Is this the same computer? If not, it may be a hardware problem, e.g. missing zener diodes.

Hi all
After googling for a day I found out the problem was permissions. I should call avrdude as root!!! really crazy problem!


Code: Select all

 sudo avrdude -c usbasp -p m8

This depends on your Linux configuration. As far as I know, you can configure hotplug to set less restrictive permissions for particular USB devices. By default, only root has full access.

add permission to your usb device.

Hi all, with christian suggestions and some googling I used these simple instructions for adding permissions to users for using usb device:


How to add user permission for USBasp (I have tested this method in ubuntu 7.10):
source:http://www.bitpim.org/help/

1. Create new rule for udev

Code: Select all

sudo gedit /etc/udev/rules.d/60-objdev.rules

2. Edit new rule in gedit and add following:

Code: Select all

   SUBSYSTEM!="usb_device", ACTION!="add", GOTO="objdev_rules_end"
   # USBasp
   SYSFS{idVendor}=="16c0", SYSFS{idProduct}=="05dc", GROUP="users", MODE="666"
   LABEL="objdev_rules_end"

3. Restart udev.

Code: Select all

   sudo /etc/init.d/udev restart

In Ubuntu 12-04 LTS udev rules using SYSFS do not work. ATTRS(..) do work.
