Odd USB behaviour

Hello fellow wireheads...
I've got a strange problem that may or may not be labview/NI related...
We have a DAQpad 4350, connected to a W98SE system via a 15' USB cable.
I know that's "long" but it is within USB specs. It's not impossible to
make it shorter, but it's not likely (unless of course that's the only
solution, I don't even know if it's -a- solution :-).
Currently we use the DAQpad to read 2 voltages and control one Digital
output line.
Every so often the DAQpad will stop responding. The "time between
failure" varies (by "eye") from 2 minutes to 60 minutes. The fix is
simple, but perplexing. Unplugging the USB connector at either end and
then reconnecting it will wake everything up "as if nothing happened".
Any ideas?
Bruce

I checked my device in powertop and it was set to "Bad", so that couldn't have been it, I guess.
But your idea made me think, and my "cute little" power script is actually causing this behaviour! I don't know what line exactly does this, but when I find out, I'll write it here. It has to be this script because when I unplug the power cord (or plug it in), the mouse stops working properly!
In case it isn't this script, I'll respond here aswell.
Thanks!

10.6.5 update - 27" iMac, Radeon 5750 odd graphics behaviours?

I updated my new iMac 27" to OS 10.6.5 today and have seen some odd graphics behaviours.
1. Dock icon for Activity Monitor becomes transparent. Running AM, hidden showing CPU history
2. White rectangle at bottom of expanding folder (list view)
3. OK Button blue/white check mark pattern when configuring VPN. GUI feels "slow"
I updated using the Software Update tool; noticed these issues and re-updated using the Combo Installer; no change.
Any ideas or suggestions? Is this just me? I have a MacBook -- no probems at all!

N Gallagher,
I had the problem earluer, but it got far worse with 10.6.5, however, I fixed it by updating my wacom tablet driver.
It wasn't the system update, but an old driver causing the problem.
Resetting PRAM, SMC and permissions and all the other standard drivel people post is nice sentiments, but it should be clear that the problem is something else because that solution hasn't solved the problem for anyone.
I have the sneaky suspicion that it's old flash and old drivers for most people.
See my original post here: http://discussions.apple.com/thread.jspa?messageID=12570261#12570261
BUT. If you have a Wacom tablet, for to their website and download the latest driver from September 10, 2010.
That's all it took for all my graphics problems to go away.

Odd software behaviour Lumia 720

I'm the proud owner of a Lumia 720 since July. I'm facing some odd software behaviour recently though. Without notice or any pattern, the current app changes to another one, sometimes four or five times while my phone vibrates like mad. It happens two, or three times a week, and there's no significant pattern but this weird "phone on speed" behaviour always ends in the Bing app. I thought rebooting was the answer but it doesn't. Does someone has any clue?

Ugura,
Thanks for your reply. I adjusted the touch sensitivity but that did not do the trick. Last night, I was already sleeping, suddenly my Lumina 720 played a song that I played before many weeks ago. That was quite odd too. With my phone connected to the charger, me asleep and there was that terrible noise from an old U2-song... And I could not stop it, nor could I lower the volume so I had to turn on my computer to find the keys to a soft reset and it was in the middle of the night.
So I waited till this morning to reset my phone to it's factory-settings. Much to my annoyance- without any external app loaded, the phone went on nuts again. This time, while vibrating taking numerous screen shots... It's like my phone is haunted. A little poltergeist in it. I need some high-tec exorcism I'm afraid.
Hope someone can help me further!

