AVR Freaks

I'm trying to program an ATmega162 using my 51 AVR ISP programmer.  When I run avrdude, I get this error:

C:\Program Files (x86)\Atmel Studio\AVRDude>avrdude -p m162 -c usbasp -P USB -U "flash:w:""F:\Files\Dev\EE\BeerGoat\Test1\Test1\Debug\Test1.hex"":i" -vvv
avrdude: invalid file format 'i -vvv' in update specifier
avrdude: error parsing update operation 'flash:w:"F:\Files\Dev\EE\BeerGoat\Test1\Test1\Debug\Test1.hex:i -vvv'

C:\Program Files (x86)\Atmel Studio\AVRDude>avrdude -p m162 -c usbasp -P USB -vvv -U "flash:w:""F:\Files\Dev\EE\BeerGoat\Test1\Test1\Debug\Test1.hex"":i"

         Using Port                    : USB
         Using Programmer              : usbasp
avrdude: error: could not find USB device "USBasp" with vid=0x16c0 pid=0x5dc

avrdude done.  Thank you.

I'm not sure why avrdude is failing to find the device.  I used Zadig to install the driver (as documented here) and Windows can see it just fine (with the correct VID and PID).

I'm running Windows 7 64-bit, but I turned off UAC and the like for this test.  I didn't run into any hiccups installing the driver.  Avrdude is running with administrative privileges and should have no problem enumerating USB devices.  

Any suggestions?
