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? >Even stranger is that occasionally I have to install/uninstall the >scanner drivers several times before the scanner is recognize 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. >The shutdown sequence seems to go normally but it will >not power down 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. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of James L.

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. > >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] Behalf Of James L.

The Epson scanner also has a SCSI interface. Maybe using it would help. I haven't done that because the scanner has a 50-pin connector and my Adaptec SCSI card has a 25-pin connector - I guess there's such a thing as an adapter. > >Any advice would be greatly appreciated. > >Jim Sims > > > > ---------------------------------------------------------------------------- ------------ Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body --- Incoming mail is certified Virus Free.
