I have been trying to get an EVDO modem to work with Centos 5. I can make it dial out with wvdial only when I'm the root user. Otherwise I get this error: Cannot open /dev/ttyUSB0: Device or resource busy I added the user to the uucp group. crw-rw---- 1 root uucp 188, 0 Dec 3 02:30 /dev/ttyUSB0 crw-rw---- 1 root uucp 188, 1 Dec 3 02:30 /dev/ttyUSB1 crw-rw---- 1 root uucp 188, 2 Dec 3 02:30 /dev/ttyUSB2 crw-rw---- 1 root uucp 188, 3 Dec 3 02:30 /dev/ttyUSB3 What have I missed? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com DRY CLEANER BUSINESS FOR SALE ~ http://www.canadadrycleanerforsale.com
