I received recently some Uno version R3 in the mail (genuine ones).
They work fine on the Mac.
In response to a forum query I tried to demonstrate something under Windows XP, but I got a message about "device driver not detected".
Specifically: "Cannot install this hardware. The hardware was not installed because the wizard cannot find the necessary software.".
Even following the instructions on the official page about installing it did not work. This page:
I thought I was going crazy, but plugging in my older Uno, the instructions worked fine.
Is this something fixed in release 1.0? I'm reluctant to upgrade to that because of all the function renaming, and lots of libraries apparently not working with it.
Assuming (an assumption I don't make personally) that this is a known problem, could the web page be upgraded to alert people to this problem? Thanks.
Finally, navigate to and select the Uno's driver file, named "ArduinoUNO.inf", located in the "Drivers" folder of the Arduino Software download (not the "FTDI USB Drivers" sub-directory).
Now that is correct in a sense (that file is also there in the 1.0 download), it is misleading. For users of older downloads (like 0022, 0023) who may choose not to upgrade their IDE, the statement above implies that the file "ArduinoUNO.inf" is the one that is needed.
It would be helpful to add something like:
If you are using a newer board, like the Uno R3 (see revision number printed on the back of the board), you need more up-to-date drivers.
In the case of the Uno R3 the file is "Arduino UNO REV3.inf".
These drivers can be found in the Version 1.0 download of the IDE software. If you wish, or need, to continue using an earlier version of the software, you will still need to download Version 1.0 to locate the correct drivers in the "drivers" folder.
It might also be helpful (and save an 86 Mb download) if the drivers were made available independently (on the Downloads page, for example).
