Windows 7: usbscan.sys and dot4usb.sys missing

usbscan.sys and dot4usb.sys missing

hi,

for months i am trying to install my HP C3180 MFP printer on Win 7 Pro 64-Bit (german) without success.
The HP AIO driver installation program always failed with a fatal error - thats already posted on their forums without reply.

The device driver installation when plugging the printer fails. The corresponding info in the setupapi.dev.log shows following error
inf: Opened INF: 'c:\windows\temp\dmiwu\{8e133662-0961-4108-b196-a1e3622d3f42}\hposcu01.inf' ([strings.0007])
inf: Opened INF: 'C:\Windows\inf\sti.inf' ([strings])
!!! sto: Driver package references a missing external file 'C:\Windows\system32\drivers\usbscan.sys'. Error = 0x00000002
!!! sto: Failed to retrieve driver package copy files. Error = 0x00000002
!!! sto: Failed to get list of driver package files. Error = 0x00000002, Filename = c:\windows\temp\dmiwu\{8e133662-0961-4108-b196-a1e3622d3f42}\hposcu01.inf
on the web i found some info about that usbscan.sys file but all related to WinXP and Vista. my old, still existing, WinXP installation contains this file, but its definitely not compatible - didnt even try, and dont want.

i wonder how to safely restore that in case it should be there.

when running the always failing HP installation the setupapi.dev.log shows

inf: Opened INF: 'D:\Users\Lou\Downloads\Drucker\AIO_CDA_NonNet_Full_Win_WW_130_140\hprdv_vp.inf' ([strings])
inf: Opened INF: 'C:\Windows\inf\DOT4.INF' ([strings])
!!! sto: Driver package references a missing external file 'C:\Windows\System32\drivers\Dot4usb.sys'. Error = 0x00000002
!!! sto: Failed to retrieve driver package copy files. Error = 0x00000002
in this case its the dot4usb.sys file failing. similar problem, is that a system file and if, how to restore.

i am not sure if this is the reason for the failing installation but it looks so.

help is really appreciated

thanx
Lou

First you should run a SFC /SCANNOW as the usbscan.sys is part of windows 7 driver:

SFC /SCANNOW Command - System File Checker

or

SFC /SCANNOW : Run in Command Prompt at Boot

This should repair that file.

Go through this thread carefully, hopefully you'll find a solution.

using the SFC did not recognize any problems. nothing missing, no integrity problems and it did not recover any of the missing files.

found the usbscan.sys in C:\Windows\System32\DriverStore\FileRepository\sti.inf_amd64_neutral_9d9a7113099a28a2 and copied it to System32 but the next driver install failed with serscan.sys missing. thats also there, copied to System32, reinstall, failed again.

this time a bunch of other files like hpxxx.inf files missing.

probably a bad/corrupt/incomplete Windows 7 install. but cant remember anything suspucious during the installation.

decided to re-setup Windows 7 on the existing installation, checked the previously reported files and all there.

plugged in the printer to the USB port and now all worked.

it seems somehow the Windows 7 install was messed up. from experience with Windows 7 installs, messing that up is a feat.

however, finally made it work.
