From cfc2d0d63246668ae91cfcbb7a7bad63e999ed0a Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 19 Aug 2013 17:17:18 +0200 Subject: [PATCH] usb:dfu:g_dnl: Change number of exported configurations at composite gadget USB composite gadget (g_dnl) supports only one configuration. Due to that the corresponding field - bConfigurationValue has been changed. Moreover more descriptive names were chosen for relevant fields. Windows XP setup: - Thesyscon USB Descriptor Dumper - zadig_xp program for WinUSB installation (which is required by dfu-util) - dfu-util for windows (version 0.6) - TRATS target connected via USB hub to test Win XP machine.
