USBasp is an ICSP (In Circuit Serial Programming) adapter that allows you to install new bootloaders and firmware on common AVR microcontrollers, such as those used in Arduino-compatible boards.
The board you will be programming is referred to as the 'target'.
Usbasp, ubuntu 14.10 could not find usb device. Usbasp device programmer software v.2.4.0 a windows based gui for popular avrdude command line utility for avr microcontroller has got many features with a lightweight easy to understand otnet and avrdude is provided with s only usbasp programmer but. 2 plug your usbasp programmer into the usb port.
Installing driver: Step1: Connect USBasp to USB port of your computer. New hardware found dialog box will appear.In this select ‘Install from a list or specific location’.Click ‘Next’. Step2: – Select ‘Don’t search ’ – Click Next Step3: – Click ‘Have Disk’ Step4: ‘Install from disk’ dialog box will appear. There are 3 tested methods to install the usbasp driver for windows 7. One is using the driver signature enforcement override method, the other is directly editing the.inf file & the third one i have explained below. This worked for me when the first two failed.
Board Features
For typical usage you can leave the USBasp configured exactly as it comes in the packet. For specific uses you may need to change some of these settings.
Micro USB socket. Connect to your computer using the cable supplied.

Target voltage selection. The USBasp supports target boards running at either 5V or 3.3V. Most Arduino-compatible boards operate at 5V. Place the switch in the appropriate position for the board you will be programming.
'Program' jumper. If you short out this jumper, the USBasp goes into a special mode that changes it from being a programmer to being a target. This is to allow you to update the firmware on the USBasp itself using another programmer.
Target power jumper. With this jumper in place the USBasp will supply power to the target via the ICSP header. This is usually desirable. However, if the target is powered independently (such as through a DC jack or USB connection) you should remove this jumper.
ICSP header to target. The programming output of the USBasp, which you connect to the target's ICSP header using the supplied cable.
'Slow Clock' jumper. If you short out this jumper, the USBasp will operate at a lower speed to maximise compatibility with some targets. Not generally required unless you're programming brand new AVRs (see below.)
Status LED. Shows power, write, and active statuses.
Connecting Hardware
1. Disconnect your target board from other power sources, unless you have specific requirements to power it independently during programming.
2. Connect the USBasp to your computer using the supplied USB cable.
3. Connect the USBasp to your target board using the supplied 6-way cable.
WARNING: Pay special attention to the orientation of the cable. You will see that one side of the cable has a red stripe, to indicate which end is pin 1. The USBasp has a dot next to the ICSP header at the pin 1 end, and your target board should also have a marking next to pin 1. Connect the cable so that the side with the red stripe is closest to pin 1 on both the USBasp and the target. On most targets this will naturally fall into place if you lay the boards down so they are facing you as shown below.
Windows Drivers
Linux and OS X users can skip this section (although if you're a Linux user, make sure to read the Permissions on Linux section at the bottom of this page.)
Windows requires a generic USB driver in order to communicate with the USBAsp. A tool called Zadig makes it easy to install this driver.
- Unplug the USBasp.
- Download Zadig from http://zadig.akeo.ie/. Note there are separate versions for Windows XP or newer versions of Windows.
- Launch Zadig and then plug in the USBasp. Cancel any Windows dialogs that pop up.
- Set up the Zadig dialog as follows, check the highlighted fields:
- 'Usbasp' selected in the main dropdown (this should appear automatically when you plug in the USBasp. If you don't see it in the list, select 'List All Devices' from the Options menu in Zadig.
- libusb-win32 as the driver type (use the small up/down arrows to select this entry.)
- Click 'Install Driver' and wait for the driver to finish installing.
- You're done with Zadig, time to use your USBasp!
Use From Arduino IDE
Important note: Unlike many other boards and programmers, USBasp doesn't appear as a USB serial port. Therefore there isn't a port listed under 'Tools > Serial Port' in the Arduino IDE, or other places. This is normal.
Installing New Bootloader
The Arduino IDE includes bootloaders for various supported boards. Connect your computer, USBasp, and target as shown above, then launch the IDE and use the following menu items.
1. Select Tools > Board and select the board type that matches your target.
2. Select Tools > Programmer and select 'USBasp' as the programmer type.
3. Select Tools > Burn Bootloader. The Arduino IDE will then install the bootloader onto your target board.
Installing A Sketch
Normally sketches are installed via the USB port on your Arduino, but you can also install them directly using the USBasp which bypasses the bootloader and USB connection. With your sketch open, use the following menu items.
1. Select Tools > Board and select the board type that matches your target.
2. Select Tools > Programmer and select 'USBasp' as the programmer type.
3. Select File > Upload Using Programmer. The Arduino IDE will then compile and upload your sketch onto the target board.
Use from command line
The command line tool avrdude can also be used to program AVRs. This is a more complex tool than programming via the Arduino IDE, but much more flexible.
