Windows 7: USB ports dont work anymore on my HP Dv6 laptop

USB ports dont work anymore on my HP Dv6 laptop

Out of nowhere!
I first noticed my Blackberry wasnt syncronizing automatically as it used to, after I upgraded to BB 6.0. I tried the portable HDD which didnt do anything and no flashdrives were regognized.
I tried to uninstall BB6.0 (unsuccessfuly) It froze. Just coulndt do it.
When trying to install BB5.1 from a CD, it didnt want to autorun, although the CD was turning.
I followed a thread to get the DVD working by toggling the autorun option and installed BB 5.1. I couldnt sync, though as none of the USB is working. Stragely my logitech mouse works. It seems that if a device is connected in the USB before I start up the machine it works OK, when inserted after start-up it doesnt work.
I have tried MS Fix it for hardware devices and it has been running for 4 hrs "resolving" problems. I suspect its not working.
What can I do?
(Win 7 does not shut down normally when I have connected to the office network. For some reason it "shutting down" never does. On the home network it shuts down normally)

If the port drivers are corrupted eg usbport.sys. They may be repaired with this command
SFC /SCANNOW Command - System File Checker

I can find them. Do you think a mere re-install of windows 7 will solve this issue?

Not that big a deal. I am thinking of a repair install

I do not know what is causing this issue. If it is hardware you have to actually have someone work on it.

If software this may work.

Switch off PSU
Pull the power plug/mains lead right out of the socket.
Pull all usb leads/receivers out - except for mouse/keyboard
Remove battery from a laptop!

Leave without any power source for a couple of minutes.

Reattach battery for a laptop.
Reattach Power lead,

USB chip will be reset and OS(WIN7/XP etc) will hunt for any new USB connections automatically (as long as you haven't fiddled/turned anything off in 'Services'.)

Thanks thefabe

Just like to add that many esp. laptop motherboard USB ports do actually die. Could be a solder break/haircrack.
Usually one, then another!

There usually is no solution other than to try to replace the motherboard which the original manufacturer will sting you with about half to 2/3rds the cost of a brand new laptop.

Or get a magnifying glass + multimeter + solder kit out.

Hi there
+1 for you because --although a different topic completely your method worked.

I had a Nokia X6 phone which W7 refused totally to recognize even using the Nokia dedicated data usb cable. Using bluetooth to transfer music files to the phone was slow and tedious (phone has internal 16 GB memory so can get a decent amount of music files on it).

Used your method --guess what on next boot computer said found new hardware etc etc and found the phone.

Cheers
