None of the replies so far have offered an explanation of exactly /why/
this doesn't work. Judging from the aiRecord.c code and the format of
the INP link, I venture that the device support indicates to the record
support that it already did the conversion and wrote the VAL field by
returning 2 instead of 0 from its read() method. To teh record support
this indicates that it should completely ignore all conversion related
fields (RVAL, LINR, EGUF, EGUL, ASLO, AOFF, ESLO, EOFF, ROFF).

Cheers
