atmega328p programming problem with avrdude

I’ve tried to compile and program with avrdude, but there is some problem

The environment is ubuntu 14.04,
avrdude-5.11.1
Hardware is chipwhisperer capture rev.2 (REV 2.1)

In the folder:
chipwhisperer/hardware/victims/firmware/

After modifying the makefile and compile,
it shows up the error message when avrdude programming:

avrdude -p m328p -P usb -c jtag2isp -F -U flash:w:simpleserial-aes.hex
avrdude: usbdev_open(): did not find any USB device “usb”

Does anybody know how to solve the problem?
Tks~~

Hello,

The device appears as an ISP Mk2, so you should be specifying a “avrisp2” instead of “jtag2isp”. Does it detect the device then?
