* Derived from Lego USB Tower driver
* Copyright (C) 2003 David Glance <advidgsf@sourceforge.net>
* 2001-2004 Juergen Stuber <starblue@users.sourceforge.net>
- *
- * V0.1 (mh) Initial version
- * V0.11 (mh) Added raw support for HID 1.0 devices (no interrupt out endpoint)
- * V0.12 (mh) Added kmalloc check for string buffer
- * V0.13 (mh) Added support for LD X-Ray and Machine Test System
