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]
    # 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]

For more details on setting up USB devices, see the section called “USB Device Issues”.

Installation of libusb

Install libusb by running the following commands: 

./configure --prefix=/usr --disable-static &&
make

If Doxygen is installed and you wish to build the API documentation, issue the following commands: 

pushd doc                &&
  doxygen -u doxygen.cfg &&
  make docs              &&
popd

This package does not come with a test suite.

Now, as the root user: 

make install

If you built the API documentation, install it using the following commands as the root user: 

install -v -d -m755 /usr/share/doc/libusb-1.0.26/apidocs &&
install -v -m644    doc/api-1.0/* \
                    /usr/share/doc/libusb-1.0.26/apidocs
