Arduino with FTDI cable - USB port error

This is my first time using FTDI with Arduino.

I'm using the SparkFun EL Sequencer which uses and embedded ATMega328p. I hooked it up to my USB port using this FTDI cable. When I try to upload my code: I get the following error:

avrdude: stk500_getsync(): not in sync: resp=0x00


Debug mode:

avrdude: usbdev_open(): did not find any USB device "usb"


I've used my regular USB cable to successfully program my UNO from this machine (Win 7) before. No problem there.

With the sequencer I see the machine detecting a connection on COM 7 when I plug in the new device. I've tried pressing RESET on the Arduino prior to uploading, which I've seen in some other posts.

Am I missing something here? The description of the cable seems to imply that I don't need any other hardware.

• This FTDI cable is a USB to serial port converter. Which means you'd be trying to program your Arduino through its serial port, not USB. Is that what you're trying to do? – MandoMando Mar 17 '13 at 23:43
• avrdude calling a function named usbdev_open() sounds a lot like an incorrect command line. As far as AVRdude is concerned, your device is serial, not USB. – Chris Stratton Mar 17 '13 at 23:44
• @ChrisStratton btw, multi +1s for the helpful comments and not casting a down-vote. side-bar discussion from here. – MandoMando Mar 17 '13 at 23:47
• Mando: I assumed because the cable had a USB connector on the other end that it would work. I have the FTDI driver installed on my machine for my old UNO, via usb. As to usb/serial - I just press the upload button, not sure. – Diodeus - James MacFarlane Mar 18 '13 at 0:03
• Try the same settings you use with the uno, or even better, try those for duemilanova. Your error strongly suggests something else was used. FYI the Uno does not use the FTDI driver. – Chris Stratton Mar 18 '13 at 13:55
