If you buy a cheap USBasp V2.0 ICSP programmer on eBay, chances are, avrdude will give you the following warning message:
To get rid of this warning, you must update the firmware to the latest version: usbasp.2011-05-28.tar.gz. If you have another ICSP programmer already, such as a USBtinyISP, programming in the new firmware is quite simple. Here are the steps: 0. Verify that you have a USBasp V2.0, and that it has a 12MHz crystal and an ATMEGA8 or ATMEGA8A MCU. When I connected the USBASP to my Uno and tried this with a sketch, the upload failed with the error: avrdude: warning: cannot set sck period. Please check for usbasp firmware update Known problem, ol d firmware. Sigh, another job to do. This is what I did to make it work as wanted. Some googling around and this is my recipy.
Usbasp Avr Programmer Driver
avrdude: warning: cannot set sck period. Free easy animation software for mac. please check for usbasp firmware update.
Cheap USBASP programmer which you china buy on ebay, ali and others. Official project WebPage: JP1 – Supply Target – Choose between 5V and 3.3V. JP2 – Self Program – jumper on for self.
While it’s just a warning message, it’s still a constant irritant. To get rid of this warning, you must update the firmware to the latest version: usbasp.2011-05-28.tar.gz
If you have another ICSP programmer already, such as a USBtinyISP, programming in the new firmware is quite simple. Here are the steps:
0. Verify that you have a USBasp V2.0, and that it has a 12MHz crystal and an ATMEGA8 or ATMEGA8A MCU onboard. DO NOT CONNECT IT TO THE USB PORT OF YOUR COMPUTER.
1. Short the JP2 (self-programming) jumper.
2. Connect the USBasp V2.0 to the USBtinyISP using a 10-pin ribbon cable
3. Reprogram the USBasp’s fuses: avrdude -c usbtiny -p atmega8 -u -U hfuse:w:0xc9:m -U lfuse:w:0xef:m

4. Flash in the new firmware: avrdude -c usbtiny -p atmega8 -U flash:w:usbasp.atmega8.2011-05-28.hex
Note that the usbasp.2011-05-28.tar.gz archive doesn’t contain a compiled .hex file, so you have to re-compile it using WinAVR. Instead, you can just use my hex file, which I compiled directly from the sources: usbasp.atmega8.2011-05-28.zip
How To Check Usbasp Firmware Version For Pc
If you don’t have another ICSP programmer to use, you can use an Arduino, following these instructions: Updating firmware on USBASP bought from eBay. However, you may have to also set the fuses according to my Step (3) above. My PC wouldn’t recognize the reprogrammed USBasp until I set the fuses.