The programmer argument to use avrdude with a USBasp is -c usbasp.
You can install avrdude for Windows as part of the WinAVR package or for OS X as part of AVR CrossPack. Linux users can usually install it as part of their distribution’s package management system.
For example, to use avrdude to read the status of the ATMega328P on a Freetronics Eleven board:

For standalone GUI-based programming tools on Windows, check out Khazama AVR Programmer or eXtreme Burner - AVR. eXtreme Burner also works on Linux.
Programming Brand new AVRs
By default, the USBasp programs the target with a “programming clock” of 375kHz. This makes for fast programming, but only works if the AVR chp is configured with a clock of at least 1.5MHz.
Brand new AVR chips usually come configured from the factory with an internal clock of 1MHz. This is set as part of the “fuse bits” inside the microcontroller. If you use the Arduino IDE it gets reprogrammed to use the external 16MHz crystal when you upload the Arduino bootloader.
The symptoms of trying to program an AVR with an overly fast programming clock are the same as when no AVR is connected at all:
There are two ways around this problem.
Set the “Slow Clock” jumper
This is the best option if you are using the Arduino IDE to program firmware onto brand new AVRs.
Bridging across the slow clock jumper lowers the programming clock to 8kHz, slow enough for AVRs running at just 32kHz.
You can install a jumper header in the two jumper holes, or if you only use it occasionally you can get by with just using a piece of wire or even a pair of tweezers!
Set the clock in software
This is the best option if you are using avrdude on the command line. Avrdude’s -B option allows you to set the programming clock speed from software, no jumper required!
The option -B 4 will set a programming speed of 187.5kHz, still fast but slow enough for a brand new 1MHz AVR.
Usbasp Driver Windows Xp Professional
For example, to read the configuration of a brand new ATTiny85:
If you need an even slower programming clock, just keep increasing -B. The maximum -B 64 yields an 8kHz programming clock, same as if the “slow clock” jumper was installed.
Note that -B is ignored entirely if the “slow clock” jumper is installed.
Permissions on Linux
Linux users may encounter an error like 'error sending control message: Operation not permitted' when trying to use the USBAsp. This is because by default normal users don't have access to USB devices.
A temporary workaround is to run the operation as root, using sudo or su. A much better solution is to tell Linux that you want all users to be allowed to access the USBAsp. This is done by creating a udev rule. The specifics of creating udev rules vary a bit depending on which Linux distribution you are using, however there is usually a directory /etc/udev/rules.d which contains files with custom rules. As root, create a new file in that directory called 'usbasp.rules' with the following single line of content in it:
SUBSYSTEMS'usb', ATTRS{idVendor}'16c0', ATTRS{idProduct}'05dc', MODE='0666' Then restart the udev service, by running a command like this:
sudo /etc/init.d/udev restart
Today I came across a surprisingly simple approach to installing USBasp and USBtiny drivers for all versions of Windows — XP, 7, 8, 8.1, whether 32-bit or 64-bit, all inclusive! As you may know, installing open-source drivers such as USBasp and USBtiny have been a great pain on some of the recent Windows OS, due to the enforcement of signed drivers. The typical solution involves rebooting Windows into a mode that disables driver signature enforcement. Even after you’ve done it once, if you boot into the normal mode next time, it may fail to recognize the driver again (reporting it’s not digitally signed). A huge source of frustration.
Anyways, while searching for ‘fully signed USBasp driver’, I came across this tool called Zadig, which can be used to install libusb drivers on all versions of Windows, and it’s digitally signed. Since USBasp and USBtiny are both based on libusb, could it be the right solution? To my great surprise it worked really well — I was able to install both drivers on Windows XP, 7 (32-bit and 64-bit), 8, and 8.1 instantly, without messing with driver signature enforcement at all. I was mostly surprised such a great solution wasn’t documented more widely online.
Instructions
Usbasp Driver Windows Xp 64
- Go to http://zadig.akeo.ie/ and download the software (note that Windows XP has a separate link).
- Plug in your USBasp or USBtiny device. In case your microcontroller uses a USBasp or USBtiny bootloader, enter bootloading mode, and let Windows detect the device (it will report driver not found). If a window pops up asking to search for driver, just close it or click on Cancel.
- At this point, run Zadig, it should detect the USBasp or USBtiny, or any libusb device that you have. Then in the selection box (see below), choose libusb-win32 (v1.2.6.0), and click on Install Driver, and wait for the installation to complete.
That’s it! Because the drivers are digitally signed, there is no hassle installing it in Windows 7 64-bit and Windows 8.1.
I will be updating the driver installation instructions for OpenSprinkler 2.1 and SquareWear right away, as they both use USBasp bootloader. Users have often complained that it’s frustrating to install USBasp driver for Windows 7 64-bit and Windows 8.1. Those days are now past!
