You need to download and install the correct driver for your particular board. If it isn't showing up in device manager than your PC has no way of communicating with it. If you don't already have a bootloader on the chip then you'll most likely need to get a programmer in order to do so.

I thought I would burn the bootlegger, and when I tried to do that I got avrdude: usbdev_open(): did not find any USB device "usb"

what should I do?

You have a driver issue if it isn't being recognized by your PC.

I know this is a common problem, but I'm frustrated because I can't solve it. I updated the firmware on my Melzi v 2.0 on Reprap Tricolor mendel, and when I uploaded it using Arduino, I got error message avrdude: stk500_getsync(): not in sync: resp=0x00.

The following things have been tried/verified:

-The correct COM port is recognized and selected both by arduino as well as the computer device manager
-Correct board has been selected under Tools menu in Arduino
-The USB has been unplugged, replugged
-Computer restarted, Arduino restarted
-USB cable reset on the board before, during, after upload

Still no luck. Arduino doesn't establish a connection. I'm also seeing that when I try to connect to pronterface (this is stupid of me), it does not connect to COM port in pronterface as well, so I'm trying to figure out the issue.
