The issue looks that. There's a limit (5 unit loads at 100mA) to the number/type of devices you can connect to a port. But if the card reader is self-powered (powered directly by the PSU), that should not be a problem.
The reader had a port to itself.I've sent the reader back.  I'm using an external card reader now.

Yes. And that port could not provide the reader enough power to operate properly as a high-power, high-speed USB device.
