AVR-ISP-MKII & AVRDUDE

[biba]

Hi,

I updated the device this way:

Code Select Expand

# dfu-programmer at90usb162 flash libUSB-AVRISP-MKII.hex
Validating...
10288 bytes used (83.72%)

unplug & plug

Code Select Expand

usb 3-3: USB disconnect, device number 16
usb 3-3: new full-speed USB device number 17 using ohci_hcd

Now there is a red/orange LED. But nothing work 

How can I verify if the update is successfull ?
