[OLPC-devel] some usb status

[Ronald G Minnich]

with my 2.6.14 tiny kernel, which is the only one that seems to fit 
inflash with usb in, I see this:

I have a usb mass store plugged into the usb near the audio jacks. I am 
wondering what else I need to config to make this go. My config looks 
like this:

#
# USB support
#
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB=y
# CONFIG_USB_DEBUG is not set

Anything else I should turn on? I have put this in the 
drivers/block/Makefile:
CONFIG_BLK_DEV_UB=y

since there is no way to do it via any config tool -- is this the right 
thing to do?

What would it take to make a usb store come up when the kernel comes up? 
I'd really like to make usb work from linuxbios-started kernels.

thanks
