This does more specific sub-vendor/sub-product matching, so please
give it a shot. We often find that there are other products that
don't have the high speed clock, as in the original ones people showed
us; your diff would have fed those a high clock.
The way I have been trying to approach this problem is by placing the
more specific mappings ahead of the generic mapping (ie. the generic
mapping does not look at the sub-vendor/sub-product fields). The
generic mapping is then left at the standard slow clock speeds.
I wish there was a better way of knowing the clock speeds. Anyone
seen any clue as to how that might be done?
I find it so strange that puc cards tend to have two serial chips by
different vendors. Perhaps one has a clock generator or some other
pci logic in it, and is more expensive. Shrug.
