I am looking for a USB scsi adapter. I have found usb adapters that allow you to connect sata and pata devices via usb to a computer. I know that there are usb scsi adapters, but I would like one that will work for multiple types of scsi devices.

The SCSI protocol is much more complex than either the sata or pata
interfaces. It is really *cheaper* to get a PCI scsi controler card
(lots of them on E-Bay).

The discontinued Adaptec USB2Xchange might do what you want.
the dongle side acts as a male HD50 connector, so it's uselss for
attaching to most external devices.
for storage devices, it works fine. For scanners lots of people have
problems.
If you really dig around, there are even firewire to SCSI adapters.

That's what I was going to say: there are USB to SCSI adapters
but they're all abandoned by the mfgr,
so manuals or even working drivers will be hard to find.
geeks.com MIGHT still sell some
but I doubt it supports more than one device
or the full protocol.
I have a Xircom USB "dock" to SCSI, serial port & USB hub,
but it's Mac only. No drivers for Windows or Linux.

If there's a spare slot, a PCI or CardBus/PCMCIA card
would probably be best since most operating systems
still have native support (certainly Linux, BSD),
it'll be cheaper, run at full speed with minimal CPU overhead
and support multiple devices.

USB already does SCSI-2, so the device just has to convert low-levels.
The models that are single device need no drivers.
Some have a switch for single/multiple devices.

True. I think all the laptop solutions are 8-bit though.

In real life, you will find that pass though devices like scanners are
usually not happy on USB to SCSI adapters. It probably has to do with
brittle drivers that come with such devices, but unless you're going to
write your own, you may find they just don't work.
