 * seems to get wedged under load.  Prolific docs are weak, and
46
46
 * don't identify differences between PL2301 and PL2302, much less
47
47
 * anything to explain the different PL2302 versions observed.

 *
 
49
 * NOTE:  pl2501 has several modes, including pl2301 and pl2302
 
50
 * compatibility.   Some docs suggest the difference between 2301
 
51
 * and 2302 is only to make MS-Windows use a different driver...
 
52
 *
 
53
 * pl25a1 glue based on patch from Tony Gibbs.  Prolific "docs" on
 
54
 * this chip are as usual incomplete about what control messages
 
55
 * are supported.
