34 ##Serial Ports and USB
35 If access to the serial ports or USB (e.g. DMC-4103) is desired through gclib, the following will provide steps to join the correct access group. If using USB, be sure the controller is powered and the usb is plugged in before beginning.
36
37 ###Determine group with access
38
39 $ ls -l /dev/ttyUSB* /dev/ttyS*
40 crw-rw----. 1 root dialout 4, 64 Mar 3 16:39 /dev/ttyS0
41 crw-rw----. 1 root dialout 4, 65 Mar 3 16:39 /dev/ttyS1
42 crw-rw----. 1 root dialout 4, 66 Mar 3 16:39 /dev/ttyS2
43 crw-rw----. 1 root dialout 4, 67 Mar 3 16:39 /dev/ttyS3
44 crw-rw----. 1 root dialout 188, 0 Mar 6 11:08 /dev/ttyUSB0
45
46 In the above listing, **dialout** is the group that needs to be joined. **uucp** is another common group that may be listed.
47
48 ###Check the user's group
49
50 The default *pi* username is already a member of dialout.
51
52 $ groups
53 pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi
54
55 ###If needed, add the desired *username* to the group.
56
57 $ sudo gpasswd -a username dialout
58 [sudo] password for username:
59 Adding user username to group dialout
60
61 Log out and back in for change to take effect.
62
63 $ groups
64 username wheel dialout
65
66 gclib can now connect to serial and usb devices from user *username*.
