Pair Logitech Unifying Receiver Devices In Linux With Solaar

<div style="text-align: justify;">The Logitech Unifying receiver supports connecting up to six compatible wireless mice and keyboards however, only the device that comes with the receiver is already paired (and thus, only that device will work out of the box with the receiver).</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Logitech provides a tool for pairing additional devices to the Unifying receiver but it's only <a href="http://www.logitech.com/en-us/support/unifying?section=downloads&crid=583">available</a> for Windows and Mac OSX so if you want to pair new devices or if you want to use a new receiver (in case you lose the old one for instance) and you're using Linux, you can use a third-party tool such as <i>Solaar</i>.</div><div style="text-align: justify;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh7bi5iaKjlWEkihT0wMX7mZsQrj8UnR4dWPuS83mBd0YhzzC7f2MW7jb_W8-tXItjZxfhns3P3ixF43jMOJKLhBridO35hs2CnTQCyRtctcVeK0SkPWMQScWZCJclkeKr6z6O6802St00/s1600/solaar-logitech_2.png" imageanchor="1" rel="image_group" style="margin-left: 1em; margin-right: 1em;"><img alt="Solaar Logitech" border="0" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh7bi5iaKjlWEkihT0wMX7mZsQrj8UnR4dWPuS83mBd0YhzzC7f2MW7jb_W8-tXItjZxfhns3P3ixF43jMOJKLhBridO35hs2CnTQCyRtctcVeK0SkPWMQScWZCJclkeKr6z6O6802St00/s320/solaar-logitech_2.png" title="Solaar Logitech" width="320" /></a></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><b><a href="http://pwr.github.io/Solaar/index.html">Solaar</a> is a Linux tool that allows you to manage <i>Logitech Unifying Receiver</i> mice and keyboards, that comes with both a GUI and command line interface.</b></div><br /><a name="more"></a><div style="text-align: justify;"><b>The application can be used to pair / unpair Logitech devices to the Unifying receiver,</b> it can <b>display the battery status for most devices</b> and, for some peripherals, it supports some extra settings that aren't available through the standard Linux system configuration:</div><ul style="text-align: justify;"><li><i>K750 Solar Keyboard</i>: display the current lighting value (Lux);</li><li><i>K360, MK700, K750 </i>and <i>K800 </i>keyboards: toggle the FN key state;</li><li><i>Performance MX Mouse</i>: change the DPI;</li><li><i>M705 Marathon Mouse</i> and <i>M510 Wireless Mouse</i>: toggle smooth scrolling.</li></ul><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhuPaFYBCBqTOjiQxNphoDZ7tIPnO2_uhW3Sn_BtSBumeMJQwSKy7313H-EqEf0TnwAL0NkWXKmKYrlZrYfJI0RH4JkyL3kb8SFBQYKEIQdCCqBzqZj42jmhAhMSto2yBGFzsr3arfIRy4/s1600/solaar-logitech.png" imageanchor="1" rel="image_group" style="margin-left: 1em; margin-right: 1em;"><img alt="Solaar Logitech" border="0" height="188" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhuPaFYBCBqTOjiQxNphoDZ7tIPnO2_uhW3Sn_BtSBumeMJQwSKy7313H-EqEf0TnwAL0NkWXKmKYrlZrYfJI0RH4JkyL3kb8SFBQYKEIQdCCqBzqZj42jmhAhMSto2yBGFzsr3arfIRy4/s320/solaar-logitech.png" title="Solaar Logitech" width="320" /></a></div><br /><div style="text-align: justify;"><b>Solaar</b> currently <b>supports all Logitech Unifying Receiver devices but only some newer Nano Receivers</b> are supported (USB ID: 046d:c52f, you can check that bu running "lsusb -d 046d:")</div><br /><br /><h2>Install Solaar in Ubuntu</h2><br /><div style="text-align: justify;"><b>Solaar can be install in Ubuntu through its official PPA.

