USB2-HUB-AG7 not wprking with DigitalPersona, U.are.U 4500 Fingerprint Reader

I replaced a D-Link DUB-H4 USB Hub with a USB2-HUB-AG7. When I plugged in a DigitalPersona, U.are.U 4500 Fingerprint Reader in to one of the 7 ports, it doesn’t work. Other devices (printer, mouse…) do work on it. Fingerprint reader was working with the D-Link DUB-H4 USB Hub and works when it’s plugged directly into the computer’s USB ports. In case it may help, I got the following information from the DigitalPersona website; Supply Voltage 5.0V ±5% supplied by USB - Supply Current—scanning < 100 mA (Typical) - Supply Current—idle mode 120 mA (Typical) - Supply Current—suspend mode < 0.5 mA (Maximum)
