Computer fails USB system requirement for C4780 printer

[Shoobydoo]

When downloading HP printer driver onto brand new computer I get the following system requirements error:

"This computer does not have the necessary USB software support to allow completion of a USB intallation."

The printer is not connected.

All the USB ports on the computer work fine in that they recognise and allow me to read a flash drive. The computer manufacturer says it is not their problem as the USB ports work fine.

What could be the problem?

Many thanks.

Hi,
Click the Start button and type %temp% into the search bar, then open the shown Temp folder.

Open the latest HP installation folder which begins with 7z (e.g. 7zs1234)
Open the Setup folder.
Locate the usbready.exe file and rename it into usbready.old.exe
Browse back to the main extraction folder (the folders who starts with 7z) and launch the Setup.exe file.

Now follow the installation and check for any difference.

Regards,
Shlomi
