-- Update June 2018 --

Silabs contacted us and says they have a new and improved version of the
functionality that this package provided.

(You're looking for the USBXpressHostSDK package)

We're not using these parts anymore, so have not verified this in anyway,

CP210xManufacturing Library for CP210x
--------------------------------------

Release packages contain binaries built using Ubuntu 11.10 Desktop 32-bit and
Ubuntu 12.04.1 Desktop 64-bit. These binaries may not be compatible with your
system, in which case it may be necessary to build the CP210xManufacturing
binaries using make.

                          (VID = 0x10c4)

Dependencies
------------

1. libusb-1.0

On Ubuntu:

  $ sudo apt-get install libusb-1.0-0-dev

2. g++

On Ubuntu:

  $ sudo apt-get install g++

Build CP210xManufacturing
-------------------------

Build an example console app, main, that uses the CP210xManufacturing source files to
communicate with a CP210x:

  $ make -f Makefile-main-linux

  Builds /Release/Linux/main

Build CP210xManufacturing.so.1.0, a shared object library that exports the
CP210xManufacturing library API

  $ make

  Builds /Release/Linux/libslabhidtouart.so.1.0

  See SharedObjectLibraryUsage.txt for more information on how to use a shared
  object library.

Configure Your System to Allow libusb to Access Your Device
-----------------------------------------------------------

CP210xManufacturing uses libusb-1.0 to communicate with the CP210x devices over
USB. In order for CP210xManufacturing to recognize your device, you must first
copy a udev file to /etc/udev/rules.d/. This udev file will automatically
enable read and write permissions for a device with the specified USB vendor
ID. Unplug and replug your device after copying a udev file for the permissions
to take effect. On some systems, it may be necessary to reboot the machine
before the new rules are applied.

CP2101 (VID: 0x10c4 PID: 0xea60):
- Copy SiliconLabs.rules to /etc/udev/rules.d/

Other:
- Modify an existing udev rules file for the required vendor ID

  SUBSYSTEM=="usb", ATTRS{idVendor}=="10c4", MODE="0666"
  SUBSYSTEM=="usb_device", ATTRS{idVendor}=="10c4", MODE="0666"
  
  - or - (optionally add a required product ID)

  SUBSYSTEM=="usb", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea80", MODE="0666"
  SUBSYSTEM=="usb_device", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea80", MODE="0666"
  
- SiliconLabs.rules does not specify the product ID and will therefore allow
  read/write access to all Silicon Labs USB devices with the Silicon Labs VID (0x10c4).
  The product ID is optional and will further restrict which devices the rules file
  will affect.
