For libusb to function, the following options have to be enabled:

CONFIG_USB_SUPPORT, CONFIG_USB, minimum one host controller driver
(CONFIG_EHCI_HCD, CONFIG_UHCI_HCD or CONFIG_OHCI_HCD) and finally
CONFIG_USB_DEVICEFS which perhaps is not a requirement, but it is
recommended for now.

udev can play some tricks, but if your kernel does have the basic USB
support, libusb should be useful.

You can try the command:

dmesg | grep -i usb

After booting your system in order to find out if the kernel has some
USB support enabled.


I hope this is helpful to you! :)
