The usual way to correct this is to add a whitelist to override cable
detection. Laptops can be identified using dmi data and add-on cards
hopefully with subsystem. Dang... Addonics didn't set Subsystem.
I don't know very well about CF but does it even fill UDMA/33? What
does 'dd if=/dev/sdc of=/dev/null bs=1M count=16 iflag=direct' say? You
can increase count for more reliable result.
