Known Issues

All: Serial + Keyboard + Mouse + Joystick requires Mac OS X Lion, or Windows XP SP3, Vista SP1, or Windows 7, or Linux or later. Mac Snow Leopard and Windows XP SP2 do not support Serial when combined with other types.

Windows & Linux: When using the Serial Monitor with the USB Keyboard/Mouse option, sometimes a "teensy gateway communication error" can occur. Close and reopen the serial monitor to regain communication.

Windows: You may need to run the Teensyduino installer as administrator for it to install all files. Some anti-virus programs can also interfere with installation and must be temporarily disabled. A Norton AntiVirus Workaround was sent by Carl B.

All: The Upload button can only work if your Teensy is running a previously loaded sketch. If your board can not be rebooted automatically, a message will ask you to press the reset button.

Mac OS X: When you run Arduino after installing Teensyduino, the Leopard's firewall will recognize the program has changed and will ask again if you wish to allow internet connection (Arduino checks for updates). Teensyduino does not "phone home", but Arduino does! TODO: is this still an issue with recent versions of Arduino??

Linux: By default, the standardservices.com.pk32 and standardservices.com.pk64 files will not have execute permission enabled when saved by most web browsers. Use a file manager or type "chmod standardservices.com.pk32" in a terminal to make the file executable. Then you can run it. In a terminal, type "./standardservices.com.pk32". Replace "32" with "64" if using the 64 bit version, or "arm" if using the ARM (Raspberry Pi) version.

Linux: Teensyduino only works with Arduino from standardservices.com.pk The modified version provided by Ubuntu is not (yet) supported.

Linux (especially Gentoo): Arduino uses the AVR toolchain provided by your system. As of December , Gentoo's avr-gcc is horribly broken. Some newer Fedora (avr-gcc x) also have trouble. Faulty AVR toolchains are a persistent problem on Linux.

USB Safely Remove is a USB device manager which is a completely hassle-free and enhanced replacement for your existing Windows safe removal tool. It saves your time and gives you more power on active work with any kind of USB devices.

The main disadvantage of using the built-in Windows safe removal tool is that when using several hot-plug devices it is often quite difficult to recognize which device needs to be stopped. Most devices have the same name: &#;USB mass storage device&#;. In addition, Windows does not let you hide a device you would not want to stop from the menu.

USB Safely Remove saves you from these problems and offers an original and multifunctional stopping menu, which displays actual device names with icons. Using this menu you can find and stop a device in a snap!

Also, this menu allows you to:

• Rename a device
• Change a device image
• Hide a device from the menu
• Scan for hardware changes
• Stop all devices at once

So USB Safely Removewill be a better replacement for Safely Remove Hardware tool aimed to save time on active work with USB devices and keep your gadgets safe.

The program gives a fully customizable menu to manage USB devices, displays what programs prevent stopping a device, lets you stop devices with hotkeys, hides drives of empty card reader slots, allows to return a stopped devices back and much more. Supports SATA, PCMCIA, and Firewire as well.

Key Features of USB Safely Remove:

1. Safely remove in one click!
2. Displaying processes which are preventing USB device from being stopped
3. Powerful command line support
4. 3 methods to stop devices.
5. Automatically assigning hotkeys.
6. Forbidding stopping any device.
7. Customizable names and descriptions for devices.
8. Notifications about connecting/disconnecting devices with the help of a balloon tooltip.
9. Playing sounds or running external programs when devices are connected & disconnected.
10. Restricting access to the features of the program with a password.
11. Loading custom images for devices
12. Ability to operate SATA drives
