Try the OTG port.


Get the cables from special computing or gumstix or else where digikey??
https://specialcomp.com/beagleboard/xm.htm

The special comp usb hub with ethernet come in very handy
at times as well

USB Mini-A to USB A Female OTG Cable


We use

gumstix overo -> tobi -> mini usb otg cable -> normal usb cable-> 4 port 
dlink usb2 hub

Works nicely for usb wifi, usb bluetooth, usb soundcards , webcams , 
flash drives , usb jtag(for programming microcontrollers).
Also works well when powered from battery (mostly use sealed lead acid 
gel cells with low voltage cutoff)

trying to get a couple of oscilliscopes going at the moment (image and 
waveform capture)  via usb and
a logitech c910 webcam
