What is the effect of plugging a USB 3.0 device into a Plugable 7 port USB 2.0 hub?
Specifically I am plugging 2 USB hard drives into the hub and also using it to power a Raspberry Pi. The USB drives are:
Buffalo HD PX320U2 (USB 2.0)
WD My passport Ultra 1TB (USB 3.0)
I have read that the USB 2.0 spec only allows the device 500 mA/port and that USB 3.0 devices can need 900 mA
I have also read that the Plugable 7 port USB 2.0 hub is fully forward and backward compatible with USB 1 and USB 3
Can you help?
