I have a digital camera via usb and when i switch it on i used to beep and be there in my computer as a removable drive!,now it says the following everytime i switch it on:
an error occurred during the installation of this device
one of the filter drivers installed for this device is invalid.

Also when i try to add a slave drive it says the same,does anyone know how to solve this??thanks

Have you tried reinstalling the USB drivers that came with the camera?

It will not take the drivers,also it wont read the slave drive,it comes up with the same errors!!
