Free USB on baseboard?

[kruszi]

Hi, I am doing a custom baseboard.
For this I'd like to use USB Host for external USB Stick.
USB OTG (Mini USB) is for having my device connected to a PC.
Now I am looking for a way to connect a 3rd device (keyboard) to the wandboard.
Does anyone see another chance than using a USB hub?
StbB1_SSRXP, StbB1_SSRXN, StbB1_SSTXP and StbB1_SSTXN are not connected according to the schematic.
I guess these belong to the USB OTG and are not usable for my purpose (keyboard) - am I right ?

Thanks for helping me out - I'm missing some knowledge on USB ...
