USB 3.0 port works unless a hub is plugged into it.

I have a laptop USB 3.0 port that works with a USB <> SATA enclosure, but if I plug a USB 3.0 hub into the port and plug the USB <> SATA enclosure into the hub, I get nothing.

I tried two USB 3.0 hubs from different manufacturers; both with the same result. I can't figure it out. Both hubs are externally powered. The lappy is an Asus K53SD.

Any ideas?

Do other devices work in the USB hub? Does the hub show up in lsusb?

Good idea to test any device on hub, look for any /var or dmesg or lsusb.

A port has a few items. One is power, one is usb spec and other is device chip. I guess it's possible that for some reason the usb power is shutting down. Possible that it falls back to an unsupported speed/chipset.

An oddity of the port? Crack, loose,...

Distro may not support the hub fully.

The sata to usb may have an oddity about it or the hubs can't really power it fully or at the correct time.

Try running the hub without the external power supply.

My personal experience has been that powered hubs work better with Windows, and unpowered hub work better with Linux.
