+/** @file plustek-usb.c
+ * @brief The interface functions to the USB driver stuff.
+ *
+ * Based on sources acquired from Plustek Inc.<br>
+ * Copyright (C) 2001-2007 Gerhard Jaeger <gerhard@gjaeger.de>
+ *
+ * History:
+ * - 0.40 - starting version of the USB support
+ * - 0.41 - removed CHECK
+ * - added Canon to the manufacturer list
+ * - 0.42 - added warmup stuff
+ * - added setmap function
+ * - changed detection stuff, so we first check whether
+ * - the vendor and product Ids match with the ones in our list
+ * - 0.43 - cleanup
+ * - 0.44 - changes to integration CIS based devices
+ * - 0.45 - added skipFine assignment
+ * - added auto device name detection if only product and vendor id<br>
+ * has been specified
+ * - made 16-bit gray mode work
+ * - added special handling for Genius devices
+ * - added TPA autodetection for EPSON Photo
+ * - fixed bug that causes warmup each time autodetected<br>
+ * TPA on EPSON is used
+ * - removed Genius from PCB-Id check
+ * - added Compaq to the list
+ * - removed the scaler stuff for CIS devices
+ * - removed homeing stuff from readline function
+ * - fixed flag setting in usbDev_startScan()
+ * - 0.46 - added additional branch to support alternate calibration
+ * - 0.47 - added special handling with 0x400 vendor ID and model override
+ * - removed PATH_MAX
+ * - change usbDev_stopScan and usbDev_open prototype
+ * - cleanup
+ * - 0.48 - added function usb_CheckAndCopyAdjs()
+ * - 0.49 - changed autodetection
+ * - added support for LiDE25 (pid 0x2220)
+ * - 0.50 - minor fix for startup reset
+ * removed unnecessary calls to usbio_ResetLM983x()
+ * 1200DPI CIS devices don't use GrayFromColor any longer
+ * - 0.51 - added Syscan to the vendor list
+ * - added SCANFLAG_Calibration handling
+ * - 0.52 - added _WAF_LOFF_ON_START and _WAF_INC_DARKTGT
+ * handling in usbDev_startScan()
+ * added Visioneer
+ * .
