Description: Ubuntu 15.10
Release: 15.10
linux-image-4.2.0-17-generic
When I plug USB 3.0 storage device(Transcend TS32GJF780 USB 3.0 32 Gb
flash drive) into one of USB 3.0 ports in USB hub (DELL U2713HM monitor)
and hub is connected to USB 3.0 port on my MB - no USB device is
detected. lsusb shows no device is connected to hub ports:
lsusb -t
/: Bus 06.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M

/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M
Expected: hub device on Bus 04/Port1 has storage device listed.
Workaround: if I check if power is supplied to the USB 3.0 hub device, I
see:
cat /sys/bus/usb/devices/usb4/4-1/power/control
auto
Then if I manually turn power on:
echo on >/sys/bus/usb/devices/usb4/4-1/power/control
USB 3.0 device appears and works.
This problem is not reproducible if the same USB hub is attached to USB 2.0
port, so it is likely to be USB XHCI driver problem.
