Attaching two USB scanners to a PC
Asked by dearnold in Computer Scanners
Tags: scanners, two, one
The Epson is plugged directly to the PC. The Xerox is plugged into a USB hub.
I wrote to Epson Tech support. They suggested reinstalling the driver; made sense. But, it did absolutely no good. When I wrote back to tell them about that (and I've also told them the brand, etc, of the other scanner), this is the response I got:
>>>>Thank you for contacting the Epson Connection.
You may not be able to install multiple Universal Serial Bus (USB) scanners in Windows XP and use them simultaneously. For example, when you attach two scanners to the Universal Serial Bus (USB) ports of your Windows XP-based computer, the first scanner that you connect is detected correctly; however, when you connect the second scanner, you may experience one of the following symptoms:
A) The second scanner is listed in Device Manager as "Unknown Device".
B) You receive the following error message (it is displayed next to the scanner in Device Manager):
Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)
This occurs because the Usbscan.sys driver cannot be used simultaneously by more than one scanner. To work around this, connect and use one scanner at a time. To use the second scanner, disconnect the first scanner from the USB port, restart the computer, and then connect the second scanner. To use the first scanner, disconnect the second scanner from the USB port, restart the computer, and then connect the first scanner.<<<<<<<<<<
I don't have any error messages or "Unknown Devices" in Device Manager. And, it's hard to believe that Win XP can't handle two scanners. Any advice?
Thanks.
