Hello,

We tried to build our own daughter card for the Gumstix using both USB power and external power.
We use this pattern to choose which power source to use:

if externalPowerPresent:
    use ExternalPower
else:
    use USBpower

The gumstix works well with the USBpower except if we launch our application (which does heavy
computations).

The problems IMHO is that the gumstix is see by the computer as a 100mA usb gadget.

My questions are:
Is it possible to change it to 500mA?
If yes:
    how?
else:
    why?

Thanks,

Cyril
