No usb devices reconised and Launch.exe?

[bondbill2k2]

I have with me a lapotp used by our admin team, we don't allow it on the network as its used outside of school too. Well it was brought to me yesterday with an issue, any USB device they tryed in it didn't work, I too have tryed several devices and none have been reconised including 3 different flash drives.

 

The USB drivers appear fine and have worked up until recently. The device is enabled and "working correctly" according to device manager.

 

ALso on boot a warning is displayed "launch.exe stopped working" altho having a google around for what this launch.exe exactly is has proved unsuccesful.

Did you try uninstalling the drivers and reinstalling them?

 

 

Yeah, launch.exe is one of the multi-purpose files. So much uses it that you can't really get specifics for it.

I can't say I've ever heard of launch.exe - I'd suggest running regedit or msconfig and having a look for launch.exe (find in regedit) to see if there's any sign of what's loading it. You're probably going to struggle to uninstall the drivers (I think they may be inbuilt into windows) however, you could try uninstalling the device, rebooting and allowing windows to refind it (or force device manager to scan for new hardware).

 

I wonder whether launch.exe is actually malware, may be worth running malware scans on the laptop (being a device used externally and essentially being unmanaged). Malware could also be a reason for drives not showing up. Have you checked device manager and computer management->disk management to see if the usb devices are being detected at that level?

 

Cheers

Ran some scans with malware stuff and cccleaner, didnt find any malware and yes I did reinstall the USB drivers. It seems to be working after a cleanrup and the USB port the staff had originaly complained about was pysically broken inside -_- tested the two back ones and worked fine and removed files that seemed to be related to launch.exe manually.

We get this quite regularly..

If they are using a none-administrator login, try it as administrator. If not, ensure that there is a drive letter assigned to that USB drive in disk management.

 

disregard: just noticed you said they work at the back
