Weird USB problem after REDHAT

[clarence_3]

Alright I was gonna check out linux redhat 9 the other day, so I went to BIOS and made my computer boot from the cd, then with partition magic 8, I made a linux ext2 partiton on my drive. I then installed redhat via the cd and used GRUB for the boot mode, and everything installed fine, but when I tried to load Redhat my screen would go blank like I had just shut my computer off (green light turned orange), when I looked at the screen on my TV I saw it did load to redhat stratup screen I just couldn't see it on my monitor for some reason. ANyhow to make a long story short I decided to just get rid of Redaht so I went into xp pro and delted the linux partitions (swap, boot and ext) with parttion magic.

then for soem reason when I restarted my computer it wouldn't load into the login screen, it would say GRUB_ and then hang there forever. I couldn't figure out what was wrong and since I had backed up important info onto my external harddrive I decided to just reinstall windows, so I reformated the windows partition (which was the only one I had at the moment) and installed xp pro again. Now here's the weird thing, My USB are not working, I can't recognize my scanner or my external harddrive (which has all my backup stuff including important school stuff) nor will it recognize my key drive which I used to transfer data between my computer and computers at school. I tried uninstalling the USB drivers via the device manager and reinstalling them and that don't work. I don't have a clue what I did to screw things up, but I really, really need some help. If anyone can help me get my USB devices working again I'd appreciate it immensly. Thanks and sorry for the long story.

Oh yeah, I took my external harddrive to school and it worked fine on their PC's there, so it has gotta be a problem with my USB. I had no problems until I tried to install Redhat and now I can't access anything. Its like windows will recognize the USB ports are there it just refuses to acknowledge anything I plug into them. ARGGGGG! its frustrating. Thanks.

Have you tried restting your BIOS, in particular the USB IRQ assignments?

It sounds like they are a bit screwy. If it's finding the USB controllers, but not any devices. . .

What sort of PC hardware are talking about here anyway?

Well, I guess i figured it out. While cruising the device manager I noticed a Question mark icon labeled otehr devices. I opened it and saw I needed to reinsatll the controllers for the USB device. I did that windows searched, found, installed and all my USB devices appeared afterwards. YES! Thanks for your help, though Stuart Browne .
