Never mind. I realized three things:

a) my 53c400 card must be initialized first by DOS driver to be detected by Linux kernel

b) The scanner initialization lasts about 4 minutes. And scanning is very slow
even if I increase the kernel buffer to the max. as described in the SANE doc.

c) Using an adaptec SCSI adapter works just fine: scanner initializes
immediately, card is recognized even without DOS and the scanning is much
faster.

Ok I've not needed that for mine. Must be a variant init function is used on
yours.

That sounds like a bug - takes about 9 seconds for me

Yes - I keep meaning to move mine to a real scsi controller
