Dell 1535 + Ubundu + Modem = disaster
Trying to activate a USB modem on my computer (see steps below) disables sound in all applications and all wireless communication and it appears may be responsible for disabling portions of other applications.
Unfortunately I must have the modem capability where I do most of my computer work and the computer has no built in modem. Support from Dell "Linux Support" has been less than useless. I am not all that advanced in Linux as yet so it does not take much jargon to confuse me. ####################### Documentation for a similar but different modem/sound/wireless "Dell problem" is found at: http://linux.dell.com/wiki/index.php..._Does_Not_Work http://linux.dell.com/wiki/index.php...Kernel_Upgrade & known issues list at bottom of: http://linux.dell.com/wiki/index.php/Ubuntu_8.04 ######################## System Specifications: Computer:........ Dell Studio 1535 laptop Modem ........... USRobotics usr5837 OS............... Ubuntu 8.04 (hardy heron) -- Kernel ....... 2.6.24-16 generic -- Gnome ........ 2.22.1 Processor 0: .... Intel Core 2 Duo CPU T5750 @ 2.00GHz Processor 1: .... Intel Core 2 Duo CPU T5750 @ 2.00GHz ########################## USRobotics Modem Information The modem which is touted as Plug and Play does not work until steps 1-4 of the troubleshooting routine provided by USRobotics are executed. Then the modem works but the Sound, wireless etc. won't work. --------- USRobotics Trouble shoot instructions -------- Open a terminal shell and log in as root. 1. Verify modem enumeration with the following command: lsusb Below is an example output. Bus 001 Device 002: ID 0baf:0303 U.S. Robotics 2. Verify the CDC ACM module as loaded with the following command: lsmod If the version of Linux kernel has the CDC ACM driver compiled into it, you should now be able to use a terminal emulator program (for example: minicom) to attach to the modem. If the kernel has the CDC ACM driver built as a module, then you may have to enable the driver with the following command: modprobe acm (used in 2.4.x kernels) modprobe cdc_acm (used in 2.6.x kernels) 3. Verify device node creation. Some distributions will automatically create a device node for the modem in /dev. Below is the device node as created in Fedora 7. crw-rw---- 1 root uucp 166, 0 2007-09-12 10:33 ttyACM0 The CDC ACM driver allows up to 32 modems. If the device node does not exist, create one using the following command: mknod /dev/ttyACM0 c 166 0 Additional device nodes can be created for additional modems as follows: mknod /dev/ttyACM1 c 166 1 mknod /dev/ttyACM2 c 166 2 mknod /dev/ttyACM3 c 166 3 4. Access the modem. Use a terminal emulator program (for example: minicom) to access the modem using the device node created above. For example, setup the serial port for minicom to use the device node /dev/ttyACM0. 5. Internet dialers. Applications such as WvDial and KPPP may require access to the modem via the /dev/modem device node. You can set up a symbolic link from /dev/modem to the ACM modem device by using the following command: ln -s /dev/ttyACM0 /dev/modem |

Also, the output of "lspci", "lspci -n", "lsusb", and "lsmod" might help. |
Hi,
I am not pleased to say this, but Dreamlinux is not a Ubuntu derivative. It consists of his own kernel, set of tools etc. It is most likely you will find confidental information in Ubuntu-section.... but you might try your modem using DL as well (do not forget to post back, then ;) ) @nno |

Hi guys. @dgoddard: As silenceGL said, we do have modem support and a PPoE Wizard to ease the process. You're welcome to try Dreamlinux. We'll help you as much as can. |
