USB-6509 Stops being recognized by Windows 7 device manager.

I am currently using a USB-6509 under Windows 7.
On a freshly formatted machine I have no trouble setting up the device using the National Insturments Measurement & Automation Software version 9.4.
Some windows updates were pushed to the computer that my USB-6509 was connected to, causing the computer to reboot in the middle of use. When the machine came back up the USB device couldn't be found by the Measurement & Automation Software, nor by Windows Device Manager. I did a complete uninstall of the software and reinstalled, this did not fix the issue. I uninstalled 9.4 and installed 9.5 and this too has not resolved the issue.
Inside device manager windows will show "Static Digital Firmware Loader" under "Data Acquistion Devices". But there is nothing installed pointing to the USB-6509.
The green light on the back has yet to come back on. I would prefer not to reformat if at all possible. Any suggestions?

I was having this exact issue. "NI Device Loader" was running on the machine, but stopping and restarting this service by itself was what finally caused the device to start working again after lots of rebooting and other troubleshooting steps. Thanks for the tip.

Why is my iPod Touch not being recognized in iTunes, Device Manager, or my entire computer?

I have had my iPod Touch since christmas and it is now June. The version is 4.1 and it's the one with the camera. My previous cord worked fine and I never had any problems with iTunes or my iPod before. I lost my cord for about a month (actually I have no clue how long) and my dad picked one up for me yesterday. It cam in a BELKIN package with the USB cord that plugs into a wall charger or car charger. So, I needed to upload my music and when I plugged my iPod in, I went to go sync the music, and I noticed the was no "Device" column in iTunes. So, I went into "My Computer" and didn't find it in (E:) where it always used to be. Then I searched the WHOLE computer and I couldn't find it anywhere. Then I searched for help online. Everything kept telling me to go to device manager and reinstall the device and blah blah blah. BUT IT'S NOT EVEN IN THE DEVICE MANAGER!! I couldn't find it anywhere in there! So like, is my iPod completely erased from my computer forever??? I tried restarting my iPod, my computer, and I made sure my iTunes was the lastest version. I also tried 3 different USB ports and none of them worked!      SO NOW WHAT!!?? Should I try a different USB cord?? Please help!!!
          Sincerely,
   Desparate Girl Who Loves Her iPod Dearly                      P.S. I have Windows XP.

You should get a genuine USB cord from Apple, to make sure your iPod 4G is supported correctly.
In addition to that see if Apple Mobile Device Service is still installed and active on your computer. More info in this article: http://support.apple.com/kb/TS1538

Any ideas?

Verbatim USB Flash Drive Stops Being Recognized

All of a sudden the other day, my Verbatim USB flash drive just stopped being recognized... it had been mounted, a TM backup made to it when all of a sudden I got an error stating that it had been improperly removed... it was like I had yanked it from the USB port...
I tried unplugging it, reconnecting, rebooting, moving it to another computer... no luck... it doesn't even show up in Disk Utility
Verbatim has agreed to replace it under warranty but I'm wondering if there's anyway that I can mount it again to retrieve the TM backups...
Any thoughts?
Many thanks!
-Justin

My Verbatim 32G flash drive appears on the left, but it will not allow me to repair it, mount, or eject it. It will not show up in Computer like it normally does. I have tried restarting it, turning it off, and doing Command+Option+r+p, which did not work. I believe I caused this problem by accidenlty ejecting the flash drive before safely removing it. How could I make it appear on the Computer again?

Do I need to reinstall Lion because my iPhone stopped being recognized by...

Do I REALLY need to reinstall Lion because my iPhone stopped being recognized by Image Capture, Aperture and iPhoto but still shows up in iTunes?
I was on the phone with Apple Support with 5 different Advisors for more than 3 hrs today and we were not able to resolve the problem (yet). Although the problem is frustrating, it's always kind of a pleasure chatting with the Advisors. (I said kinda)
Approx 2 weeks ago, iPhoto, Aperture and Image Capture all stopped recognizing my iPhone. Oddly, iTunes has no problem recognizing the iPhone. Here are just a few of the things we tried but didn't get the apps to see the iPhone again:
- Removed and deleted all photos on camera roll using a windows machine
- Removed all other photos synced between my iMac and iPhone
- Made sure an image existed on the camera roll
- Recorded some video on iPhone and then tried to get iMovie to recognize device
- Restored (gulp) the device followed by a restore from back-up
- Restored again (double gulp) but this time to factory settings and kept the device as a "new iPhone"
- Logged on as different users
and on and on.
Also, after noting that my machine refused to send a systems report to my Sr Advisor (Jimmy) at Apple, he suggests we re-install Lion (ack). But when we went to access the Recovery Partition we realized it wasn't there.
No recovery partition?
Not sending system reports to Apple?
Several Apps not seeing iPhone while others are recognizing the device?
So now I wait for Lion to arrive on one of those nifty Apple thumb drives for me to try re-installing ;-(
The following screen grab shows my iPhone in iTunes but not recognized by Image Capture. URGH!

