New USB HD Unknown Device problem

Hi Guys

Have read through a lot of post, I have similar problem with several threads but I'm more confused now.
I have 3 External HD and one Semi-External (backup unit HP). None of them works through USB ports (none of my 4 ports).
Not even the four different Mem sticks I have tried works.

W7 says unknown devices.
1. I have tried all ports.
2. I have tried on Vista and XP on other machines (no problems).
3. I have had these units working on this hardware before (in vista).
4. I have the latest of everything as it seems.. (I think).
5. I have reinstalled with them plugged in and not like 4 times..
6. I have tried several updates and even tried with old USB drivers..
7. I found a writing on a 4 step check and did that to (power management, uninstall, checking power etc.. )

What the H...

My keyboard works (W-less).. My Camera works.. ? on all ports..

Any one has similar problems ?
This is driving me crazy ..

My Computer is:

HP Pavilion d4492.se
Motherboard:
Motherboard manufacturer's name: ASUS P5LP-LE
HP/Compaq name: Emery-UL8E

All the ports worked in vista and XP ?
so I do not understand .. I have thought of things like "broken" but it does not make sense when keyboard and camera works.. and the disks work on other HW and OS.. also the USB memory stick thing ?

Then it’s also strange about the semi-external disk (I do not know what its called but its a disk in a disk bay or something).. that one is internally connected directly to the main board with some strange cables..
That one is also "unknown" ..

I have followed several threads here, and I'm sorry if I have tried to be in several threads at the same time..

This seems to be a problem different to the others it seems.

ps.
Thanx SQUONKSC to straitening that out for me.. Sorry I’m getting desperate..

So, thousands s3ven x64 users suffer from this damned usb issue. Now it's clear it's bug on OS's side, but so far no patches, fixes or updates. Damn it.

I have exactly same problem described here many times (all drivers are up-to-date, external hdd works on other OS etc but not on windows 7 x64)

Well .. lets hope there will come a patch for it or the full release will have it.. I'm so tired to mount the disks on another machine and access them through the network.. Dah..

sorry i decided to delete post as I thought it may cause a problem, but i guess it would be worth a try, and well no guarantees.

just thought i better add - firstly try restarting the pc after you power it down, and remove all the devices, and try connecting them one at a time if you havent already tried it.

open ur control panel n den go to d option "Accessibility Options" n then click in d option "Configure windows to work for your vision,hearing and mobility need". run d wizard n then restart ur pc n den do all d connection n see if dis works.

plz reply
