Hello,
Hello Robert,

does it mean that that only the OTG port can be used?
Both the OTG/EHCI can be used, the patches are located in the Angstrom
git tree and i have them in my consolidated diff.
I tried to connect the upstream part of an USB 2.0 hub to the
beagleboard with the help of an USB mini A/B -> USB A
adapter cable.
That should have powered it.. was this the OTG port? The ehci isn't
designed to provide power to the board...
Unfortunately, the beagle gets no power with this setup.
Do the upstream parts of a USB 2.0 hub (the part you
usually connect with the PC) supply power (the hub is
selfpowered with an external power adapter) or
only the "client" ports where you plugin your
peripherals? I have tried with another 2.0 hub
with the same result.
I googled a lot about this topic but it didn't
bocome clear to me.
Without a 5vdc power supply connected to the dc jack, you'd use the
OTG port for power and the ehci for USB connectivity.