<div style="text-align: justify;">A wireless hotspot enables a computer to serve as a router over Wi-Fi. Ubuntu lets you easily create a wireless hotspot by using the Network Manager, but it uses an ad hoc network and most Android and Windows Phone devices can't connect to such networks.</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiOZUfaA9qaOWDMUSUb5cPSOvkxY6tUrUxPOY5zFXe9DeN4P4HFPCBIboIr9kl7h2_9-JKDB5qXbFGhWUtuQKi4TiBFVwgvb3e2_1wIwvSDMoA03Db-XAHmJ2QympX5I9HFJDbWjF9ZqdU/s1600/hotspot_3.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="99" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiOZUfaA9qaOWDMUSUb5cPSOvkxY6tUrUxPOY5zFXe9DeN4P4HFPCBIboIr9kl7h2_9-JKDB5qXbFGhWUtuQKi4TiBFVwgvb3e2_1wIwvSDMoA03Db-XAHmJ2QympX5I9HFJDbWjF9ZqdU/s320/hotspot_3.png" width="320" /></a></div><br /><div style="text-align: justify;">For this reason, I've created (<b>in collaboration with <a href="https://plus.google.com/u/0/114564489020097923600/posts">Satya</a></b>) a script called <b>AP-Hotspot</b> that <b>automatically creates an infrastructure (Access Point mode) wireless hotspot in Ubuntu that should work with Android and Windows Phone devices</b>. The script uses <i>hostapd</i> and <i>dnsmasq</i> and it requires Access Point mode support for your wireless card - AP-Hotspot checks for this automatically and won't run if your wireless card doesn't support it.</div><br /><a name="more"></a><div style="text-align: justify;">So far, we've tested it in Ubuntu 13.04 with a Dell Inspiron 1545 (Wireless Card: Broadcom Corporation: BCM4312 802.11b/g LP-PHY) and a Dell XPS L702X (Wireless: Intel Centrino Wireless-N 1030) and the Android devices we've used have successfully connected to the Wi-Fi hotspot, unlike using the Ubuntu built-in hotspot feature. <b>Because this depends on the hardware you're using, it isn't something easy to test and it may not work for everybody but hopefully it will work for most configurations</b>.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">AP-Hotspot is based on <a href="http://forum.xda-developers.com/showthread.php?t=2009381">THESE</a> instructions (which by the way, you can use if you don't want to use our script), however, using the script should be a lot easier to set up an Access Point mode wireless hotspot because it automatically checks if all the requirements are met: the wireless card supports AP mode, if the WiFi is turned on but not connected to any network (without this, the hotspot doesn't work) and so on. Also, the script tries to configure everything automatically so in most cases, the configuration should take just a few seconds.<br /><br />Another script feature is that it displays notifications: when the hotspot becomes active and when a device connects or disconnects from the hotspot. </div><br /><br /><br /><h2>Install AP-Hotspot in Ubuntu</h2><br /><div style="text-align: justify;">AP-Hotspot is available in the main WebUpd8 PPA (note: there are some other packages in the main WebUpd8 PPA which you can see <a href="https://launchpad.net/~nilarimogard/+archive/webupd8/+packages">HERE</a>) for Ubuntu 13.10, 13.04, 12.10 and 12.04, however, because this can't be tested in VirtualBox, it has only been tested on Ubuntu 13.04 and 13.10. The script requires Hostapd 1.0 which is available by default in Ubuntu 12.10, 13.04 and 13.10 - for Ubuntu 12.04, you can use a <a href="https://launchpad.net/~network-manager/+archive/ppa">PPA</a> to install Hostapd 1.0.<br /><br />That said, let's proceed with installing AP-Hotspot:</div><pre class="linux-code"><code>sudo add-apt-repository ppa:nilarimogard/webupd8<br />sudo apt-get update<br />sudo apt-get install ap-hotspot</code></pre><br /><div style="text-align: justify;">If you're not using Ubuntu or don't want to add the main WebUpd8 PPA, you can get the script from <a href="https://launchpad.net/~nilarimogard/+archive/webupd8/+packages?field.name_filter=ap-hotspot&field.status_filter=published&field.series_filter=">HERE</a> (but it has only been tested in Ubuntu). If you're not using the deb, make sure you also install the following packages, required by the script: <i>hostapd</i>, <i>dnsmasq</i> and <i>iw</i>.</div><br /><br /><br /><h2>Usage</h2><br />To start AP-Hotspot, use the following command:<br /><pre class="linux-code"><code>sudo ap-hotspot start</code></pre><br /><div style="text-align: justify;">The first time you run the script, it tries to automatically detect which network interface is connected to the Internet, the  wireless network interface and so on, however, if the detection  doesn't work correctly, you can enter these manually:</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjuFl64qbTXy9OsJ17V03ZLeX19gFD3P5XyxwkaUDr3wKyPHDEKQbc9ihEv6BvAHKiVQ0kRAtybaM7PrAPAh03fBrLyNicEMdIsY5lpZ1-7DqgxkuxAP0k18BumwZyQCtvTfanSD3zkz04/s1600/hotspot_1.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="88" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjuFl64qbTXy9OsJ17V03ZLeX19gFD3P5XyxwkaUDr3wKyPHDEKQbc9ihEv6BvAHKiVQ0kRAtybaM7PrAPAh03fBrLyNicEMdIsY5lpZ1-7DqgxkuxAP0k18BumwZyQCtvTfanSD3zkz04/s320/hotspot_1.png" width="320" /></a></div><br />Then, you'll have to enter the desired hotspot Access Point name and password:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEga2TU6SCSNn-eI8DUSngYkjq6Sl2wvnKA27TuBn4w7l4_uyljpYTfmz1Vzxfup4JJLYo2mlpK0nOzrRXN3McPA2xLECzqc2q7uMPwTCC1Y3cyH2CNXeLj6BdeSpm760VUVHDqJWYkbKHY/s1600/hotspot_2.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="123" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEga2TU6SCSNn-eI8DUSngYkjq6Sl2wvnKA27TuBn4w7l4_uyljpYTfmz1Vzxfup4JJLYo2mlpK0nOzrRXN3McPA2xLECzqc2q7uMPwTCC1Y3cyH2CNXeLj6BdeSpm760VUVHDqJWYkbKHY/s320/hotspot_2.png" width="320" /></a></div><br />If later on you want to run the configuration again, use the following command:<br /><pre class="linux-code"><code>sudo ap-hotspot configure</code></pre><br />To stop the wireless hotspot, use:<br /><pre class="linux-code"><code>sudo ap-hotspot stop</code></pre><br />Or, if you want to restart it, use:<br /><pre class="linux-code"><code>sudo ap-hotspot restart</code></pre><br />To see all the supported commands, simply type the following in a terminal:<br /><pre class="linux-code"><code>ap-hotspot</code></pre>
