USB drive now only works for certain devices

Brussels Sprout

As the title says, the USB drive on my mother's laptop now doesn't work for certain devices. Her external harddrive still works but her camera does not. If I connect either the camera or her portable SD-card reader device they don't come up in 'My computer' as drives like they used to in the past.

A possible cause of this issue is that 2 weeks I ago, in an effort to speed up her machine I ran in a registry script so as to regulate which Windows services are run automatically on her machine. I got the script from the following website: Black Viper link. Perhaps there is a windows service that has now been switched off which is responsible for detecting camera type devices? I've had a look through the services and all the plug and play ones appear to be starting automatically. Apart fromt hose i'm not sure what others would affect it.

What OS is she running?

I would assume its USB 2.0.

If its for certain devices you know the HW is probably ok, most likely a driver problem
