Ubuntu :: Disable Default Assertion Of DTR And RTS On CP210x Device?
Mar 22, 2010
I am in the same boat as the author of this blog post:
http://eksfiles.net/2008/01/rigblast...in-ubuntu-710/
I am not able to use the workaround mentioned by the blog post author, so I was hoping to fix the actual problem.
This device uses a Silicon Labs CP2102 device for its USB-serial conversion. Is there anything I can do (up to and including rebuilding the driver with changes) to prevent RTS and DTR from being asserted by default when the device is open()'ed?
Ideally it would still be possible to assert and deassert RTS and DTR but if the only fix is to completely disable them for this device I'm okay with that.

I need to install a driver for a CP2101 USB/Serial device. I read somewhere that it's part of the kernel and was hoping I could download and automatically install it. I found this page:
/var/www/html/linux/RPM/opensuse/11.2/x86_64/lib_modules_2.6.31.5-0.1-trace_kernel_drivers_usb_serial_Tree.html
Which gave me great hope, but I have absolutely no clue what it means or what to do with it.
Anyway, I was hoping someone could tell me how to install this driver. Very new to Linux and trying to avoid compiling if possible... lost in the woods very quickly.
If compiling is the answer, then I need help there too. I downloaded the Linux driver kit from Silicon Labs web site, followed the installation instructions, ran into an error and quickly bailed. The error is:
LD/cp210x-3.0.0 M=/var/tmp/silabs/rpmbuild/BUILD/cp210x-3.0.0 modules make: *** /lib/modules/2.6.31.12-0.2-desktop/build: No such file or directory.
Which makes sense in that there isn't a /lib/modules/2.6.31.12-0.2-desktop/build directory but didn't help much with the driver install.
linux-nsxk:/usr/src/cp210x-3.0.0 # ./makerpm
++ uname -r
+ kernel_release=2.6.31.12-0.2-desktop
++ pwd

I recently made the switch from gnome to kde. After struggling for two straight days I finally have everything the way I want, and I must say that I am quite pleased with Kde. The one thing I want to do now is get my computer to start up without running printer applets and bluetooth and all that other stuff I don't need. I have had little luck finding any info on this one.

I have installed Lynx and want to use two X servers at the same time. Each server has its own ServerLayout section in xorg.cong. The first ServerLayout Section has AutoAddDevices enabled, so that new input devices are added automatically. The second ServerLayout has AutoAddDevices disabled, and one InputDecice pointing to /dev/input/mouse3. That way, this mouse is the only input decive affecting the second X instance.
Unfortunately, this mouse is also controlling the first server (due to AutoAddDecives). Can anyone tell me how to disable this? I want every input device to be added to the first server, except this mouse. In earlier versions of ubuntu, I used a hal rule to make hal ignore this mouse. So it was not added to the first server. Now that hal is not used by lynx anymore, I don't know how to do this. I have already read some things about udev and the xorg.conf.d folder.

I recently bought a new nettop and installed Ubuntu 10.10 Desktop. Unfortunately the on-board wlan is kind of crap so I bought a USB Wireless stick and since that stick has a pretty recent chipset ndis was needed to get the USB stick to work as wlan1.
The issue is I want to disable the on-board wlan (wlan0). The BIOS does not offer that option so it needs to be done in the OS I guess. My question is what is the best way of doing so? I've read something about blacklisting or editing 10-wlan.rules but I am unsure what the best place is and what to put there.
This the output of ifconfig:

11.04 64 bit I just picked up a new high-gain usb wireless adapter that I would like to use for a while in place of the built in wireless adapter in my desktop. It is detected and works just fine. My question is this: Is there any way I can disable just the built in adapter and leave the new one active (or visa versa?) I don't want to remove the built-in one as there will be occasions that I will want to use both.

I have a Kore Controller from Native Instruments [URL] using it as a sound card on Fedora 12. Its input knobs are supported by Linux, too, but they are pretty useless for me.It came out that these input knobs send mouse movements from time to time, letting my mouse pointer jumping to the upper left corner of the screen.
So I want to disable the knobs, i.e. I want X to not interpret these "knob actions" as mouse movements. What is the best way to achive this? Can I disable it somewhere in HAL configuration or do I have to modify xorg.conf? And how do I do this?Simply plugging out the Kore Controller is not an option for me because I use it as sound card.

I've always run as root on Slackware, but having done away with Ubuntu for now, all of my machines including the family desktop are running Slackware. There have been several ups and downs and the last one that I know of (for now) is the HP Device Manager. It doesn't run as root so I've never noticed that it drastically slows down printing via a shared printer. Disabled the system just sends it's requests to the samba/cups server and starts printing instantly. The HP Device Manager seems to go through an intialization step each time that takes several seconds before I can even hit the "print" button.

