[Errno 13] Permission denied: '/dev/cuaU0'

[kl7af]

Using the latest build of FreeBSD - all updates have been applied.

I have installed Chirp - a software application that allows a computer to program frequenceis to a handheld radio using a USB cord for communication.

When attemtping to use the Chirp software - I get the following error
$ [Errno 13] could not open port /dev/cuaU0: [Errno 13] Permission denied: '/dev/cuaU0'

I am guessing that the specified port needs to be given permission for access (read/write) - or something to that effect.

How would I accomplish this?

Thanks !

You use `ls -l` to find out which group has access to the device, then you add your user to that group.

and if you need to change the permission of a device file, you can use a devd script. Here is an example

root@kg-core2:~ # cat /usr/local/etc/devd/picoprobe.conf
# allow group (operator) to access the usb connection of Raspberry Pi picoprobe
notify 100 {
        match "system"          "USB";
        match "subsystem"       "INTERFACE";
        match "type"            "ATTACH";
        match "vendor"          "0x2e8a";
        match "product"         "0x000c";
        action "usb_devaddr=`echo $cdev | sed 's#^ugen##'` && chmod g+rw /dev/usb/${usb_devaddr}.*";
};

see devd.conf(5) for more.

dear kl7af :
add your current user to dialer group . then you can open /dev/cuaU0 device .
