Fixed bugs reported by csp@andrew.cmu.edu. The bug report was as follows:
I have been attempting to get a NI-ATAO10, a 10 channel legacy ISA analog output
board, working with comedi. Apparantely the way comedi_from_phys works to
convert voltage to sample doesn't seem to work correctly with the ATAO10 board.
I found that the correct sample data for the ATAO10 board is as follows:
In unipolar mode
0V = 2048
+10V = 6143
In bipolar mode
-10V = 2048
+10V = 6143
It seems that comedi_from_phys is somehow shifted by 2048 from what it should be
(comedi_from_phys gives values from 0 to 4095).
Furthermore, comedi does not detect the polarity of the board (I'm not sure if
this is possible on this board); thus the range is always reported as -10V to
+10V even if the board is set on unipolar mode (which is achieved by setting
jumpers on the board).
Finally, for some reason, channel 0 does not work with Comedi (the board fully
works in Windows). The other 9 channels work.

The submission of the bulk transfers can be delayed. This leads in the worst case to a change in the order of bulk transfers. For example, the insn command requests the counter value. After that another insn requests the status of the digital port. It happens that these requests are swapped in their temporal order because the USB controller might delay a submission because of heavy traffic. The linux kernel _assumes_ that the packet has been sent. In fact this can't be guaranteed. Therefore now the packet which is sent from the firmware is checked. If it is the wrong one it is requested again.
