I am having trouble installing my Epson RX500 all-in-one (printer/scanner/copier) under Windows 2000 via USB 2.0 adapter. Adapter's vendor's website says that "composite" devices require a driver update. Is my printer considered to be a "composite device"?

Here's the definition of what a composite device is: http://www.osr.com/ddk/buses/usbsystem_3ovb.htm

Your printer probably is a composite device.  Here are some troubleshooting tips for USB devices: http://www.usbman.com/Troubleshooter%20General.htm

You probably need to update your USB 2.0 Drivers or download the newest drivers for you Epson

To NWCS: alreadyn downloaded and tried latest Epson driver (see initial post) w/ same problem. Am about to try new USB drivers.
To Callandor: went to the links you provided but still am not sure that my printer is indeed a "composite device"; did not really understand the definition ... too techy for me. ;-(
With this post, all I'm really trying to find out for certain is: "Is my printer considered a 'Composite Device' ?"

Your composite device is probably one of the card readers that is on the printer. When ever i have installed a photo printer with card readers built onto it, they always detect as composit devices. You will have to manually update the driver through device manager and point the hardware wizard to the correct cd location of the card reader drivers or the location of the printer drivers on the.

Here's an easier to understand "picture" of composite devices: http://www.steelbrothers.ch/jusb/docs/chp3-usboverview.pdf

Since you have a printer and a scanner together, that would qualify as a composite device: two or more functions in one.  The example in the link is a webcam and a microphone.
