Are there any issues with having two scanners on the same system? (i.e.
driver conflicts)

Scanners; Epson flatbed and a HP with ADF

TIA

If both are USB, then there is a good chance of issues, see

If at least one is not USB, then there shouldnt be any issue.

Thanks Wayne... seems this would, (could), be a desired setup on countless
systems. One would think there might be an A/B switch or programming that
could switch between the two devices.

Appreciate the heads-up.

I have an HP ScanJet 6300C and a Nikon LS-2000, both SCSI, happily
co-existing on my system.

Of course.
You could have 7 scanners on a SCSI system.

Yeah, but I wonder how short the SCSI cables would have to be?
Spec says 4.9 feet maximum total Ultra bus length if more than four
devices, so maybe eight inches each for seven? <g>

Length is a big problem for SCSI, and I've always had trouble with more
than two SCSI scanners (with regular cables and some internal stuff).
But I have four scanners on XP (two SCSI, one Firewire, one USB) without
any problem.

yeah, I don't really know.
But I have 4 SCSI devices right now, (CD-R, Jaz drive, LS2000, HPIIcx),
used to have external Zip drive on it also.

And a heck of a alot longer than 5' total. I've got one cable that's
maybe 4 feet alone. I'm guessing maybe 12-14 feet total chain.

And a real hodgepodge of cables/connectors, 50HD, 25pin, and Centronics.

Then again, these are not high speed devices like hard drives either.

That's about my setup too, but I was never able to make three external SCSI
devices work due to cable length. One foot cables are just not very
practical for scanners. <g> With two SCSI scanners, to use an external zip
disk, I have to power down and swap it out with the last scanner to keep the
bus shorter. Even then, an internal CDR stops working if the zip is attached
(I suspect the zip auto termination is not so good).

The Fast and Ultra SCSI bus is rated 3 meters (10 feet) overall, except if
four or more devices are on the Ultra bus, the spec drops to half of that.
Generally they say at least 6 inches spacing between device connectors, which
even approaches a problem for seven internal devices too. But one can have
multiple SCSI cards of course.

SCSI was truly fantastic in its day, I was a big fan. Its coprocessor
multitasking ability was great, and the ability for multiple devices to use
one IRQ was essential because the PC was so limited. But then Windows became
able to share PCI IRQ, and other less fussy interfaces were developed, so
SCSI is fading away now, except perhaps for server disks.
