Re: [Gumstix-users] USB Host problems

you're using miniports.  I used the OTG port and I think it will only push 100mA.  I actually bought the Tobi for the one A port.  I wanted a full size port for our radios. 

I think I'll be OK.  I need to have an android device on one side and a jtrs radio on the other.
