/media directory on my machine

0 votes

With no camera and no other devices connected I have a /media/jack/JEVOIS entry in my system.

When I plug the camerea in I get a /media/jack/JEVOIS1 entry,  Is that correct?

I ask this because when I run jevois-usbsd stop.  I get an error messages as below.

Any ideas what to do?


jack@jack-ubuntu:~$ jevois-usbsd start

Cannot access /dev/ttyACM0 -- is JeVois plugged in? -- ABORT

jack@jack-ubuntu:~$ jevois-usbsd start

Camera usbsd command ok but /media//JEVOIS not found -- ABORT

jack@jack-ubuntu:~$ sudo jevois-usbsd start

Camera usbsd command ok but /media//JEVOIS not found -- ABORT

jack@jack-ubuntu:~$ sudo jevois-usbsd stop

eject: unable to find or open device for: `cdrom'

Error releasing /media//JEVOIS -- ABORT

something went wrong, maybe you tried to save to SD when there was no SD and so now a regular directory /media/jack/JEVOIS was created. You should delete it, usually in /media you only want directories created on the fly by the system as you insert hardware. For that:

- disconnect flash card, jevois camera, etc

- rmdir /media/jack/JEVOIS       (may need sudo)

- you may have to reboot your host so it won't want to use JEVOIS1 anymore

from this error you mentioned: "Error releasing /media//JEVOIS -- ABORT"

it looks like your username is not being detected by our scripts. It should have your username (jack) between "media" and "JEVOIS". We used the unix command logname to get the user name, but maybe we shoud use variable $USER instead. Can you please report what you get when you type, in a terminal:



echo $USER
