From 1a448db77b10153703bc5e4ad13dd55d88beb1d6 Mon Sep 17 00:00:00 2001 From: Bryan Wu Date: Sun, 18 Jan 2009 23:04:27 -0500 Subject: [PATCH] usb_scan_devices: fix output with no devices We should check the return of usb_new_device() so that if no USB device is found, we print out the right message rather than always saying "new usb device found".
