[maemo-developers] Unable to get device detected with usb host mode on N800

[From: Vasudevan Srinivasan]

Hi,

The host side drivers were compiled in, CONFIG_USB_OTG_WHITELIST was set
off.
I could not get things up with the hub, so this time I cooked up a Y
connector
with external power source(a usb port from desktop without d+ and d-),
connected n800 and flash disk to other ends.

I was able to get the flash disk working only for a while, after a shutdown
and start of n800
it stopped working with the following errors in dmesg.
Have i messed up with something? Any clues / pointers?
