Hi all !

I have HP ScanJet 3p scanner, that ships with C2502 card.
It works Ok in Windows (both 95 and NT)
The sane HP scanner faq tells that this card is supported by g_NCR5380
I've tried to load g_NCR5380 module with irq and io set to that is
the default in windows:
ncr_irq=5 ncr_addr=0x280 ncr_53C400a=1
but it have not found an adapter.
I also have dtc3181e card that ships with Mustek 1200SP scanner.
This one have been found by g_NCR5380 module in no-irq non-pnp mode
ncr_irq=5 ncr_addr=0x280 dtc_3181=1
But works not perfect. Scanning is very slow, and my system even hung
one time, when I choose too high resolution.
I know that this card has an IRQ in PNP mode but it also don't
initialized by the driver in this mode.

Is Sym53c400A is a better choice than dtc3181e for SANE ?
What i should do to make it work.

There is a fresh copy of RedHat 6.1 (2.2.12-20) on my box, I don't
recompile the kernel yet. So here is the default to RedHat 6.1 SCSI
