PCI-MIO6033E timers from Jonathan Wang on 2004-10-05 (gmane.linux.comedi)

I'm using a National Instruments PCI-MIO6033E. Reading their 
documentation, I see that there are 20 MHz and 100 kHz counters on the 
card as well as a frequency scaler. However the Comedi source 
(ni_mio_common.c) appears to only support the 20 MHz frequency. Are 
there any plans to support the frequency scaler or to switch to the 100 
kHz counter? This would be useful as it would open a broader range of 
acquisition frequencies.

Also in ni_mio_common.c, convert_arg is limited to 16 bits although the 
documentation indicates that the card's counters and timers are 24 bits 
wide. The relevant lines are 1523 and 1524 of ni_mio_common.c for 
Comedi release 0.7.68.

Is this correct, or have I found a bug?

Thanks,
Jonathan
