I am working with a Dell Desktop that is several years old. It is running XP-Pro SP2. It had an HP6210 all in one installed. The HP6210 was not longer working. I uninstalled the 6210. Rebooted the computer. Installed the HP6310 according to instructions. When I restart the computer with the HP6310 turned on, the computer hangs. I have checked the boot order. The machine is old enough that the only boot device options are the hard drive, the CD-Rom or diskette. I have the hard drive and CD-ROM enabled with the diskette disabled. I still get the same result of the computer hanging until the HP6310 device is turned off. As soon as I turn the HP6310 off, the computer immediately proceeds with the boot process. The only solutions I have seen is disable the USB boot option (which is not an option on this computer). Is there any other solution to this issue other than having the end-user remember to turn off his HP6310 device prior to restarting his computer.
