Need help! Trying to establish connection, but failed..

Post by IloveIphonyWikyBolex » Sun Jan 08, 2012 12:11 am

Hello community,

I've been trying to get the HID MOUSE example working from the v-usb package, but it's not working for me.

I have a ATmega162-16PU and I just can't establish an usb connection. My laptop says it's found "a unknown device". I've been working for days now to find the problem, but i just cant find it. it'll be great if someone could help me.(Maybe it's my fuses that are not set right, but i'm not so sure, since i already broken a ATMEGA32-16PU with the wrong fuses...)

Could someone check if my fuses are right and check the code? As I don't have much time left till my deadline...

Anyways Thanks!

This is a picture of my current breadboard, i'm trying to follow this guide(With the HID Bootloader), but no luck(The blue lines are the connectors for ISP programming):

I normally upload the .hex file with "Mysmallusb Light" and with the program: "myAVR_ProgTool"(ISP Programmer), as i don't know how to upload with Avrdude though STK500 with COM1 port(referring to the ISP programmer mentioned earlier).

This is my makefile

Maybe I'm mistaken but I'm not seeing the pull up resistor to D-? It's R3 in this schematic: http://www.obdev.at/Images/vusb/circuit-zoomed.gif
It's very important for it identifies the device as a low speed device.

I made a mistake by putting the 1.5k resistor on a different breadboard line, than putting the same line with the cable underneath the resistor. I'm going to fix this when I get home.

Can anyone check if the fuses are right for this device? because I don't want to break another IC.

You cannot "break" an AVR with wrong fuses. The only 2 things you can do that cause problems:
-Disable ISP (however, this is only available when using high voltage programming)
-Set an external crystal without having one connected
