Basically, I just found out inserting a SDHC card into a SD card reader (pre-SDHC) doesn't work well. When the kernel saw it, I guess it decided to disable the ports/hub that device was trying to connect to.
Code:

I know rebooting the PC will fix this, but it there a way to fix this without rebooting?
I am running Fedora 10 and Win XP SP2 on an Intel PIII machine and couple of weeks ago there was a short on the motherboard. In the result 1 out of 4 USB ports died, 2 show over current change ad 1 seems to work properly. In XP I could disable a "USB adapter" in Device Manager, which removed 3 usb's from the system, but the remaining one, equipped with the hub, works fine. Is there a way to do something like that in Fedora?
Here is the USB section from my lspci -vv:

I'm writting an app for desktop and embedded linux and I need to get information about the multiserial port, and I need to know which port is been used (by a printer, por example).The multiserial I'm using is an Altera Corporation Device 0004, and I just need to tell how many ports are there and how many is been used.
My laptop is Dell Inspiron 1440 with Dell wireless. I use broadcom-wl on Fedora 13 and it works fine. Last week I updated Fedora including the kernel from 2.6.34.6-47 to 2.6.34.6-54, Fedora can not "see" wireless anymore (there is no item related wireless on the right-click menu of the Network Manager icon, of course I can not connect to Internet via wireless)
I have squeeze installed on the old hardware DELL GX260.Howto disable completely kernel-mode-setting (KMS) on squeeze?I've tried to add /etc/default/grub:
Code: GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset" and change in /etc/modprobe.d/i915-kms.conf:
how can i disable software update's notification about kernel. It keeps showing me alot of annoyn things about the new kernel update, but i don't want to install that i already compilied 2.6.36.1 .
Kernel parameter vga=0 or vga=normal does not work as expected - First it works as expected text mode resolution is 80x25, but after some seconds the kernel, or the initramdisk does switch resolution of console again! I hate to say but it looks like OpenSuSe (again) thinks it is more clever than the user.Since rmmod radeon in runlevel 3 says "ERROR: Module radeon is in use", I do think that somehow SuSe ignores my vga=0 ... Is it the kernel or the ramdisk, I do not know where to search, since the parameter vga=0 is accepted and used in the beginning - it switch again after "doing fast boot" or 1-2 lines later..
I've got a problem with my 3G modem [Huawei E122]. It has internal storage and kernel assigns a device [/dev/sdX] to it. Because of that, every second time my machine will not boot - kernel panic - as my usb hdd gets assigned /dev/sdb instead of /dev/sda. I cannot use LABEL nor UUID in root= kernel parameter, as it is only available when using initrd, and I can't use it - I am using Debian on my router - mips architecture machine. I have to prevent this from happening, as my router has to start everyday and I have to be sure it works ok. I don't have physical access to restart it when something goes wrong. I don't use my modem internal storage, there's no SD card inserted. However kernel detects the reader and loads it. I can not prevent loading od usb drivers since my hdd is on USB as well.
i have an hp pavilion dv7 and am using f13 64bit. my laptop has a built in woofer underneath that i have never been able to get to work. after the latest kernel update today my laptop now has woofer sound. there must be some new support for my laptops audio card. the problem is that it is a little overbearing. how can i a) disable this feature b) tweak the parameters like crossover frequency or gain? edit: i checked the changelog for 2.6.34 and couldn't find any info on any new audio support features.
I have some issues concerning so called "11-minutes-mode" - RTC update"11-minutes-mode" definition In hwclock man page we can read:"Automatic Hardware Clock Synchronization By the KernelYou should be aware of another way that the Hardware Clock is kept synchronized in some systems. The Linux kernel has a mode wherein it copies the System Time to the Hardware Clock every 11 minutes. This is a good mode to use when you are using something sophisticated like ntp to keep your System Time synchronized. (ntp is a way to keep your System Time synchronized either to a time server somewhere on the network or to a radio clock hooked up to your system. See RFC 1305).
