I have had a problem for so long I don't remember when it began. Whenever I reboot for whatever reason the hardware "finder" wizard ALWAYS comes up to load some unknown device. If I pursue to see what it's trying to load I will get messages like so: "VID_04E6PID_80000002. Type: Other devices. Mfr: Unknown. Location: LPT1.0." Another one is "Device type: Other devices. Mfr: Unknown. Location: on USB Printing Support." I've seen it ask for an *.inf file/driver when I push to the end, but what inf file is never made known no matter what CD I put in the tray or how it searches the hard drive. It's nuts.
I ALWAYS get a message in the box (on any and all) that "this device is working properly"!!! ???
My Logitech mouse, HP scanner 5370C, Iomega CD Predator burner, HP Printer 1220cse, and digital camera (when I need to download images) are all accounted for and have no conflicts, working perfectly.
I have a USB hub which is connected to the USB port on the computer. The CD burner is also directly connected to the computer USB port. Everything else I have mentioned is connected to the USB Hub itself. Broderbund PDF creator shows LPT1 as its printer (good luck, fella, it ain't there!). I've never had occasion to use that program. I just got Adobe Acrobat for desktop work, and I bet it will find it's "printer" too and it best choose the USB port! The video is fine and sure is not on LPT1! Each peripheral is accounted for and is working perfectly.
This "unknown" item(s) totally flummox me. I go in and uninstall to get it off, but it always comes back even when I cancel out that wizard that pops up on reboot.
This is a big mystery to me. Ask me what you need to know before I belabor this too much.
