We have several HP ScanJet 7400c scanners attached to Dell workstations (Dimension 3000) with XP Pro.  When our users try to scan they get a dialog box that looks like the attached jpg.   Our users have to click on Retry every page.   In doing some research, it looks like it might be that USB ports don't like sharing IRQ's and on these systems they are sharing IRQ 16.  In addition, ACPI (?) will not let me manually assign an IRQ even though IRQ 22 is available after I disabled the modem (not needed).

Switch To ... Retry...Error while scanning

A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor). These auxiliary devices are intended to be connected to the computer and used in conjunction with it. Examples of external peripherals include mouse, keyboard, printer, monitor, external Zip drive or scanner, while internal peripherals include CD-ROM drive, CD-R drive or internal modem. Today's new devices, such as tablets, smartphones and wearable computing devices are considered peripherals as they can be connected and used on a computer system. The difference, however, is that these devices can run independently of the computer system.

Peripherals

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

System Utilities are a type of system software used to support the computer infrastructure, distinguishing it from application software which is aimed at directly performing tasks that benefit ordinary users. Commonly used utilities include password managers, disk managers, system monitors, data synchronization tools, security and antivirus software and editors.
