luafv and fileinfo are Microsoft and should be okay. I have those on mine and are not causing any problems.

eamonm is ESET Anti-Virus

SbieDrv is Sandboxie

The Rapport stuff looks like it is something for online banking:

47  Using Arduino / Installation & Troubleshooting / Re: Compilation became incredibly slow on: June 17, 2013, 10:15:08 am
Here are a couple of causes for slow compiler performance. These are not the only causes.

1) Disable/Uninstall Anti-Virus, Firewall software, and any other application that installs a file system filter driver.

You can use fltmc.exe from a command line to get a list of running File System Filter Drivers on your machine.

Here are some explanations of why these will impact performance:

"Another common cause of poor I/O performance is if a file system filter driver has been installed. A filter driver intercepts requests before they reach the file system, and performs additional processing such as anti-virus checking and encryption. It goes without saying that this can only have a negative impact on I/O performance."

"To understand why a filter driver can slow things down you need to understand that a filter driver basically installs itself between the application and the underlying file system and intercepts nearly every call being made to the underlying I/O subsystem.   Most of the time filter drivers are just fine and run with no problems at all.   However, what do they do?  An antivirus filter driver may have several tasks that it needs to do for each I/O.  This may involve looking up information about a process or file when it's being accessed.   If the data source associated with this information changes it can change the amount of time that these operations take.   The interesting thing is that the timing change may only be a hundred or so extra milliseconds per call to the registry or file system.  Under most cases a user would not even notice this.  If however you have some aspect of your application needs to make many thousands of calls and they each take 250+ milliseconds vs. 10 milliseconds, all of a sudden the problem compounds.  The classic example of this is a VIRUS PROFILE gets uploaded or pushed to servers and all of a sudden the customer starts seeing performance problems because the data set or comparison for the filter driver changes."

2) If you have PATA drives, CRC errors will cause Windows to fall back to a slower DMA mode or PIO mode. CRC errors can be caused by a bad cable or the HDD may be about to fail.

Check IDE port settings in Device Manager.

48  Using Arduino / Installation & Troubleshooting / Re: Problem with Arduino Leonardo, the device is not recognized on: June 17, 2013, 09:13:54 am
To load a new sketch on your Leonardo:

Hold the reset button and continue to hold while selecting Upload.
When the IDE shows Uploading...
Release the reset button.

Try this with Blink or some other known good sketch.

Is this a genuine Arduino Uno?
If not, it might not have the Uno/optiboot bootloader.

Try one of the other board selections, like Duemilanove.

51  Using Arduino / Installation & Troubleshooting / Re: Cannot update code on MaKey MaKey on: June 14, 2013, 12:10:41 pm
It looks like driver installation did not work properly for the bootloader.

The MaKey MaKey shows up as two different devices, one when it is running a sketch and another when it is running the bootloader.

Try the driver installation process while the bootloader is running. When you see " "MaKey MaKey Bootloader" shows up in the device manager with a little yellow alert "!" icon "

Right click the MaKey MaKey Bootloader in Device Manager
Select Update Driver Software
Select Browse my computer for software
Click Browse button
Select the folder that contains the MaKey MaKey.inf file
Click OK
Click Next

You are using the java that is bundled with the IDE.

I don't think that is the cause of your problem.

I know that doesn't help much, but at least you can rule that out.
53  Development / Other Software Development / Re: Arduino 1.5.2 command line build on: June 13, 2013, 10:35:19 am
What OS?
54  Using Arduino / Installation & Troubleshooting / Re: Compilation became incredibly slow on: June 13, 2013, 10:16:09 am
If you think Java might be the problem, you can see which version of Java is being used by running this from a command line in your arduino directory:

arduino --l4j-debug

This will create a launch4j.log file in your arduino directory.

It should look something like this:
Code:
CmdLine: C:\arduino\arduino-1.0.4\arduino.exe --l4j-debug
WOW64: yes
Working dir: C:\arduino\arduino-1.0.4\.
Bundled JRE: java
Check launcher: C:\arduino\arduino-1.0.4\java\bin\javaw.exe (OK)
Add classpath: lib\pde.jar
Add classpath: lib\core.jar
Add classpath: lib\jna.jar
Add classpath: lib\ecj.jar
Add classpath: lib\RXTXcomm.jar
Launcher: C:\arduino\arduino-1.0.4\java\bin\javaw.exe
Launcher args: -Xms128m -Xmx128m -classpath "lib;C:\arduino\arduino-1.0.4\java\lib\tools.jar;lib\pde.jar;lib\core.jar;lib\jna.jar;lib\ecj.jar;lib\RXTXcomm.jar" processing.app.Base
Args length: 164/32768 chars
Exit code: 259

Look for the lines that start with:
Bundled JRE:
Check launcher:
Launcher:

This will help indicate if you are using the Arduino bundled Java or your installed Java.

56  Using Arduino / Installation & Troubleshooting / Re: Arduino UNO R3 Not entering DFU Mode on: June 12, 2013, 09:09:15 am
I mis-understood your question.

Here are some examples of ISPs for AVR:
http://www.pololu.com/catalog/product/1300 (This is the one I use)
https://www.sparkfun.com/products/9825
http://www.adafruit.com/products/46
57  Using Arduino / Installation & Troubleshooting / Re: Arduino UNO R3 Not entering DFU Mode on: June 12, 2013, 07:25:53 am
You can use the working Arduino as a programmer and try to reprogram the USB to Serial device on the non-working one.

You can follow this tutorial for using the ArduionISP sketch:
http://arduino.cc/en/Tutorial/ArduinoISP

The firmware you want to load on the 16u2 is located in your Arduino software package:
arduino\hardware\arduino\firmwares\atmegaxxu2\Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.hex

You will need to connect the ArduinoISP to the six pin header located in the upper left hand corner, near the AREF label.
58  Using Arduino / Installation & Troubleshooting / Re: Arduino UNO R3 Not entering DFU Mode on: June 11, 2013, 09:54:00 pm
It's possible that the DFU bootloader is not in the flash.

The only way to reliably update the firmware is to use an ISP programmer or another Arduino as ISP programmer.

Do you have access to either of these?
59  Using Arduino / Installation & Troubleshooting / Re: Using Uno R3 on Linux? on: June 11, 2013, 08:58:55 pm
It is supported in 0.6.1

60  Using Arduino / Installation & Troubleshooting / Re: Using Uno R3 on Linux? on: June 11, 2013, 10:27:27 am
Have you tried using "atmega16u2" with dfu-programmer?

The device IDs are different between a at90usb162 and atmega16u2.
