Subject: Permissions and libftdi
I am currently experimenting using libftdi on Ubuntu. I compiled the
danny@ubuntu-desktop:~$ gcc simple.c /usr/lib/libftdi.so -o simple
When I tried to run it, I got the following error:
unable to open ftdi device: -8 (inappropriate permissions on devic
When the example is run as root, it works fine.
danny@ubuntu-desktop:~$ sudo ./simple
FTDI chipid: 7EEE7FC5
Is it absolutely necessary to run the program as root? Or is it possible
to change the permissions of a user on the device? If so, which device?
I couldn't found anything on this in the documentation.
