* - Fixed broken HID_REQ_GetReport request handler in the Low Level GenericHID demo
* - Fixed possible lost data in the XPLAINBridge, USBtoSerial and Benito projects when the host exceeds the packet
* timeout period on received packets as set by USB_STREAM_TIMEOUT_MS (thanks to Justin Rajewski)
* - Fixed possible programming problem in the AVRISP-MKII clone project when programming specific patterns into a target
