It overcomes one limitation of the IO Dock: You can&#8217;t simply hook it to a USB hub.

(I used a powered hub <a href=\"http:\/\/www.amazon.com\/Belkin-4-Port-Hi-Speed-Mobile-F5U404-BLK\/dp\/B000SAB34O\" target=\"_blank\">Belkin F5U404<\/a>.) This has certain limitations, though. Why? USB knows two basic types of port power &#8211; normal USB ports are supposed to deliver a 5V supply current of up to 100mA. That is enough to power simple interfaces and USB sticks. It is not enough to charge your phone, or to power a USB master keyboard.\u00a0 So using a hub without power supply would normally mean that the iPad is not properly charged &#8211; but the way the iPad charges is actually hard-wired <a href=\"http:\/\/pinouts.ru\/PortableDevices\/ipod_pinout.shtml\" target=\"_blank\">in the IO Dock&#8217;s iPad connector,<\/a> so <strong>the iPad will charge even without a powered hub.<\/strong> (It is connected to the USB port&#8217;s input rather than to its output anyway).\u00a0 IMPORTANT: As we will be using the IO Dock&#8217;s power supply, there are some limits to what we can drive with our hub. Please: <a href=\"http:\/\/www.untergeek.de\/2013\/01\/tech-hack-alesis-io-dock-with-usb-hub#power\">See the FAQ<\/a>. And I&#8217;ll have a more thorough look at the IO Dock&#8217;s power supply circuitry soon.<\/li>\n<li><strong>The hub&#8217;s connector cable<\/strong>. These cables have a flat A-type USB plug to go into your computer, and usually a micro-USB B-type plug like the ones for charging your phone (if you don&#8217;t have an iPhone, that is). We are going to cut up this cable and configure it to supply and interface the hub within the IO dock.<\/li>\n<li><strong>2x <del>1.27mm<\/del>\u00a02mm grid pinstripe connectors &#8211; one 6-pin male, one 6-pin female<\/strong>.

A <a href=\"http:\/\/www.esi-audio.de\/produkte\/midimate2\/\">USB-to-Midi interface<\/a>, for example, or an audio interface, a USB keyboard, or a <a href=\"http:\/\/www.keithmcmillen.com\/12step\/overview\" target=\"_blank\">foot controller<\/a>. It might not work with the fancy flux compensator control you just bought on eBay, along with a floppy disc holding the drivers. Take a look <a href=\"http:\/\/iosmidi.com\/devices\/\" target=\"_blank\"><del datetime=\"2013-10-07T19:13:50+00:00\">at this device list over at iosmidi.com<\/del><\/a> (no longer online, archive copy <a href=\"http:\/\/web.archive.org\/web\/20130121040234\/http:\/\/iosmidi.com\/devices\/\" target=\"_blank\">here<\/a>.)<\/p>\n<p>Another consideration is<strong> how much power the device needs.<\/strong> We&#8217;ll get to that in a minute, for the moment just remember that you probably shouldn&#8217;t defile the IO Dock by hooking up a mug warmer or a fan to it.<\/p>\n<p><a name=\"pingrid\"><\/a><\/p>\n<h3>What type of connector did you use? Where can I get it? And why do you list only sockets, no plugs?<\/h3>\n<p>Another excellent question. As noted before, I had 2mm SIL pinstripe sockets lying around in one of my parts boxes, so I did not think much of it. From the feedback I realised that they are not that easy to come by. Normal IC sockets are in the 2.54mm grid, so 2mm grid SIL sockets are hard to get a hold on. <a href=\"http:\/\/uk.rs-online.com\/web\/p\/sil-sockets\/7020663\/\" target=\"_blank\">I&#8217;ve found them in RS Components&#8216; Online Catalog<\/a>; unfortunately RS is not too keen on selling to private persons, but at least that means that the part is out there, somewhere. (There&#8217;s presumably <a href=\"http:\/\/cgi.ebay.com\/ws\/eBayISAPI.dll?ViewItem&amp;item=121158885416&amp;ssPageName=ADME:L:OC:US:3160\">another source on eBay<\/a>, thanks Shep<a href=\"http:\/\/www.untergeek.de\/2013\/01\/tech-hack-alesis-io-dock-with-usb-hub\/comment-page-1\/#comment-13005\"> for commenting on this<\/a>.)<\/p>\n<p>And why didn&#8217;t I tell you to order socket plugs as well? Same reason, really &#8211; as a hacker, you use what you have. And turned sockets are excellent as plugs; just solder the cable to the socket side rather to the pin.<\/p>\n<p><a name=\"power\"><\/a><\/p>\n<h3>Is the IO Dock really capable of powering three additional USB loads?<\/h3>\n<p>Good question, actually. No, really. You may know that an iPad charging can draw a pretty hefty current &#8211; 2.1A, as far as I know. The IO Dock&#8217;s power supply is capable of delivering up to 3.0A, so wiring three 500mA loads to it &#8211; a USB\/Midi keyboard, a Maschine-type controller, and a light &#8211; will drive it over the edge. Well, sod and burn the power supply, but the IO Dock&#8217;s internal supply voltage comes from a regulator, \u00a0and you wouldn&#8217;t want to burn that.<\/p>\n<p>In my first experiments I hooked up a device that, while switching on, seemed to produce a spike current that demanded just a little bit more than the hub could supply &#8211; and this caused the hub (and the dock) to lose its power. I drew three observations from that: (1) Better add a buffer capacitor for the hub. (2) If you switch on the IO Dock with the load already connected, it works. (3) The IO Dock&#8217;s internal regulator is possible short-circuit proof, but no guarantee for that. It may still burn.<\/p>\n<p>Scared now? You should be.<strong> I&#8217;m pretty confident that you are OK with one 500mA load (i.e. one device that only works on a powered hub, not on the camera connection kit itself) and two small loads like MIDI interfaces, but don&#8217;t blame me if anything goes wrong. We&#8217;re absolutely doing this on our own risk &#8211; I do, you do. Consenting adults, you know.\u00a0<\/strong><\/p>\n<h3>Does the USB port for connecting the iPad to a computer still work?<\/h3>\n<p>Oddly enough, no. Which makes it all the more surprising for me that the hack actually works &#8211; a normal IO Dock seems to drive the iPad as slave rather than as a master, so once you force the iPad to be master, it won&#8217;t sync. (Theory.)<\/p>\n<p>What the IO Dock still does when you plug it into a computer: It registers as an audio interface. Here what a Linux machine tells me:<\/p>\n<pre>[14339.660194] usb 5-1: new full-speed USB device number 2 using uhci_hcd\r\n[14339.818328] usb 5-1: New USB device found, idVendor=13b2, idProduct=0020\r\n[14339.818343] usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0\r\n[14339.818353] usb 5-1: Product: Alesis iO Dock\r\n[14339.818363] usb 5-1: Manufacturer: Alesis\r\n[14339.866455] usbcore: registered new interface driver snd-usb-audio<\/pre>\n<h3>Does the IO Dock&#8217;s MIDI and Audio interface still work?<\/h3>\n<p>Hell, yeah! That&#8217;s what it&#8217;s all about, isn&#8217;t it?<\/p>\n<h3>What if I don&#8217;t want the hack any more? Is it reversible?<\/h3>\n<p>Yes. Just unplug the hub, replug the IO Dock&#8217;s USB connector plug, and everything is the way it used to be. That&#8217;s why we did it with connectors rather than with the usual brute-force cut-the-wire-solder-it-in-to-hell-with-tomorrow approach.<\/p>\n<p>You can even try it out before cutting a hole into the IO Dock&#8217;s housing.
