/*
 * The LMM5 USB HID commands are a sequence of binary bytes with no terminator.

 *   USB:    "\x1a\xff\x00\x12" (4 bytes)
 *   RS-232: "1AFF0012\r" (9 bytes)
 * The opposite transformation takes place for the reply.

 * This function abstracts these differences. Note that the exact answerLen is
 * important for USB HID: reading excess bytes can result in garbage being
 * appended to the reply (at least on Windows).
