USB device not found?

Post by axos88 »

Under windows, it says that "USBTiny device found", and it appears in the device manager (even though i don't know if the device is acutally found, or only the driver is loaded...), but i can't communicate with it using avrdude.

So i tried to do it under linux, but the device doesn't even get found:

avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)