I am using Xubuntu 9.10 on a nettop as a X11 terminal.In order to do that, I created a custom session script that runs some commands instead of starting xfce4-session and the likes from GDM. When I boot this nettop, GDM automatically logs a dummy user in (called "test"), and runs a script that does "xhost +", and opens a small X Terminal to keep the X session alive, while some other computer sets the DISPLAY environment variable to point to <nettop>:0 and runs gnome-session.
My trouble is that after 10 minutes of idle, the screen is blanked(power saving I presume).
I tried to add "xset -dpms" and "setterm -blank 0 -powersave off" to my startup script, in vain. I want my power saving options to be configured on the remote computer, not the nettop. How could I prevent X/GDM/Whoever from blanking the screen ?

I've a custom startup script myscript.sh placed inside /etc/init.d/ directory with below lines to disable usb bluetooth device "hci0". This happens on Ubuntu Lucid.

/usr/sbin/hciconfig hci0 down &
Here is the /var/log/daemon.log
When I rebooted it worked fine disabling the bluetooth dongle. But, later on, it gets enabled! I've lost it!

I have FTPS setup on my ubuntu server 9.10 machine using vsftpd, and I want to disable the default SFTP server in openSSH. I didn't even know it was on until I accidentally connected to it. I tried searching the internet, and it seems that all I should have to do is comment out the line:
Code: Subsystem sftp /usr/lib/openssh/sftp-server restart sshd and it shouldn't work anymore.....except it does. Thinking that /etc/init.d/ssh restart may not have worked, I restarted the machine, but I can still connect over sFTP.

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

I have two sound cards active on this machine and they both work fine. However I would like to blacklist one card from being used for audio capture in KDE, because I am already using it outside of KDE for timed recording. The problem is that when I start amarok while timed recording is going on, it attempts to probe the card and this causes the recording to abort.
In Configure desktop > Multimedia, I can see the two cards. I can alter the priority but the Remove button is greyed out. So I can't remove a card from phonon.
Searching around for where phonon stores its configuration led me to ~/.config/kde.org/libphonon.conf. This certainly looks like the info I was trying to edit, but it's encoded in some way code...

I am running Fedora 12 OS on my machine. I would like to disable the USB devices for normal users so that usb-storage devices cannot be plugged in. However at the same time a mouse or a keypad may/could have a usb connection. note that root should be able to use the usb storage devices. How can the same be done on fedora 12? I would prefer not to do it via the BIOS options.

I just installed kubuntu lucid on my notebook. Every time I plug in a thumb drive, the device actions popup gives me two options - load in file manager and use gwenview importer.
I want to get rid of the gwenview importer option.
I went into System Settings->Advanced->Device Actions and found the entry for Download photos with gwenview. It can't be deleted (at least as a regular user). I tried modifying it and then deleting it, but the gwenview entry was still there afterward.

I'm trying to set rxtxSerial to work so a Java app has access to a serial port (via SiLabs CP210x driver, port /dev/ttyUSB0). When I use update-alternatives --config java, there are 3 alternatives which provide `java'. I have tried openJDK and Sun. Both fail but with completely different messages.

I use an echo indigo audio card. When I do aplay -l I see this card, and I can ouput audio through it by specifically telling mplayer to use this (alsa) device. Now I want to use this card as default for all audio. At the moment the default is pulseaudio through the built in soundcard. How can I change this? Im running Ubuntu 10.04.

I'm having here annoying "problem" with my webcamera. Everytime I want to use it as a microphone it needs to be switched manually in sound settings menu. It's not a big deal but I would really rather let it be switched automatically like plug and play or something like that.

I use a Logitech USB headset with microphone at work for phone conferencing, and for some reason whenever I restart Ubuntu (and sometimes seemingly at random times), the settings for the audio input device revert to the defaults (the internal audio hardware).I can always reset it back to the USB headset by going to the sound configuration menu (Preferences -> Sound -> Input), but if any applications that use a microphone are already running, they will need to be restarted in order to make use of the newly configured input device.

I recently bought a logitech headset which is working very nice, the thing is that I cannot make it my default device when I plug it in. I edited /etc/modprobe.d/alsa-base.conf to make snd-usb-audio the default card but it only works when the computer is turned on with the headset plugged in. A workaround is to plug it and then "alsa force-reload" but I find it very ugly plus it kills all apps using audio and leaves the volume indicator unstable.
