There's an issue of LPC1768FBD100 that use the USB Host function to communicate with keyboards. The USB Host has a re-try function if the keyboard doesn't feedback to Host that the Host will send request continuously.

The issue only caused while re-try to kenboard for 1 byte. If the communication date is above 2 bytes that the re-try function works fine.
