I'm having a serious problem with a ''USB NOT RECOGNIZED ERROR''
whenever i plug a
usb device into any of the four usb ports on my laptop. This started
happening about a week ago
and i've since being trying all sorts to fix this issue. I'm using a
Fujitsu siemens amilo li 1718
Vista home premium 32 bit
Processor - genuine intel(R) CPU T2130 @1.86 GHz 1.87 GHz
Ram - 1918 Mb
I have tried uninstalling all the USB ports and hub in device manger a
million times and again and again in safe mode.
All the drivers on my mother board are up to date. I have created that
registry hack in the regedit
HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Servic es\Usb -----
'DisableSelectiveSuspend and gave it a value of 1'
Uninstalled all the usb devices in programs and features which was a
total of one. Again reinstalled all usb controllers and Hubs
in device manager. REBooted. Tried plugging in USB devices i have never
used and still no luck.
It was suggested to delete the infcache.1 in windows or rename it to
infcache.bak, rebooted and still the same problem.
I have also tried shutting down my laptop, unplugging the power and
battery and letting it sit over night for two nights in a row but no
Uninstalled windows, deleted everything off the old copy and still the
I downloaded a driver wizard called DRiverWhiz to make sure all drivers
were up to date and scanned the laptop. It came back with a few driver
up to date, like the wireless card and ethernet port which i then
updated through device mgr(not important) but at the very bottom there
was a category called
''unplugged'' Devices (Out of date : 0 ) and under this it showed -
Unknown Device - Port_#0001.Hub_#0003. There is nothing plugged into
this port and this device does not
show up under device manager. I have rebooted several times with
nothing plugged in and this is always the case. When i plug in a usb
device into any port this unplugged device
dissappears in driver whiz and then an unknown device shows under the
USB controllers section. In device manager now there is a unknown
device under usb and when
i unplug the device and scan for new hardware changes the unknown
device stays there and if i unplug the usb and plug it into another usb
port i now get two unknown devices even after
a scan for hardware changes and so on until i ininstall or reboot. If i
uninstall the unknown device in device manager while the usb is
unplugged and then scan new hardware changes
it will reinstall the unknown device untill i reboot.
No viruses either
From the driver whiz help menu i tells me that an unplugged device is
What is an "Unplugged" device?
An "Unplugged" device is any type of plug and play [Wikipedia]
device that is currently not attached to your computer. Devices like
cameras, MP3 players, and USB drives that are
unplugged will show up in "Unplugged Devices" in the Scan Result
You may notice old hardware that has been replaced in your system
in "Unplugged Devices". To fix this problem you will need to install a
registry cleaner [Google].
Ok, so i installed and registered a full version of UNIBLUE registry
booster and scanned the registry, and cleaned all errors but one
remains unfixable everytime i run it,
don't think it's related but will show anyway:
Entry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\cpuz132
Value name: ImagePath
Reason: The value ImagePath in
an invalid path
Not sure what the problem is but if someone can spot something please
let me know...
Thanks in advance
