* - Fixed USBtoSerial and XPLAINBridge demos discarding data from the PC if the send buffer becomes full
* - Fixed broken input in the MagStripe reader project due to an incorrect HID report descriptor
* - Fixed incorrect PollingIntervalMS values in the demo/project/bootloader endpoint descriptors (thanks to MCS Electronics)
+ * - Fixed AVRISP-MKII clone project not starting the target's program automatically after exiting TPI programming mode