Odd USB Problem With K7N2 Delta-L

Hey all. I have a bit of a weird problem here I'm wondering if people can give some insight on. I have a K7N2 Delta-L mainboard that I've been using for two years now without the slightest problem. However, recently I've started experiencing some odd USB related problems which culminated in a big moment of panic for me yesterday. I'll start with what happened yesterday.
My system drive is 2x40GB PIDE drives running on an add-in Promise FastTrak133 controller. Yesterday, I was given 2x160GB drives from a client that I decided to upgrade my RAID with. I installed the drives and fired up my system, but had to reboot several times as the drives weren't jumpered right and not detecting on the Promise board. After I finally got the drives working, I noticed my USB had completely died. My USB keyboard and mouse didn't work and my TrueImage rescue disk (which I was going to use to restore my backup to the new RAID with) couldn't see the USB hard disk which contained the backup. I panicked about this for a while, but eventually managed to restore the keyboard and USB drive by unplugging the system, pulling the battery, waiting 15 minutes, putting the battery back and starting up. My mouse still didn't work, but once I got into Windows, it started to work after unplugging it and replugging it three times. All these devices work immediately when plugged into my laptop so I know they are OK.
Also, for the last few months leading up to yesterday, I've been having a problem with some USB devices not detecting properly when I startup. For example, the mouse will not respond until I either replug it (sometimes more than once) or on some occasions, just mash the buttons a few times at which point it kicks in. I also find that sometimes if I switch the keyset on my Zboard (which resets its USB connection), sometimes it won't get recognized as attached to the system unless I disconnect it or reboot. Both of these devices work perfectly in other systems I've tried them on and once I get them running in Windows, they don't kick out again unless the system is shut down (and they only fail to work on some boots, not all.) Every other aspect of the system works flawlessly.
I was wondering, has anyone else seen this before and is it something I can correct? Is this a sign that possibly the board is starting to die and I should look at upgrading? If I install an add-in USB card and disable the on-board USB, will I still be able to boot from USB devices? I cannot really afford a major upgrade right now, but I also can't afford to lose this system so I'll make the investment if this is a potential sign the board is failing. Thanks for reading and any help you can provide.
P.S. Here is a list of USB devices connected to my system, all of which I've tried disconnecting without fixing the problem:
Razer Copperhead Gaming Mouse (Latest Drivers & Firmware)
Ideazon Zboard (Latest Drivers)
Artec e48U+ Scanner (Latest Drivers, Powered By USB)
iMex USB 2.0 External HDD Enclosure
HP Photosmart 7600 Photo Printer (Runs Through Zboard USB Hub)

the PSU looks fine and should be capable of providing more than enough power - unless it is faulty for some reason. is it clogged up with dust? do you have another one you can test with?
does your case have its own USB port(s), if so disconnect from motherboard and see if that makes any difference
also, try going to Device Manager, uninstalling all the Host Controllers listed under Universal Serial Bus controllers, and then rebooting to reinstall the drivers
i presume you have already referred to this sticky topic: If you are having problems with USB ports, read this topic.

[Solved] Odd USB mouse behaviour on boot, needs replug to work

Hey everyone,
this post may seem similiar to the others that have been popping up about USB mice not working on boot, but I still couldn't fix my problem using those threads and I have a suspicion that mine's cause is different.
Anyway: the mouse seems frozen when X starts. After a click and 1--2 seconds, it wakes up. But if I leave it inactive for a couple of seconds, it freezes up again and requires a click to wake up again. If I replug it, it stops doing that and works properly. It feels as if drivers are getting unloaded and loaded.
I'm assuming this is a udev issue, but I don't know how to approach it. I recently switched to systemd from initscripts, but this behaviour has been the same before and now.
The outputs of lsmod and lsusb are equal when the mouse is "frozen" and when it's working.
Thanks for your attention, Matej
P. s. This doesn't happen on Ubuntu, just for comparison.

Odd SocketPermission behaviour

Hi,
I've been trying to use SocketPermissions to restrict the IP addresses from which a ServerSocket will accept a connection and am getting some wierd behaviour.
The ServerSocket will reject and close the first connection attempt from a disallowed address. Subsequent connections from the same host (using telnet) are not rejected/accepted or closed - they just 'hang there'.
The SecurityManager is also really slow at deciding whether a connection can be accepted or rejected.
Is this usual ? Or is there a way to setup SecurityManager to behave 'nicely' ?

Odd Quicklook behaviour

Running mavericks 10.9.2 have noticed a small quirk in the behaviour on one of my installs.
Selecting a group of images (mostly jpegs, sometimes tiffs) and opening quicklook. scrollling through
and quite randomly some of the images will momentarily flash up then turn blank, if you cycle through to the start and continue
sometimes those that didn't show, will show and vice versa. if you select the grid option then all will show.
all images are in either sRGB or RGB in the most part 8 bit, and all without layers or alpha channels.
there is another hard drive on my machine that has the same version of mavericks
and does not display this behaviour
I have also removed the quick look preferences from the users library and restarted but the behaviour continues.
so i was wondering if anyone has come across this and if they have any ideas as to why this might be happening
any known issues with third party apps etc.
any advice would be gratefully received
thanks in advance.

