Looking at the code, there are only two places where "invalid
argument" will be returned. 1) If you have requested an invalid
starting track (below first track or above last track) or 2) You
have given an invalid value in the data_len field of the
ioc_read_toc_entry structure.
I suspect it maybe to do with trying to read the leadout
track. Xcdplayer reads each track's TOC entry one by one rather than
the whole lot at once. So the lead out track is read using a
starting track of 0xaa which is above the last valid track and the
driver barfs. I'll have to try this out, but I am pretty sure this
is the problem.
BTW I am looking at 2.1.5R sources here.
