpfp.c | 508 --------------------------------------------- 1 file changed, 508 deletions(-) delete mode 100644 libusb-1.0/examples/dpfp.c (limited to 'libusb-1.0/examples/dpfp.c') diff --git a/libusb-1.0/examples/dpfp.c b/libusb-1.0/examples/dpfp.c deleted file mode 100644 index 07ffe4d..0000000 --- a/libusb-1.0/examples/dpfp.c +++ /dev/null @@ -1,508 +0,0 @@ -/* - * libusb example program to manipulate U.are.U 4000B fingerprint scanner. - * Copyright (C) 2007 Daniel Drake - * - * Basic image capture program only, does not consider the powerup quirks or - * the fact that image encryption may be enabled.
