   *  - 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 PDI/TPI programming speed of ~250KHz in the AVRISP-MKII Clone project, instead of the desired 500KHz