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.

My iPad stopped being recognised by Windows 7

My iPad 1 recently stopped being recognised by Windows 7. It makes the bing-bong noise when I plug it in and the 'Not charging' notice comes up, but the 'Apple USB device' no longer appears in Device Manager and iTunes (latest version) does not recognise it, so I can't sync or backup. It used to work perfectly, but stopped working about a week ago.
My details:
iPad 1 64GB 3G
Windows 7 Ultimate 32-bit
iTunes 10.2.2
Things I've tried:
Different USB ports
Different cables
Hard-restarting the iPad and the PC
Does anyone have any ideas?

Hello,
I followed all the steps in that article and it still doesn't recognise my iPad.
The symptoms are that when I plug the iPad into a USB port, Windows does not find it at all. Usually you get the Windows 'bing-bong' sound effect and Device Manager refreshes itself as it finds the device, then you'd expect to see 'Apple Mobile Device USB Driver' in the list under Universal Serial Bus Controllers (I think, from memory).
However, Windows detects nothing at all. What's even stranger is that the iPad is clearly receiving some power as I get the iPad 'plugged-in' sound effect and the battery status changes to 'Not charging' as I would expect.
So I've removed iTunes and all associated software, restarted, reinstalled from a fresh copy from apple.com...now I'm out of ideas. I've tried two USB cables and four different USB ports.
Thanks,
Steve

Ipod video stopped being recognized by computer or itunes

5th Gen 80GB is not being recognized by Windows/iTunes

Alright guys, here's my situation. My iPod has always worked fine. Today I plugged it in like I do every other day. When I plugged it in iTunes did not recognize it and then I got a Windows message that said "One of the USB devices attached to this computer has malfunctioned and Windows cannot recognize it." I thought this was strange because NOTHING about my iPod/iTunes had changed whatsoever. Next, I was prompted to update to the latest version of iTunes so I thought, "Oh dummy, that was the problem, you had an old version of iTunes." Wrong. I updated iTunes and STILL no recognizing of my black beauty. Next I turned to the Apple website to see what it said. I tried all of the options except "restore" because I refuse to lose my collection on my iPod. I have also tried using a different USB port, but that wasn't the problem. Reminder: the iPod is not recognized under the Device manager. So now I turn to my brothers here to help me solve my problem.

Try a different cable and if that fails, see if it is recognised in another computer, if youre ipod is still within warranty send it back to apple, it may be the dock connector.
Good luck and welcome to the boards

EA6500 stopped being recognized by wireless printer

Last week, my EA6500 stopped being recognized by my wireless Canon printer. The laptops and ipad can still see the router. How do I fix this? I have tried router power off, and, complete reconfigure as if new. Has not fixed the wireless printer issue. THe printer can see other networks
Also, one suggestion was to do a 'reconnection' to the printer by first pressing a wps button. Does the EA6500 have this button?

Hi jjohnsen8!
In my case, what I did was disable the Simple Tap feature on the router. It's also running on 2.4 GHz so it may have interferred to the network. On the Linksys Smart WiFi, click on Wireless >> Simple Tap >> the select OFF.

Do you have windows mobile device center installed(WMDC)? If not download it from here http://www.microsoft.com/windowsmobile/en-us/downloads/microsoft/device-center-download.mspx
Be sure you download the correct version for your PC. If you have 32bit OS or 64bit OS. To find this out, right click on Computer under start and select properties. Near the middle it should say 32bit or 64bit. If you know you have the correct software. Open up the control panel and go to sync settings. Right click on the partnership you have setup and select delete. On your device go to Start-->Programs-->Activesync-->Menu-->Options tap on Windows PC and select Delete. Then once both are done resetup your partnership. But this time uncheck everything. Then once it is done syncing. Go to Mobile device settings and change content sync settings and select Contact. Click save and let it sync. Do the same for calendar, tasks, and notes but leave the last item checked. So when Contacts are done syncing you go and check Calendar and leave Contacts

IPhone 4S stopped being recognized by my PC. I've tried the other Apple Forum guide, nada.

