How to setup CONFIG_USB_DEVICE_CLASS & CONFIG_WO_BUS_DIRS in the Kernel?


hello,
I could not change that parameter in kernel 3.8.11 because it seems not to be recognized in "make menuconfig". Do you know how to change it? Is it perhaps a bug?
If somebody know how to change this in menuconfig, I would be happy to know it.
I need a change of that parameter because..: http://www.libusb.org/ticket/119

Hi,

that's not a bug, the CONFIG_USB_DEVICE_CLASS option has been removed from the kernel after it had been deprecated for many years. (See https://lkml.org/lkml/2012/4/25/444.) What board are you working with? Isn't it possible to use a new and mainstream method of managing USB devices such as udev?

The board: I dont have the description; this is a specific embedded hardware for civil use and no public board name is defined (not mainstream available for few euros at standard shops on the street; the hardware cost is between 13000 and 25000 euros depending of the version).
udev: the responsible for the architecture said "NO WAY" because he seems to have issues with udev at another place (dont ask which one).

My target did not work. I had to deal with the non working libusb.
I wanted a working libusb because I wanted to use usb_modeswitch.
I just bought a huawei E220 which dont need usb_modeswitch and dont need a working libusb.
