OK, as its still failing, this means the Read Error bit is still set after it 
reads the transfer buffer size during the link initialisation process. This 
is definitely not right. 

So: either there's some extra wrinkle this CAM needs to work during 
initialisation, or writing to the CAM control register is not working right 
(ala ZetaCAM).

If its the latter, theres not anything we can do, unless either TT fix it, or 
someone happens to know exactly what bits in the JEDEC fusemap for a Lattice 
M4A3-32/32 CPLD do what (the current theory is that its a timing problem when 
writing to IO space on the PC card).

Either way, I think the next step is to wait until you have tested it under 
windows.
