Windows 7 ne prepoznaje ni jedan USB uređaj

[gordan84]

Windows 7 ne prepoznaje niti jedan usb stik. Izgleda da fali drajver za Mass storage. Probao sam instalirati čipset drajvere za ploču ali nije pomoglo.

Kako da ovo riješim bez reinstalacije?

Probaj ovo:

General USB problems
After a USB device is installed and then removed Windows hides the driver this first part makes all hidden drivers visible.
Remove all USB devices
Click on start orb, Type Advanced System settings in the search box and click to go there.
Click on Advanced tab, Click on Enviroment Variables.
Under the window System variables click on New.
Type " devmgr_show_nonpresent_devices" (without the ") as the variable name and type 1 as the value.
Click ok 3 times to close the windows
Click on start orb, Type Device Manager in the search box and click to go there.
Click on View, Click on Show hidden devices.
Now you can uninstall all old and unknown USB devices. I think it will be best if you uninstall all USB devices
The infcache.1 file is used to store information about USB drivers, the information in this file may have become corrupted or may cause windows to load the wrong driver or cause a driver not found message to be generated.
Deleting this file will force windows to generate a new infcache.1 file
Right click on the start orb and select Windows Explorer,
Select Computer in the address bar and search for infcache.1
Right click on the file infcache.1 (if you have more instances of Windows installed only do this for infcache.1 C:\Windows\System32\Driver Store)
Click on properties, Click on security tab, Click on Edit, Click on Add
Type Administrators In the window with the blinking cursor, Click OK
Place a tick in the box under allow to the right of Full Control, Click Apply, Yes and OK
Delete the infcache.1 file
Connect a USB device, but not the one you were having trouble with to make a new infcache .1
New Start the PC and try your device again.

To je untouched instalacija Win7?

Da, nedirnuta verzija windowsa, ništa čačkano.

@peja
prije nego sam napisao poruku probao sam tu proceduru ali samo do "Deleting this file will force windows to generate a new infcache.1 file".
Onda nisam mogao naći taj fajl koji se dalje spominje pa sam restartovao komp i za trenutak se pojavio jedan već umetnuti stik i pomislio sam to je to; međutim izbacilo mi je obavještenje da nije instaliran drajver za mass storage.

Probaću ipak do kraja odraditi gornju proceduru.
