[Gumstix-users] custom overo board and usb

[Florian W. <flo...@if...>]

Hi all,
 
I´m planning a custom baseboard for the overo and at the moment I'm looking
at the summit schematics to get a clue about the usb wiring and I´m asking
myself if the TPS61202 is only used to boost the input voltage. Since I´m
using a 5V regulated DC-DC converter I thouhgt about not using the TPS61202
on my own board. The only thing that I don´t understand is the USBH_CPEN on
the EN Pin of the TPS61202 . Is it also possible to supply USB_VBUS with 5V
constantly (at least I don´t know what USBH_CPEN does)?
 
I´m also asking myself wether to use the OTG or Host port (I´d like to use
an USB cam in the future). Could the Host port supply devices with 500mA? 
 
Regards,
Florian
