I have bought a 20 port usb hub just to find out that is not working in Linux :(
for example if I insert one hard disk is working fine but if I insert a second hard disk, the second hard disk is not working at all , it ejects and inject the hard disk automatically.
The same happens with the USB sticks.
If I insert a hard disk straight to my PC usb 3 is working fine but with the 20 port hub I am having problems.
However I have tested the same hub under an old pc with a usb 2 and everything was working fine , I could even put 5-6 hard disks in the hub and all were working fine.
So whats wrong with Linux and USB3?
