This makes me think the problem is that the scanner is basically a SCSI
based scanner which uses a USB port but feeds to a SCSI driver. The driver
that goes away may be the SCSI driver. The way that SCSI devices with SCSI
cards work the card is recognized before the OS and the scanner is
recognized only if it is turned on and connected to the card at boot up
before the OS loads. If this is not the case one has to turn the SCSI
device one and go to device manager and refresh and rescan for devices after
the OS loads. This may be the same for USB connected internal SCSI devices
as well. Have you tried rescanning for new deviced in device manager to fine
the scanner after it has disappeared?

This is common for SCSI scanners which often need to be reinstalled up to 8
times in succession without any uninstalling of them before they are
recognized by the OS. This makes me think the problem is that the scanner
is basically a SCSI based scanner which uses a USB port but feeds to a SCSI
driver. There were some older parallel port devices that internally were
SCSI devices and used SCSI drivers but required a parallel port driver as
well so that they could be ported to the parallel port and then to the SCSI
driver. Your scanner may be along those lines except it uses a USB port and
USB mini-driver instead of the parallel port min-driver employed by the
older devices. It is possible that this is confusing you OS or producing
some sort of conflict. Try installing the SCSI driver for this scaanner
along with the USB and see if that helps.

Somehow and for some reason your scanner is causing the system to go into
hybernation rather than shut down. Do you turn the scanner's power off
before shutting the system down? If not, the system may still see the
scanner as beign in use and is reverting to hybernation rather than shut
down.

Laurie,
I almost always have only one scanner turned on. I have each USB device
in its own port - Epson scanner, Epson printer, trackball, and
multi-card reader (that takes up two ports). I have tried switching
ports (a suggestion made by Epson). What's strange is that the only
device drivers that go away are the Epson scanner drivers.
Even stranger is that occasionally I have to install/uninstall the
scanner drivers several times before the scanner is recognized. Another
anomaly is that the computer will often not power down after I use the
Epson Scanner. The shutdown sequence seems to go normally but it will
not power down - screen goes dark, hard drives spool down, but the fans
and power light stay on.

Others have said that they have run into a similar thing with a SCI card
where one of the scanners insisted on being given a specific ID assignment
on the SCSI card or on the card being put into a specifc slot on the
motherboard. Maybe a similar thing is taking place where the two scanner
drivers are in conflict due to the way they load. If one keeps the Polaroid
turned off, doe the Epson continue to lose its driver recognition? It might
also be a conflict between the other USB devices and the scanner. I assume
that all the USB devices are plugged into their own ports on the motherboard
or they are all plugged into a powered hub.
