Re: [Paparazzi-devel] Upload firmware-Device no found(Lisa/M 2.0)

[Gareth Roberts]

Hi Chen,

Restarting the machine will restart udev.
From the dmesg log, it looks like your Lisa is being detected and that  
you've unplugged and plugged it in a few times.

The most likely problem, as Tilman has said, is permissions.

Also, ensure you've installed the python-usb package.

Cheers,
Gareth
