I bought the following USBasp off of Aliexpress.
The Arduino UDE doesn't recognize it. When I try to run avrdude with it, it says:
avrdude -cusbasp -Pusb -patmega328p avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor='www.fischl.de' product='USBasp'
Looking at the USB enumeration, it says:
Product ID: 0xc8b4 Vendor ID: 0x03eb (Atmel Corporation) Version: 1.00 Speed: Up to 1.5 Mb/sec Manufacturer: zhifengsoft Location ID: 0x14200000 / 8 Current Available (mA): 1000 Current Required (mA): 100 Extra Operating Current (mA): 0
Looking online, I see one blog post (http://www.sciencetronics.com/greenphotons/?p=938) about a device with the same VID/PID, and it says it can be reprogrammed but is not clear how to do it.
In particular, I know there is a jumper that I need to set to put it in self-programming mode but I can't figure out where to put this jumper. Once the jumper is in, I understand I just match the SPI pins and program it using the firmware.
Can someone help?
