9. Run the XXUSBWin.exe program from the program directory or use one of the sample

programming packages to communicate with the CC-USB.

2.2 Installation for Linux Operating Systems

Linux provides a library libusb that allows to perform the bulk transfer to and from the CC-
USB and VM-USB USB port. The documentation and the library is available from
http://libusb.sourceforge.net. Fortunately, it is also included in modern Linux distributions, as
is the USB2 EHCI driver.

The prerequisites are:
(i) EHCI driver loaded - this is part of newer Linux distributions
(ii) libusb installed - installed automatically with newer Linux distributions.

IMPORTANT NOTE: At the time of this writing, root privileges are needed to use libusb,
when hot-plugging the device. This is needed for being able to write to the usb file system
usbfs. Please execute su before calling the demo program.
