Exactly.

True, but a once over wouldn't have hurt.  Corrections for mis-comments
and wrong argument types would have been nice.  Error handling is a
secondary consideration for sample code.

I have to assume that the sample code does the generic basics.  Are you
saying that I can expect problems with this code like I did when I tried
to get the interface description?  I would have thought these to be all
part of the generic functions.

I'm going to work on upgrading to snv_28.  I've been told that there
were a few usb patches since snv_18.  With luck, all my issues will have
disappeared.

Thanks for replying, Frits.  If I keep banging on this long enough, I'll
probably start understanding it.

Gary
