Hi Paul,

Did you use the mini-A to mini-B cable connected to the hub?

If you could attach your overo_android_defconfig I could check if anything is wrong. You should also try and disable the USB port from being suspended by issuing:

echo -1 > /sys/module/usbcore/parameters/autosuspend

Hi Kevin,

Hi, I've also had a lot of problems with gumstix boards and USB
functionality. There is a cable called a mini A to mini B cable that
you need to enable host mode on either the host port or the OTG port.
The mini A end goes into the port on the board and the mini B end
goes into a powered USB hub.

Make sure that host mode is enabled in the configuration script.
Thank you for your reply!  I have the OTG port working using the 
2.6.34/36 kernels, I just don't know what options I need to set in the 
defconfig for the .38 kernels, copying the USB options from the .36 
recipe does not seem to work, and the .38 recipes for the Beagleboard 
etc seem to have it configured in gadget mode.

This is all I get in dmesg when plugging/unplugging the powered 
hub+ethernet adapter:
