Greetings,

Welcome to the forum.

I am not a HP employee.

 

The main thing I can think of would be not enough power from the USB splitter to more than two external USB devices.

 

You could have a faulty card reader.

 

Try the card reader by itself. 

 

I have a USB 2.0 hub in my PC. The hub requires a Molex power connection to power additional USB connections.

 

You can only run so many USB ports on one MB USB header.

 

Regards
