How to know whether CONFIG_USB_DEVICEFS is enabled or not in the kernel?

Asked by Uqbar on 2010-12-07

In order to have a USB scanner working I need to have CONFIG_USB_DEVICEFS enabled in the kernel.
Which seems to be a good thing anyway.

you can check the configuration file for your kernel in /boot, /boot/config-2.6.35-22-generic is an example.
Afaik CONFIG_USB_DEVICEFS has been disabled since karmic since it's incompatible with udev, I don't know much about this though.
