I just found your address as a better one than linux-kernel:
*******
My typing follows a line with a bunch of stars. That is followed by
command output.

I have a USB 3.0 hub and switch that I need to use to switch devices
between a Linux desktop, laptop and MacBook Pro. At first, I was
testing with just a keyboard and mouse.
The switch is connected to USB Bus 1.
With keyboard and mouse plugged in, OS/X is all happy and sees them fine.
They do not show up with "lsusb -t"
# lsusb -t
[...]

|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M

As you see, with plain "lsusb",
the story is different, but the same story were my MS Natural
keyboard plugged in instead of the Apple. Next, I plugged in
an SD card reader and, to my great surprise, it worked:
# lsusb -t
[...]
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 1: Dev 25, If 0, Class=Mass Storage, Driver=usb-storage, 480M
|__ Port 1: Dev 25, If 1, Class=Chip/SmartCard, Driver=, 480M
|__ Port 4: Dev 5, If 0, Class=Hub, Driver=hub/4p, 480M
*******
so I was able to mount the device.
So therefore, Linux can work with USB devices hung off of a hub hanging off
of a switch, but not keyboards and mice. And these are keyboards and mice
that work just fine when plugged directly into a motherboard USB port.
Why would that be?
Since I have tried several variations of hubs and switches, it gets down
to Linux needing some fixes. Have they already been made? If so,
where can I get the patch? If not, please point me at some code so
I might be able to fix it -- at least for myself.
Thank you. Regards, Bruce
