    USB descriptor doesn't care about bits, it deals in bytes.

    10 bits will take 2 bytes from PBP (word). You can move high and low bytes individually from word into 2 bytes in descriptor.

    Look how big your descriptor area is in your current USB examples. You have to make sure you have enough pairs of bytes (8 axis needs 16 bytes).

    Once on the PC, I can't say how to convert the 2 bytes to a value.
