Hi,
I have an unused Arduino Ethernet R3 unit. Now while I'm trying to upload a sketch to it, I get the following error message: avrdude: usbdev_open(): did not find any USB device "usb". The correct board is selected, the correct port is selected and the ON led is light when the FTDI cable is connected. Pressing the reset button does not seem to do anything. I tried to reinstall the drivers and update the Arduino programmer. Any suggestions?
OS Win 7 64
Arduiono 1.6.8
IDE 1.6.5
Unfortunately that did not solve the issue.

How are you trying to do the upload? That error usually occurs when you are doing Upload Using Programmer or Burn Bootloader.
This I should have included into the initial post.
The above error message appears when pressing shift and clicking upload at the same time.
If I only click upload, I get the following error message:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xe3
There isn't anything else connected to the baord except the FTDI cable.

That does an Upload Using Programmer. That is for use with an external ISP programmer so if you're using an FTDI then you should do a normal upload. Why are you using an FTDI cable to upload to your Arduino Ethernet? Why not use the USB port on the board instead?
There is no USB port on Arduino Ethernet, only Ethernet, ISCP and FTDI.
Ah, didn't realize that. I know some FTDI cables don't have the DTR line which is used for automatic reset so this means you have to manually reset the Arduino to upload but it sounds like you're already doing that.