Odd return behaviour

okay, consider the following example:
public class Oops {
     public static void main(String args[]){
1:          String oops;
2:          return;
3:          System.out.println(oops);
}we get compile error at 3 saying unreachable statement .. fair enough.
now, consider this:
public class Oops {
     public static void main(String args[]){
1:          String oops;
2:          if(true) return;
3:          System.out.println(oops);
}we have modified two and now there is no errors whats-so-ever.
However, the odd behaviour hecomes obvious if we comment out line 2 where we will get "variable oops might not have been initialized." ... so it would seem that it can recognize that if(true) return; will not let the program reach 3 and hence doesn't care if oops is initialized but why don't we get a similiar error as in example one?

I don't see anything bizarre about this question. What
are you referring to?Perhaps 'bizarre' was a poor choice of words. It's just that I recall silkm posting a rather similar question before (a question about how the compiler/jvm handles thing rather than what API can one use to make foo.
No, that's not a possibility. The JLS explains exactly
why this behavior occurs:
http://java.sun.com/docs/books/jls/second_edition/html/
tatements.doc.html#236365
The reason that the second example compiles is so that
you can have code that is conditionally compiled such
as debugging statements. It's not bizarre at all, it's
entirely pragmatic and practical.Yes, of course, makes sense. (Although the possibility of a compiler optimizing it out is flashed there.)

Odd SOAMANAGER behaviour

Ok, I just managed to get my old Dell D610 replaced, but this new laptop has some odd behaviour with some Solman transactions. I can get into Solman Web Workcenter no problem, but when I try to open SOAMANAGER, I get one blank IE8 window (looks like it's supposed to be hidden), and then a few seconds later a second normal looking IE8 window opens, with a partial URL. This appears to be a problem with my local profile - I can log in to someone else's machine and it'll work, and a coworker can log into my laptop and it'll also work.
This is the URL it directs the second window to.. https://<server>.<domain>.com/sap/public/myssocntl?sap-client=100
whereas this is where it should be going. https://<server.domain>.com/sap/bc/webdynpro/sap/appl_soap_management?sap-client=100&sap-language=EN
Anyone have any ideas here? If I call my help desk they're going to be clueless on this one.. lol..
thanks.

Maybe you can rename your home folder in c:\documents and settings and login again - thereby recreating your local profile.

Odd JMS Behaviour

With our application deployed to a client, we have been experiencing some odd behaviour with JMS in Oracle 10g (OC4J 9.0.4).
The application posts multiple non-transactional messages (roughly 400-500Kb per message) to a queue, which an MDB processes correctly everywhere but the client site. At the client site, only the first message in retrieved from the queue by the MDB, as if to suggest the queue was only capable of holding one message and the other messages are not being added or are being dumped. No exceptions are being thrown, which isn't helpnig diagnose the problem.
The client site has a similar environment to our internal dev/qa environments - Red Hat AS 3.0 server, v1.4.2 jvm, same OC4J and application config.
Has anyone else experienced this kind of behaviour with JMS?

Odd gmail behaviour when using mail.app

Hello there,
Ever since upgrading to Mavericks, I've been experiencing odd behaviour when sending messages from my gmail account in mail.app. I send a message and up to ten copies of the message appear in mail.app's trash.
Does anyone know what might be the cause of this?
many thanks,
Chidi

this is a setting in gmail that interfer with mail.app
the setting is that mail.app is that when you type a mail it will auto save it while you are typing. and gmail will delete the saved onece and the mail.app will create a new all the time
duno how to turn this off, try by rebuilding the mailbox in mail.app

Odd Startup behaviour and cannot access tools- options menu

As of this morning my installation of LV8 will not display the normal startup dialog box (allowing you to open existing VIs or open a new one), but simply opens a new VI immediately. If I close this new NI then again instead of returning to the start up dialog it opens a second new (blank) VI.    Furthermore I cannot open the Tools->option menu from within a VI front panel.
I've tried repairing the LV installation and when this didn't work I went for a full remove and reinstall - still no joy!
I've also check that this is not user specific, so that when I log in as a different user on the same PC I get the same behaviour
Help - please !!
Solved!
Go to Solution.

