Dear AVRDUDE-Team, I've been trying to get into contact with my ATmega168P for a while and, obviously, am having trouble: I use AVRDUDE for Mac, with a ISP-programmer of DIAMEX, which is connected to a USB-Port. Each time I try to do something with my microcontroller, (e.g. avrdude -c stk500v2 -P usb -U flash:v:/Users/linusgeiser/Desktop/try.hex:i -p atmega168p) AVRDUDE responses me with �avrdude: usbdev_open(): did not find any USB device "usb"�. The programmer is recognised by the computer (at least the system profiler says, that there is a AVR-ISP connected to a USB-port). The programmer is connected correctly to the microcontroller (or at least that's what I hope: the programmer has a output with six pins (+5V/GND/MISO/MOSI/RESET/SCK) which are connected to the coresponding pins of the controller (GND twice to GND, +5V to VCC, AVCC and AREF, as I have seen it on some website)). My guess is that the communication between the programmer and AVRDUDE somehow doesn't work. I would be very grateful if you could help me! Just as a warning: I am a total beginner on the field of microcontroller (so you can assume that I have made any possible mistake) and my native tongue is not englsh (it's (swiss) german). Thanks and best regards, Linus