This mode (we'll call it "11 minute mode") is off until something turns it on. The ntp daemon xntpd is one thing that turns it on. You can turn it off by running anything, including hwclock --hctosys, that sets the System Time the old fashioned way. To see if it is on or off, use the command adjtimex --print and look at the value of "status". If the "64" bit of this number (expressed in binary) equal to 0, 11 minute mode is on. Otherwise, it is off. If your system runs with 11 minute mode on, don't use hwclock --adjust or hwclock --hctosys. You'll just make a mess. It is acceptable to use a hwclock --hctosys at startup time to get a reasonable System Time until your system is able to set the System Time from the external source and start 11 minute mode. Here are my questions:1 . How to check if "11-minutes-mode" is on/off ?The output of adjtimex -p looks like this:
I have Ubuntu 10.04 with Gnome. Whenever I put in a blank CD/DVD an icon on the desktop appears named "Blank CD/DVD" and a window appears asking me what I want to do with it. How do I disable the window and the icon from the desktop?
i'm using this guide videos - howto: debian linux kernel compilation, part 1 and the author says i need kernel 2.6.26 this version of kernel doesnt longer exist in kernel.org website and the only 2.6.26 i found is a patch here. should i use the patch? or download another version of kernel?
Just did a check on "shields up" and it says that ten of my ports are open. I get the same result with or without both shorewall and firestarter. I suspect it may have something to do with the mysql server packages added automatically during installation. Am I right. If so, what can be done about it? If not, has anyone any idea how to keep my ports closed?
I'm trying to setup oracle10g but, whenever I try to go to my database homepage http://127.0.0.1:8080/apex I get an "unable to connect to" error. Only reason I can think of as to why I can't connect to it is because my ports aren't open. I also recall SELinux complaining about something awhile ago, I can't seem to bring that up any more for some reason.
I'm starting to feel like a spamer or something. (I don't usually have this many computer questions, I'm a nerd, but known NOTHING about ubuntu).
All of a sudden NONE of my usb ports work? I can't get USB drives to work or an external drive. They aren't recogonized at all and the lights on them don't light up.
All i need is to see a list, window or anything that shows all of the serial (rs232) com ports that are on my Ubuntu 10.04 machine and what their associated port numbers are.
I have one com port that is on the motherboard (so obviously its com 1) and it works fine. but i also have a usb to serial (FTDI) com port that i cant figure out what the port number is...
If i've accidentally deleted the vboxusers group off my list in System-> Administration, is there a way to get it back? I really need to unlock my USB ports for my VM.
I want to test automatically if the USB ports are in use. I want to test it in a bash script
I found some information about ttyUSB0 in the /dev/
The problem is, there is usb hub between the system and the mouse/keyboard. The other USB port is in use for the Ubuntu live usb. When I open the /dev/ map virtual and pull out the usb keyboard the hidraw1 diappears, same for the keyboard. When both are out and I pull out the usb hub, nothing happens.
I need to talk to several serial ports. I was thinking of having a bunch of USB to serial cables and then plugging all of them into a USB hub, which goes to the computer. What I want to know is, will I see each serial port as a separate thing? With 1 USB to serial cable and no hub, I see /dev/ttyUSB0. With this hub, will I see /dev/ttyUSB0, /dev/ttyUSB1, etc?
I've installed Debian Lenny on a Fujitsu Amilo L7310GW, and everything works well, except for the usb ports. Anything plugged into them doesn't register at all. If I plug in my usb pendrive with the light then the light comes on for a moment and then nothing.
I started up Knoppix 6.2 from the same pendrive, and it starts to boot, right up to where you can choose the OS and options, and then a bit further but then it fails because I suppose enough of the OS has been bootstrapped to use it's own usb facilities.
I've looked at the logs, dmesg/syslog/messages/debug, and also got some output from lsusb but I can't see what could be the problem.
Have configured squid in routing server and it works fine. Able to block sites and allowed all http request to pass through squid so able to monitor http traffic. And the downloads from linux machine like wget, ftp, etc.. and from windows download manager cannot be monitored which is drawback right now. In squid is it possible to allow ports like ssh, ftp etc so that it can also be monitored? If so need some spark ideas on it.
I was wondering if there is a way to have SIP and IAX2 listen on two ports other than the standard one? This is because most ISPs are blocking these standard ports especially ISPs that is also engaged in Telecom business.
