I'm trying to flash my Galaxy S but it's not working.

This step from the wiki:


On the computer, open terminal and run the following command from the Heimdall directory: heimdall flash --kernel zImage

I get this error: Failed to access device. libusb error: -12

What can I do?

Thank you.

This maybe a  permission problem, I had this also on SSG2


sudo chmod 666 /dev/bus/usb/00?/00?    in terminal with 00?'s changed to suit your device

then try again
