Presumably it notices keyboards and mice; hopefully it's not limited to those. &lt;/&gt;</p> <p>I posted a question at the Arduino Forum:<br /> <a href="http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1290629040/15#15" rel="nofollow">http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1290629040/15#15</a><br /> and I am now on the trail. It appears that the underlying Sun Ray 2 supports a bunch of USB devices, so one path is to 'make them available'. The link posted by kg4wsv has some instructions on hw to do that.</p> <p>I will also need to bottom it out for the RDC protocol.</p> <p>Summary: not there yet, but it looks like it may be fixable for Sun Ray 2.<br /> Don't know yet about Windows Thin Client in general. I think it depends on what the Remote Desktop Client protocol (RDC) supports. </p> <p>(Aside: It is almost like google can't see any of these documents, because non of my queries have found much/anything of use). </p> http://forums.leaflabs.com/topic.php?id=537#post-2865 Mon, 29 Nov 2010 19:21:22 +0000 mbolivar 2865@http://forums.leaflabs.com/ <p>Ugh. That's disappointing news; sorry you didn't get the Arduinos working.</p> <p>We're still debugging our own serial bootloader; hopefully we'll all have better luck with it than has been has do far with Arduino. By the way, the 0.0.9 docs preview includes the serial protocol used and a section on flashing a bootloader:</p> <p><a href="http://static.leaflabs.com/pub/leaflabs/maple-docs/docs-0.0.9-preview/bootloader.html" rel="nofollow">http://static.leaflabs.com/pub/leaflabs/maple-docs/docs-0.0.9-preview/bootloader.html</a></p> <p>gbulmer, I believe you had requested the "HOWTO" in particular.

They are a bit like graphical dumb terminals, similar to running X Windows on the thin client machine, with the applications on the server.</p> <p>There is no image of 'proper' MS Windows, or the MS Windows applications running on the thin client computer. <em>Almost</em> everything except drawing pixels is running on the remote, shared server.</p> <p>MS Windows Thin Client is popular in schools and colleges because it is much easier to manage servers than networks of PC's running local copies of MS Windows. Thin clients are quite hard to hack because they don't run programs.</p> <p>The major problem is getting the server to recognise that a thin client has something plugged into USB. Typically the server only recognises a few different types of USB device plugged into the thin client. A local school wanted to do robotic workshops (which I run), but we could not get an Aduino or Maple recognised as a USB device.</p> <p>The Arduino UNO does NOT need a 'proper' driver installed (unlike its FTDI-based predecessor). So I had hoped it might be feasible to get the UNO recognised by an MS Windows Thin Client network. But it didn't even notice a USB device.</p> <p>I am posting to alert LeafLabs to the problem, and to ask people who understand MS Windows Thin Client if they have any suggestions for how to make progress. </p> http://forums.leaflabs.com/topic.php?id=537#post-2832 Thu, 25 Nov 2010 22:07:20 +0000 crenn 2832@http://forums.leaflabs.com/ <p>I'm always using Windows 7 Pro, never encountered Thin Client however I presume it's an image loaded on at start up.</p> <p>I've had the occassional problem with Windows, but nothing that can't be overcome. </p> http://forums.leaflabs.com/topic.php?id=537#post-2830 Thu, 25 Nov 2010 20:23:39 +0000 gbulmer 2830@http://forums.leaflabs.com/ <blockquote><p>Windows works fine here :P</p> </blockquote> <p>Do you use MS Windows Thin Client?<br /> Does Maple work fine on it?</p> <blockquote><p>Sadly I don't have a UNO to try, but to be honest, can't see the point of moving to it.</p> </blockquote> <p>It was a test of using a 'driverless' USB serial device on MS Windows Thin Client.</p> <blockquote><p>btw, wasn't the USB Serial bootloader your most requested item ;P</p> </blockquote> <p>Yes.
