* Prolific PL-2301/PL-2302 driver ... http://www.prolific.com.tw/
*
* The protocol and handshaking used here should be bug-compatible
* with the Linux 2.2 "plusb" driver, by Deti Fliegl.
*
* HEADS UP: this handshaking isn't all that robust. This driver
* gets confused easily if you unplug one end of the cable then
* try to connect it again; you'll need to restart both ends. The
* "naplink" software (used by some PlayStation/2 developers) does
* the handshaking much better! Also, sometimes this hardware
* seems to get wedged under load. Prolific docs are weak, and
* don't identify differences between PL2301 and PL2302, much less
* anything to explain the different PL2302 versions observed.
*
* NOTE: pl2501 has several modes, including pl2301 and pl2302
* compatibility. Some docs suggest the difference between 2301
* and 2302 is only to make MS-Windows use a different driver...
*
* pl25a1 glue based on patch from Tony Gibbs. Prolific "docs" on
* this chip are as usual incomplete about what control messages
* are supported.
