I have 7 units running on a 3.0 hub right now. With default voltage and at 120mhz they get very hot. You can barely touch the heatsink.
Is this ok or should they be extra cooled with a fan?
Another thing is rhat I cannot get various hub running on a raspberry pi. All those hubs fail in combination with the moonlanders. Right now I am running from my normal pc, but I dont want my pc running 24h.
There's an oddity with the pi and some usb3 hubs in that they won't see some devices, notably usb 1.1 devices. The 'trick' is to plug the usb3 hub into a usb2 hub which is then plugged into the Pi.
Have just tried it on a Pi 2 and it seems to have worked. (running ubuntu)
lsusb on the pi shows :-[email protected]

Don't know if it will fix you're problem but worth a try.
