    USB Emulation in BIOS

    Hi, I've been having a problem with my PC for a while and finally decided to try to sort it out. It will not boot when my printer is plugged in (Lexmark X3650), it just freezes at the splash screen. It's really annoying to have to unplug the printer every time I reboot the PC. I have googled the hell out of this and can't get a sensible answer, so I was hoping someone on here may know.

    Things I have tried:
    -using different port
    -using different cable
    -reinstalling printer
    -Updating BIOS
    -Changing boot priority
    -Unsuring HD has priority over USB boot

    The only thing that seems to work is turning USB emulation off. If I leave it off are there any disadvantages (it was on by default). I don't know a great deal about what it does exactly, only that it assigns USB memory cards below/above 530MB as floppy drives/hard drives respectively. What it actually does in practical everyday use I have no idea. Will it prevent me from doing anything? Or is it likely to cause problems when using other device? Is there a better way of sorting this?
    Any help appreciated, many thanks.

    usb emulation is so you can use a usb keyboard/mouse in things outside of windows
    such as setting up windows when you install it

    Does it boot with plugged in printer from a bootable CD?

    So there is no really problem day-to-day and I could just use a PS2 keyboard for other things?

    I don't know, haven't tried. Don't think I have a bootable CD around either. If it does, what then?

    I have a lexmark X5470 that won't let the computer boot on startup. Tried it on two computers, it's a lexmark problem.

    Leaving emulation off will just stop you using your keyboard and mouse in DOS for any DOS programs. Windows installation CD uses it's own drivers so should be fine.

    yes, I keep a ps2 keyboard (well my keyboard is usb and can use a ps2 adaptor) for setting up windows, many pc's i come across wont work with usb in setting up windows, even a brand new machine!

    all is well if you have ps2 stuff around, so if it works for you. then problem solved
