recommend usb hub for Beagle Board B7?

Hi all,
my usb hub seems not work for my newly purchased Beagle Board B7, I
need to connect USB devices from OTG port, anyone can recommend a
working usb hub which can bought from internet store?

Most likely your hub is ok, but you are not using an OTG cable.
I'd suggest to check your hub on another PC. If it works over there it
should work on beagle.
(and it should be a 2.0 hub, but if you recently purchased it, you
should be fine).
