hp scanner 3400c Unknown hardware error
Posted: Thu Mar 16, 2006 2:51 pm
I am trying to get a hp scanner 3400c working for friend and I keep getting the unknown hardware error I used the original disk, then downloaded right from HP then some from driverguide but most of them said unsupported (I'm Using XP Pro) but I also searched for drivers for 98 just to see if they were supported and they weren't either. Changed USB cables to a known good one and no there too. Has anyone else experienced this problem? Or have any more ideas? Thanks.......Melchizedek41
