SOURCE: Computer not recognizing any usb devices

Well, appears that your configuration can handle 4 GB of memory. I checked the Acer website for upgrades for your model, and nothing appears to jump out which could solve your problem. A few appear to be possibly helpful, but some are for XP, not Vista. Upgrading "launch manager" might be a good thing.

However, Belarc tells me that on my Acer 5630 i have listed under "Bus adapters" the following:
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C8
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C9
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CA
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CB
Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC
And, under "other devices", i have a USB Root Hub (5x). Obviously, the two match. I go to device manager to check them out, finding them under 'univesal bus controllers", to see whether they are all working properly, and and they are. In addition, opening "system devices" reveals something called a "plug and play software device enumerator", and that checks out to be working fine as well. Check your equivalent out to see if you find a problem to fix. Hopefully you will. Let me know how things go.

I would manually un-install, and then reboot so the system could re-install. Also do a complete system virus scan, just to be sure
that a bug isn't operating.

Testimonial: "Downloading all updates from Windows and Dell did not solve the problem, but uninstall and reboot did. On reboot it reinstalled itself by finding the drivers previously downloaded."

SOURCE: Acer Aspire 5820T Pc Notebook - Its not detecting the usb drivers. No usb ports work and neither does the Web Cam. Showing as Unknown Device under the usb devices.

I would guess the drivers are either not installed, or the wrong ones are installed. Go to the Acer website and select your model and download the current drivers from there and install.

All usb devices unknown

They forgot to install the chipset drivers for the motherboard. You need to go to acer's support site and search for the chipset driver download for your model and install it.

I have hp dv6's annoying because ''windows explorer usb device not recognized'' keep popping up..i already did uninstall the ''unknown device'' in...

let me understand this
this is not post , saying that and unstated USB device is dead
but is Phantom device. you dont want.

That is PNP
why not unplug all USB devices, then put them all back in 1by 1 to see which one is the problem child.
then get the correct driver, from HP or from the maker of the device that is failing.
there is no other way, (be connected to the web if on PnP will be near brain dead.)
are you, connected?

if say a DV6xxxxx (what is the full model number)
say there is no USB plugged in at all, that means hardware failure
deep in the MOBO
or is missing base line HP USB chip drivers missing or mangled.
this would be a true phantom, no USB devices there.
and is bad USB chip drivers for your unstated DV6
there are many DV6s and not all DV6s use the same chips
so........ see here.

see a real service tag,, to get help at
they will demand that funny 4 digits at the red arrow and us
us means for USA> as we to have special chips, .
the below is (sanitized,neutered)

DV5 example.
if posting to id say my DV6-1234us was messed up.
1234 i just made up.