Hi All,
I've read the other guides and the Apple 101 regarding PC not recognizing the iphone.
It's missing from Device Manager. Uninstalling USB drivers does not help. No other phone works, my phone works on other PC's though.
Syn
I ejected the phone - downloaded some songs on PC itune, updated my library and then tried to plug my phone back in (USB). Nada. It does not show up as a device in explorer.
I've tried it on another computer and it works fine. Nothing is wrong with the chords. Other devices are not being recognized on my PC.
I've tried this forum's solutions: http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/iphone-4s-is -not-recognized-and-no-driver/a8232b2f-5f88-4820-b81e-5d7f9c9691f5 --- it was no help
I've tried this link: http://support.apple.com/kb/ts1538 -- nothing worked.
Chords are in working order . I've tested on other computers.
As you can see - drivers missing and not displaying as a device. Software installed numerous times - I even deleted the library files and related in other folders for other software. I've pushed autoplay back to default, and reset all it's settings for recognized devices.
Please help!

IPod Classic 5th Gen (30 GB) not being recognized by Windows 7 Vista Netbook.

My iPod isn't being recognized I tried everything . Reinstalling Itunes. Resetting Ipod. Putting it in Disk mode. everything. I plugged it up to my school's mac desktop and it syncs and everything. On my Windows it doesn't even show up as mass storage device or anything. It's annoying. I just want to listen to music.
Is there a driver or something?
My friend said Registry fix, but i doubt it.
When I try to update driver, it says the most recent one has been updated.
This *****.
Please help

When you plug in the iPod does it even appear in Device Manager? See this article for more details.
http://support.apple.com/kb/TS1496
Otherwise, I have a feeling that the USB ports on the Netbook don't output enough power to allow the iPod to fully communiate properly with the Windows Vista O/S.

Iphone 5 is on recovery mode and USB is not being recognized by PC

Hello! I promise you this will be very usefull! just read!!
So I had this same problem and I tried a lot of things including hitting on the on/off button along with the middle button at the same time but it did not work!!!! here's what I tried- all of what I'm gonna mention now in PART A didn't work because they were working perfectly on my pc so I didn't have to touch anything related to them, so if you have everything perfectly installed/updated and so on then please move to part B down there
I have found some very good info here: http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/usb-device-n ot-recognized-in-windows-7/8106a712-a13e-4ca5-b82e-c3961cc254b1?page=8
And I want to share it with you guys in case you got stuck with this issue of having an iphone 5 on recovery mode and not being able to fix the problem when the usb of iphone is not recognized by your PC.
PART: A
First of all, check if all problems do not exist, like:
1- Newest version of itunes
2-all necessary updates are done on your windows. ( if operating system is up to date ) just click on start and write updates and it will show alone click on it and check if you have necessary updates to make.
3-check your security software.
4- update security software.
5-restart your computer.
If all of the mentioned above are working perfectly and the problem STILL persists then move to PART B : ( This has worked and because I was so much excited that it worked after trying and checking for answers for 2 days I thought about sharing it so you won't suffer as I did because I don't want anyone to experience that)
Here's what to do:
Click the START menu , on the search bar:
write: >> Device manager <<
*if you cannot find it through the start menu then go to control panel: Click on hardware and sound bar - after opening this you'll find a title with " Devices and Printers" under this title you'd find 5 options to do here I'll list them in order:
DEVICES AND PRINTERS:
(( Add a device | Add a Printer | Add a bluetooth device | Mouse | Device Manager ))
Note that I have windows 7 and this is what worked for me, if you have other windows and if you cannot reach your device manager button then please do check that online to get the accurate details about finding the device manager, it's the most important step here that's why, for example write on google: how to open device manager on windows 8 or windows 7 or MAC etc..
Okay, so now you have the device manager opened ( before you do anything now unplug your iphone's usb from the PC) in Device manager's list of contents you will find " Universal Serial Bus Controllers " click on it to expand it,
after you expand it you will see many options related to USB's and stuff, find the one related to your iphone it will say " Apple mobile device USB driver ( recovery mode) click on it - click properties >> Uninstall -
after you uninstall this apple mobile device USB driver, open itunes ( must be in the very recent version) then plug the usb of your iphone to PC, you'll suddenly see the little bar down on the left side of the screen saying " installing new usb driver" something like that, wait till it's successfully installed then itunes will inform you about your device connection with it and how to deal with it through restoring it, you just click on restore wait few minutes and then smile your phone is back to live !!
I hope it works with you as it has worked with me!!
Best regards,
Rana Km.

Also if you have an experience to share then do share it as well please.
