Approximate build time: less than 0.1 SBU
Required disk space: 6.2 MB

9.16.2. Configuring Libusb

To access raw USB devices (those not treated as a disk by the mass-storage driver), appropriate support must be available in the kernel. Check your kernel configuration: 

Device Drivers --->
  [*] USB support --->                                             [USB_SUPPORT]
    <*/M>   Support for Host-side USB                                      [USB]
    [*]     PCI based USB host interface                               [USB_PCI]
    # These are most common USB controller drivers for PC-like systems.
    # For modern systems often [USB_XHCI_HCD] is the only one needed
    # even if the system has USB 2.0 ports:
    < /*/M> xHCI HCD (USB 3.0) support                            [USB_XHCI_HCD]
    < /*/M> EHCI HCD (USB 2.0) support                            [USB_EHCI_HCD]
    < /*/M> OHCI HCD (USB 1.1) support                            [USB_OHCI_HCD]
