It has been created because all existing ones either operated at a high level (eg. commands to insert breakpoints, which would require a lot of reimplementing existing code), or at a low level (bit-banging GPIO lines, which would be very slow over USB). Instead, the basic commands MehFET operates with, are reads and writes to the IR and DR registers. This is mostly the same abstraction level as used in CMSIS-DAP. ### USB descriptors
