Introduction to libusb

The libusb package contains a library used by some applications for USB device access.



Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

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]

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 &&

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

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

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-1.0.27/apidocs &&
install -v -m644    doc/api-1.0/* \


Installed Programs: None
Installed Library:
Installed Directories: /usr/include/libusb-1.0 and /usr/share/doc/libusb-1.0.27
