Rather than changing the device permissions (which you have to do every 
time you boot or unplug/plug the usb serial device),
you should add yourself to the dialout group:

sudo usermod -G dialout <your_username>

where <your_username> should be replaced with your username on the 
system. The above will execute as root, so you need to have sudo 
permissions. There is probably some GUI based tool for this but command 
line is simpler ;-) After doing this, you will need to logout and login 
again. You can verify that you have the correct group privs with the id 
command, for example, for me it says:

uid=500(eloranta) gid=500(eloranta) 
groups=500(eloranta),18(dialout),39(video),489(pulse-access),490(pulse),493(jackuser)

where 18(dialout) is the important part.

As for curl, I think the utility program should check for its existence 
during startup and appropriately tell the user to install it before 
proceeding.
