Hello, I am using an ebay USBasp programmer since several months but I would like to build my own USBasp for fun. I build the firmware available in [1]. Then, I flash the memory of an ATMEL ATMEGA8 using avrdude and my ebay USBasp programmer. After that, I follow the schematics available in [1]. Finally, I connect my USB cable and an other ATMEL ATMEGA8 to my breadboard then I try my new USBasp programmer.
When I connect my USBasp programmer I got this*: [20334.276595] usb 2-1.5: new low-speed USB device number 12 using ehci-pci [20339.367470] usb 2-1.5: New USB device found, idVendor=16c0, idProduct=05dc [20339.367481] usb 2-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [20339.367484] usb 2-1.5: Product: USBasp [20339.367487] usb 2-1.5: Manufacturer: www.fischl.de If I call avrdude I got this**: avrdude: Warning: cannot query manufacturer for device: Connection timed out avrdude: Warning: cannot query product for device: Connection timed out avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor='www.fischl.de' product='USBasp' avrdude done. Thank you. This is a photo of my breadboard: http://yugiohjcj.free.fr/usbasp.jpg I am wondering if you can guess what could be the problem. Any idea ? Thank you. Best regards.
