   - Added 20 MHz module contributed by Jeroen Benschop.
 
 * Release 2008-05-13
-
-  - Fixed bug in libs-host/hiddata.c function usbhidGetReport(): length
-    was not incremented, pointer to length was incremented instead.
-  - Added code to command line tool(s) which claims an interface. This code
-    is disabled by default, but may be necessary on newer Linux kernels.
-  - Added usbconfig.h option "USB_CFG_CHECK_DATA_TOGGLING".
-  - New header "usbportability.h" prepares ports to other development
-    environments.
-  - Long transfers (above 254 bytes) did not work when usbFunctionRead() was
-    used to supply the data. Fixed this bug. [Thanks to Alexander Neumann!]
-  - In hiddata.c (example code for sending/receiving data over HID), use
-    USB_RECIP_DEVICE instead of USB_RECIP_INTERFACE for control transfers so
-    that we need not claim the interface.
-  - in usbPoll() loop 20 times polling for RESET state instead of 10 times.
-    This accounts for the higher clock rates we now support.
-  - Added a module for 12.8 MHz RC oscillator with PLL in receiver loop.
-  - Added hook to SOF code so that oscillator can be tuned to USB frame clock.
-  - Added timeout to waitForJ loop. Helps preventing unexpected hangs.
-  - Added example code for oscillator tuning to libs-device (thanks to
-    Henrik Haftmann for the idea to this routine).
-  - Implemented option USB_CFG_SUPPRESS_INTR_CODE.
-
-* Release 2008-10-22
-
-  - Fixed libs-device/osctune.h: OSCCAL is memory address on ATMega88 and
-    similar, not offset of 0x20 needs to be added.
-  - Allow distribution under GPLv3 for those who have to link against other
-    code distributed under GPLv3.
-
-* Release 2008-11-26
-
-  - Removed libusb-win32 dependency for hid-data example in Makefile.windows.
-    It was never required and confused many people.
-  - Added extern uchar usbRxToken to usbdrv.h.
-  - Integrated a module with CRC checks at 18 MHz by Lukas Schrittwieser.

-General Description:
-This module offers additional functionality for host side drivers based on
-libusb or libusb-win32. It includes a function to find and open a device
-based on numeric IDs and textual description. It also includes a function to
-obtain textual descriptions from a device.
-
-To use this functionality, simply copy opendevice.c and opendevice.h into your
-project and add them to your Makefile. You may modify and redistribute these
-files according to the GNU General Public License (GPL) version 2 or 3.
