wide:0 is surely necessary because of the UW-Chip on the adapter. My first
thought was, that the handshaking to UW was performed, so the narrow
connection would block further transfers. Either the wide:0 does not work
for some reason, or the U-to-UW adapter is crap. Maybe you can try
switching off ultra speed and see if it works then:
loadlin... ncr53c8xx=wide:0,ultra=n ...

I'm not sure if the driver should report the disabled wide mode here.
