Voltage too low for a powered USB hub

Voltage too low for a powered USB hub

D-Link DUB-H7 (USB2.0) USB HUB 7P 7xUSB-A / B 1xUSB-B / B + cable + Power Supply (Personal Computers)

Customer Review

The USB hub is mainly bought by a Raspberry Pi to operate. Unfortunately, has quickly proven that the voltage supplied by this HUB is too low. Too bad. That I have under an "active" - ​​not presented USB hub - thus equipped with its own power supply.
