Hi I been reading over and over looking on how to solve his but i
havent found the answer.
SO basically i have the same problem a lot of people had trying to
configure the USB OTG port of the beagle as Host.
I already have shorttened pin 4 and 5 so you can rule that out.
i already tried the
1.- modprobe g_zero
2.-echo host > /sys/devices/platform/musb_hdrc/mode
whitout any succes. i always get a FATAL: error inserting g_zero <path
2.6.32> Device or resource busy...
Yes im using a power supply to power up the beagle.
and yes im using a hub with power supply so it doesnt takes power from
the beagle.
I check pin 1 and for some reason its always 0 (Showing that
definitively the beagle is not changing from OTG to host).
Im using the latest Angstrom from http://www.angstrom-distribution.org/demo/beagleboard/
which is also a problem because i dont know which file to get (Im
talking about version) my beagle is up and running i can vnc through
OTG and has internet access. However the next step in my project was
to add some peripherals.
Im pretty sure that the problem is related to the version of Angstrom
or Uimage or boot or ine of those files there. However without knowing
which one should I pick i wouldnt change it jut like that. SO PLEASE
is someone has a REV B6 and it made his OTG work as HOST tell me the
SECRET!!!!
I plug in the proper otg cable and it just works when using angstrom on my b6 boards
Hi! I have the exact same problem om my revC4 BB.
Ångström worked fine, but with Debian and Ubuntu i only get the
"install" screen on my monitor that tells me to select install
language..
- Of course without any keyboard detected I am stuck.
Help is greatly appreciated.

Are you sure? the original poster is using the otg port in host mode,
you might be using the ehci..

lets start with the hardware, which usb port, are you using a usb 2.0
hub? keyboard connected to said usb 2.0 hub?
beyond that, can we get a serial boot dump?

Hello,
I had the same thing with the demo image of Ubuntu from the
beagelboard webpage. I solved it by using rootstock to create a
minimal image which did not ask for the language - everything came up
fine and I could then go ahead and install the windowing toolkit I
needed with apt. I did not use the OTG though but the other USB port
but I had teh same problem of the keyboard not coming up in the Ubuntu
demo image - yes it was running through a USB 2.0 hub :).
Cheers,
Neil
Thanks for your answers!
Due to the fact that the OTG port worked fine under Ångström, i continued using this port for my emDebian install.
When i measured pin 1 on the OTG, it was always grounded, thus not operating in “host-mode”, even though pin 4 and 5 were connected.
The solution proved to be very simple. - Use the powered USB 2.0 hub in the USB A host port.

"�ngstr�m worked fine", sounds good to me, no?
from? http://www.angstrom-distribution.org/demo/beagleboard/
use 2.6.32
Everything else is ancient...
(and the multiple file names is just a thing Angstrom/Bitbake does..)
Regards,
Modprobe g_zero doesn’t make sense here, as that is not a host driver. Don’t do that. Plug in a keyboard instead. Please provide the full kernel log.