Hi AMHurrel,
This sounds rather strange.
Did you change anything on your setup?
When you say you did a full remove and reinstall, how?
These are the steps I would follow:
The following procedure will remove the National Instrument Software:
1.     Turn off the computer and physically remove or unplug all NI hardware that you have installed on your system.
    This includes anything that is PCI-, ISA-, USB-, 1394-, or ethernet-based.
2.     Turn the computer on and go through Add/Remove Programs (START » SETTINGS » CONTROL PANEL » Add/Remove Programs)
    and remove everything NI-related. Generally, if you can remember, it is best to uninstall things in
    the reverse order in which they were installed. For example, if you installed LabVIEW, then NI-DAQ, and then the
    Internet Developers Toolkit for LabVIEW, you should uninstall the Internet Developers Toolkit first,
    then NI-DAQ, and then LabVIEW last.
3.     After everything has been removed (do not be concerned at this point if an item still shows up in the
    Add/Remove Programs list after you have removed it), close all programs and restart your computer.
4.    Go to START button of your operating system, choose RUN and type "regedit". This will open the Registry
    Editor window. Go to the Registry Menu and choose Export Registry File. Select "All" for the export range,
    and select a file name. This creates a backup of the Registry in case a mistake is made when deleting the keys.
5.     Remove the following registry components from the Windows Registry:
    HKEY_CURRENT_USER\Software\National Instruments Delete the entire tree!
    HKEY_LOCAL_MACHINE\Software\National Instruments Delete the entire tree!
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ or \ISA and delete registry entries containing any
    keys with 1093 in them.
    Do not worry if any of these trees are not listed. Continue with the remainder of the process .
    Note: You may need to modify security policies. In Windows 2000/98/95/NT, go to [regedt32] then
    Security>>Permissions. In Windows XP you can modify security options using Edit>>Permissions in the
    Registry Editor (regedit).
6.     Close regedit.
7.     Make sure that you do not have any of your own VIs or other files saved in the "C:\VXIpnp",
    "C:\Program Files\National Instruments", or "C:\WINDOWS\nidaq" folders. If you do, copy them to a
    different location. If you are concerned about keeping old virtual channels and your SCXI setup intact,
    then backup the "C:\WINDOWS\niconfig.daq" file, too. Delete all folders and files mentioned above.
    Note: If you have Windows NT/2000, replace "C:\Windows" with "C:\WINNT" in the paths listed above.
8.     Save the attached file msiBlast.zip to your desktop.
    a) Extract the file msiBlast.exe from the zip archive.
    b) Double click on the downloaded msiBlast.exe file to run the executable.
c) Choose the Show NI Installers Only selection.
d) Using (Ctrl+Left Mouse Click) select all National Instruments Software that appears in MSIBlast.
e) Press the Uninstall button. This will uninstall all of the National Instruments MSI Registry entries.
f) Optional:
The Repair option will open the National instruments Installer Program and run the repair option within the installer.
Maintenance Mode will open the Installer Program and allow the user to modify the installation. To open the installer do not enter anything in the Command Line Arg? Dialog box.
9.     Reboot your computer.
10.     You should be ready to install your software. For the cleanest possible install, first install all of your
    application development software, such as LabVIEW, Measurement Studio, etc. Do a custom install, so that you can
    install just the application WITHOUT ANY DRIVERS. Reboot your PC when requested after each install.
    Even if the installer does not tell you to reboot, it would probably be a good idea to do so anyway.
    Now install your driver software and follow the associated user manuals. Some older non Plug-n-Play hardware
    must be installed before the driver. Download the latest versions of the drivers that support your hardware
    from our Drivers and Updates software library (link below), and install them one-by-one, rebooting after each
    install.
11.     Finally, shut down and re-install your hardware. When you boot back up, it should be detected in MAX.

Odd gc behaviour?

Hi,
I'm working on a web application (Jetty, running inside JBoss 3.2.1, Redhat Linux, dual Xeon CPUs, hotspot 1.4.2_04 or sometimes 1.4.2_05) whose gc behaviour seems rather odd. I have been watching visualgc while the application is under load and have observed the following:
Using the default collector:
* I have turned off explicit GCs
* Eden is about 400M and is collected whenever it fills up. Under the load test I've been looking at this occurs about every 30 seconds This collection occurs very quickly (normally a few milliseconds). There will normally be around 2M of garbage at the end of that collection which goes straight into the old generation (maybe via s0 and s1, depending on the settings I'm using)
* The old generation is also about 400M. However, collections of the old generation happen almost every time that a collection Eden occurs, even though the old generation is very far from full. (In the test I've been looking it seems to have a "steady state" of around 100M). Collections of old take a relatively long time, normally around 1 or 2 seconds. This is an unacceptably long time for our application.
This seems very odd to me as I wouldn't expect the old generation to be collected every time Eden fills up. For our application it would be perfectly acceptable for the old generation to fill up slowly each time Eden is collected, and then for one big GC to occur once that filled up (which would once every hour or two). But re-collecting the same bit of memory in the old generation twice a minute (at a couple of times per minute) is just no good. I don't understand why the old generation is collected whenever Eden is collected.
I have tried the concurrent old-generation collector and this only made the problem worse. I also tried setting the old-generation threshold for the concurrent collector to 90% and this made no different - the old generation was still collected every time that Eden filled up.
Strangely enough, when using the parallel (high throughput) collector for Eden, the problem almost went away. I say "almost" because although no collections occured in the old generation occurred until the old generation had filled completely, the very first old generation collection (which sent it back to its "natural" 100M ") seemed to send it back to its old habits: an old generation collection for every Eden collection.
Does anybody have any idea what might be going on? Could there be something weird about our application? Am I missing some crucial GC option? Have I stumbled across a GC bug? Do I just not understand hwo this stuff all works?
Any pointers much appreciated, thanks for your time.
David

