Okay - I’ve been banging my head against the wall for too many hours now trying to get dfu-util working without sudo.
My reasons for wanting this are:
- I use nvm, which doesn’t seem to play very nice with sudo, so
sudo particle flash --usbrequires I configure my “sudo path” to point to the particular instance of node I’m running. - I’m calling dfu-util from within a python script (via subprocess.call) that I wrote to streamline product setup and testing. The script does other things, and everything gets messy because dfu-util needs sudo.
I installed dfu-util v0.8 using homebrew on a Mac running Yosemite, and out of the box it didn’t require sudo.
I also managed to configure my chromebook in dev-mode running Crouton (with Ubuntu 14.0.4) to not require sudo… Unfortunately, I didn’t think too much of this at the time. So I’m not 100% sure, but I’m pretty sure it was as easy as just adding my user to a couple groups (dialout, serial, usb).
However, I’m not having the same luck on my work machine (running Ubuntu 14.0.4). I’ve got dfu-util v0.8 up and running, but I can’t configure it to not require sudo. I’ve added myself to “dialout”, however neither the “serial”, nor “usb” groups seem to exist (they may have been a Crouton thing).
I assumed it would be as easy as:
ls -l /dev/<myPhotonInDfuMode>
Then just adding myself to whatever group has permission, but the Photon doesn’t seem to show up in /dev in dfu-mode.
I’m now trying with lsusb which let’s me see the device… I’m going to keep tinkering, but I figured I’d ask on the forums in case anyone has already solved this.
