everything else work normal .. tried system restore , but it didnt fix it..
can't update bios yet, USB can't detect USB flash drive ..
i try to find the manual book, to need learn how to update bios without USB flash drive ..

Hi siryu . These are some things you can troubleshoot with.

Code 10 in windows is rather generic, but I believe the fault lies in the driver for that specific drive.

Before you begin, right click on the "USB Mass Storage Device" in Device Manager with the Yellow Exclamation mark and click "Uninstall" then reboot Windows.

1. Try this fix first and follow these steps:
In Device Manager, click the Driver tab in the device's Properties dialog box.
Click Update Driver to start the Hardware Update Wizard.
Follow the instructions to update the driver.

2. The issue can also be caused by a corruption in the Windows Driver Cache file.

Your windows INFCACHE.1 file can be found in the C:\Windows\System32\DriverStor\ directory.
Right Click on the "INFCACHE.1" file and select "Properties"
Select the "Security" Tab and click the "Edit" button
Click "Add" and in the "Enter Object Names to select" box type the word "Administrator" and click "ok".
Click "Apply" and click "ok" to the Windows Warning Screen.
Once you are back at the "Permissions for INFCACHE.1" window, select "Administrator" and check the "Full -Control" tick box. Click "Apply" and click "YES" to the Windows Warning Screen.
Click "ok" to the rest of the screens until you are back to the location of the "INFCACHE.1" file.
Right Click on the "INFCACHE.1" file and select "Delete". (renaming the file to any other name does not work)
Restart your PC and Windows will rebuild the "INFCACHE.1" file.
Once your PC restarts. Plug in your Integral USB Flash Drive and your device should function as normal.

Other things to try using REGISTRY EDITOR. (backup your registry before you do this).

3. Try deleting the USB "Upper Filter" & "Lower Filter" Entry in Registry.
Open registry editor. REGEDIT
Locate the “UpperFilters” value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
On the “Edit” menu, click “Delete”, and then click “OK”.

Locate the “LowerFilters” value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
On the “Edit” menu, click “Delete”, and then click “OK”.
Quit Registry Editor and restart the computer.

Barring any fault with your driver hardware, this should work, so please report back.

Hi siryu

Ok, Well you can try "sfc /scannow" (without quotation marks) in an elevated command prompt, to see if there are any other corrupted files in windows, If it finds any, it will attempt repairs and try to fix them and if not, you may have to do a clean install of your OS.

Apart from that i'm fresh out of ideas.

tried " sfc/scannow "
result :
" Windows Resource Protection found corrupt files but was unable to fix some of them.
Details are included in the CBS.log windir\Logd\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log "

i tried to find the log file , to see what it said.
but i can't open it . " access is denied "

Hi siryu

If windows found corrupted files and can't fix them, you have choices.

1. Try and repair Windows. (Installation disk repair) or a complete re-installation of the OS.

2. You can attempt to read the log file yourself (difficult if you don't know what to look for). The guys at Windows Seven Forum can read it for you, and analyze).

Try here: http://www.sevenforums.com/performance-maintenance/184201-how-open-windows-cbs-log-files.html
Or here for how to read Log file: https://www.youtube.com/watch?v=9rqG59ph7y4

Access to the log file is thru an elevated command prompt.

I have found in the past that the quickest way is a complete re-installation. Its a pain I know, but an analyses of the CBS log file is time consuming and may not find the problem.

Make sure to backup any important personal files before re-installing Windows.

Hi siryu