Hi,
Thanks for responding.
I started the vm with the following options:
-Dsun.net.client.defaultConnectTimeout=15000 -Dsun.net.client.defaultReadTimeout=15000 -XX:+DisableExplicitGC -XX:+UsePerfData -Xmn512m -Xms1024m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=128m -XX:MaxTenuringThreshold=0 -XX:+PrintHeapAtGC -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -XX:+PrintTenuringDistribution
(Note that I've set -XX:MaxTenuringThreshold=0 for this test so I could reproduce the problem more quickly. If I set it to something smaller then the problem still occurs, just less frequently).
I've got loads and loads of output from the GC trace (I ran a load test on it) so I'll just include an excerpt containing some of the full GCs that I am not expecting. Watching the proceedings in visualgc, I noted that most of the GCs I've included below involved a collection of the old generation (for reasons I cannot fathom). However, they are not noted as "Full GC" in the trace. Any help in understanding this much appreciated:

Files Uploaded using Mapped Drive (UNC) to SharePoint Document library Putting a copy in Recycle Bin , odd SharePoint Behaviour

Hello All,
One of my client reported a strange behaviour.
Client mapped SharePoint document library to local share(UNC, NetWork Map Drive). Opened MS Word on local machine ,saved it to the share on his local machine. The document is saved successfully to SharePoint document library. But at the same time he can
see a file with same name in Recycle bin and the size of the document in Recycle bin is <1k.
Does any one know whether it is expected behaviour, why SharePoint putting this 1k file in Recycle bin?
I tried the same thing on my Dev Environment for both SharePoint 2010 and 2013, in both environments the behaviour is same as my client experience.
I have seen in forums some other people also experiencing this odd behaviour, but no one knows why.
any info on this much appreciated.
Regards,
Andrew

Hi Andrew,
i tried in my environment for 2010 and 2013. The issue doesn't occur.
Here is what i did.
1, Create a new mapped drive(\\servername\DavWWWRoot\Shared Documents) for document library
2, New a Word doc and input some string, save in the mapped drive.
3, The doc exists in the document library, but no file in Recycle Bin.
Did i miss something?
Regards,
Tom

MSI X79A-GD45 Plus Odd USB problems...

I'm having some odd issues with my MSI X79A-GD45 Plus... The system overall works well, and other than these little nagging annoyances the machine works.
I'm looking for any other suggestions you all might have of this issue.
Every so often when I plug a device into the USB 3.0 ports the devices are not recognized. This ranges from flash drives to USB headsets. Rebooting the machine does not solve this. I have to shut down completely and cold boot to get the ports back up and running. It matters not if I use the front panel ports or the rear. All the while my keyboard and mouse which are in the rear USB 2.0 ports never fail to work.
I am going to plug the front panel into the USB 2.0 headers on the mainboard just to test and see if I get the same results, I'm thinking that should tell me weather or not the motherboard or the front panel is the culprit.
That aside any other suggestions would be very much appreciated.
One other thing and I am not sure if this is related to my issue... Most of the time when I boot the machine, the text for the POST messages are very large, like real zoomed in. If I go to the BIOS when this happens the BIOS is also way zoomed in and it is very slow/unresponsive. If I want to use the BIOS I have to restart the machine until I get the text normal looking, even then the BIOS seems kind of slow compared to my last MSI board (990FXA-GD80) which had this same type of click BIOS. This phenomena happened both with the BIOS the board came with and with the updated BIOS I installed to fix a sound issue.
Again not sure if that has anything to do with the USB thing but I wanted to put that here just in case the issues are related.

Try updating the NEC firmware:
