Printer disables USB Mass storage device
Posted on 2007-08-07
I have a conflict issue between USB printers and USB mass storage device on our Dell desktop PCs. When the printer is not plugged in, USB mass storage devices can be plugged in and work fine. Once the printer is plugged in, an error pops up saying the 'USB device has malfunctioned'. The printer works fine, but the USB drive no longer works. Within device manager, the mass storage device appears as 'Unknown Device'.
