Re: [avrdude-dev] avrisp mk II in linux

[Naveen Goswamy]

Hello,

Thanks for your response,


I tried using

$ avrdude -p t2313 -c avrisp2 -P usb

and received

avrdude: usb_open(): cannot read serial number "error sending control 
message: Operation not permitted"
avrdude: usb_open(): cannot read product name "error sending control 
message: Operation not permitted"
avrdude: usbdev_open(): error setting configuration 1: could not set 
config 1: Operation not permitted
avrdude: usbdev_open(): did not find any USB device "usb"



I have set udev to enable permissions 0666 as in:

$ ls -al /dev/bus/usb/002/006
crw-rw-rw- 1 root root 189, 133 2006-12-20 16:12 /dev/bus/usb/002/006

and my udev rule is:

BUS=="usb", ACTION=="add", SYSFS{product}=="AVRISP mkII", \
MODE="0666", SYMLINK+="avrdev"


Sorry if I am missing something fundamental, I'm just starting out :)
