USB-9171 installs as USB Flash Firmware Updater

I have just received a USB-9171 with 9401 module. Trying to install it on a WIndows 7 64 bit Dell Vostro laptop. Already installed is Labview 8.5.1 which has been working fine with a USB-6212 for some time. I installed the NI-DAQmx 9.6 which came with the new 9171, and the Labview 2012 Run-Time as recommended by the update manager. On plugging in the USB-6212 it loaded the driver, recognized it in MAX and operates correctly as before. But on plugging in the USB-9171, the driver loaded by Windows identifies it as USB Flash Firmware Updater. The 9171 does not show up in MAX.
How can I get the proper USB-9171 driver to load?
Thanks - Steve

This is the original poster again. Just wanted to add additional experience I had with this problem.
After getting the original 9171/9401 to be recognized as described above, I added three new 9171/9401 modules to the system several months later and encountered the original problem again. This time the original 9171/9401 would always be recognized, but the three new ones would not. I upgraded my LV from version 8.5.1 (uninstalling this version) to LV version 2012. Upgraded the DAQ from 9.6 to 9.7. There is a newer version of the MAX configuration utility that was not compatible with LV 8.5, so I needed to upgrade LV AND remove the 8.5 version to get the newer configuration utility to install.
I followed my previous procedure of wiping the configuration and then plugging in the USB modules one at a time. As WillPwr found, I needed to have patience because it didn't happen right away. Even with the configuration wiped, it would recognize the old module right away but not the new ones. This suggests that there is some record of module serial numbers retained even after a configuration reset. But eventually it did recognize them all.

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault boot volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main screen.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode.
*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Downloaded matchbook air flash firmware update will not install

downloaded mackbook air flash firmware update will not install

Awesome! I was getting really frustrated by this, but found your post and it worked. Thanks!
I wonder how apple did not come up with a warning when you start the insatllation that would tell you that it would not work with an encrypted disk. These sorts of warnings should be standard procedure. Whatever, finally the red number disappeared. Thanks lemach again!
One small addition: After turning file wault off, you need to reboot before starting the update, otherwise the decryption does not take effect.

Incomplete installation of downloaded flash player update

A required file (C:Windows\SysWOW64\Macromed\Flash\flahplayer.xpt:5) could not be written while I was installing downloaded flash player update in Windows 7 due to insufficient permissions. how do I get sufficient permissions?

Administrative permissions are necessary so that the Adobe Flash Player installer can access the Windows system registry and the following folder:
C:\WINDOWS\system32\Macromed\Flash folder for a 32-bit machine
C:\WINDOWS\SysWOW64\Macromed\Flash folder for a 64-bit machine
In Windows Vista® and Windows 7®, regardless of your permissions, you can run any application as an administrator. To run an application as an administrator, right-click the filename and select Run As Administrator. Provide the administrator ID and password when prompted.
If you need more help, contact your system administrator.

Power LED flashes, firmware updates good, and can still access the router

I have a wrt54G first version as there is no version number. About two months ago, the power led started dropping out and with a reset worked for a day or so, then, it became worse, every hour, and now only a couple of minutes. according to the help side of this site, the router will not be accessible, but it is. I upgraded to the 4.7.1.1 firmware, the problem continues, un plug and start it up. Any ideas? Could it be the 12 volt power supply going bad or over shooting the power?

yes, that is the level, verified at the router. the help side of this site says that if the led flashes like this that it would be corrupt an un accessible, but a restart of the router stops it, and it is accessible, moreover, the upgrade fails since that is the level at the router. just that it is happening about every 15 minutes (8/3) - could it be that comcast is sending packets of ??? to blow out routers? Thee state they don't like people using routers - that you are not supposed to use more than one computer with their broad band connection. Yes - serious, the e have said this twice in the last 6 months. Don't know what it could be, Saturday - Sunday it has not dropped out at all

Mac Pro SMC Firmware Update "An Unexpected Error Occurred (0)" HELP

Are you booting from RAID? even though it warns that you can't be booting from RAID, some people still run the update.
Any problem with your system?
While it only says that you need to quit any and all open programs, sometimes it helps to reboot (and boot into Safe Mode) just to begin the process.
When there was an SMC Firmware update before (last fall) some people also had trouble.
We aren't mind readers, and to say it failed doesn't give those of us reading this (and non of us are Apple tech support) a lot to go on.
+Please follow the instructions in the updater application to complete the process.+
+To update the SMC firmware on your Mac Pro:+
+Your computer’s power cord must be connected and plugged into a working power source.+
+1. Quit all other open applications.+
+2. Click Restart in the Mac Pro SMC Firmware Update window and wait for your computer to restart.+
+The SMC firmware update starts automatically. A status bar indicates the progress of the update. During the update your computer fans will run at full speed, but will return to normal once the update completes.+

Mac Pro firmware update (AUG.'07) causes fan spinning@ loud volume-

Just ran the Mac Pro firmware updater from software update and now the fan is on extremeley loudly as soon as I boot-up and *does not quiet down at all* during operation. Also, there is no power light on the front of the Mac Pro tower. I read somewhere that this was supposed to improve fan performance but is has worsened it dramatically.
I read that this firmware update is the first of its kind to not require the removal of RAID disks… but I have a RAID disk so it gets me wondering that maybe it's related…?
Mac Pro 2 X 3GHz Dual-Core running 10.9.10
Any ideas? I have tried resetting the PRAM, but nothing changed. Also, I cannot shutdown consisstenly, I have to power-down with a hard reset.
Thanks,

A. You should apply it from a non-RAID.
B. You might want to reset the SMC.
*Note: This update requires a Macintosh-formatted disk or*
*partition. If you are starting up using a RAID (Redundant Array of*
*Independent Disks) subsystem, you must connect a Macintosh-formatted*
*storage device to apply this update.*
Some USB and FireWire devices may prevent firmware updates from
installing correctly. If you are having trouble installing an update
try disconnecting non-essential devices and use only an Apple keyboard,
mouse, and display.

... and you read that it doesn't matter if the BOOT volume is a RAID?
There was/are some mis-statements out there. Booting from a RAID is not supported. Removing a RAID array was never an issue (non-boot volumes).
And me, I always avoid installing using Software Update and go to Apple Downloads.

How do we verify/validate that a Flash player update is legitimate?

Is there a method for ensuring that one down;oads and installs only legitimate Flash Player updates? For that matter, any Adobe update?

RKF wrote:
What characteristics/attributes would one look form to acquire said trust?
That's a loaded question simply because of the most obvious answer, which would be "Look for the Adobe® logo".
Problem is: there are THOUSANDS of fake sites and even more fake download "popups" with illegally used Adobe® logos in them.
You'll see legitimate "notifications" on booting up if there's an update available. The Adobe Application Manager and Adobe Updater use system date & time to notify you when an update is available. Reader and Flash Player have "scheduled" update implimentation coded into the install. These update notifications will happen when you're not online, and will appear on your desktop with a "charcoal & red" themed window, and in the case of Reader, a system tray icon as well.
ANY legitimate online Flash Player update notification will appear in lieu of Flash content in a reputable site (YouTube, CNN, etc.) and will contain a "hoverable" link that will show in your browser's status bar as "http://get.adobe.com/flashplayer/". ANY link that points anywhere other than that should not be trusted... at all, even if it has "adobe" in the url. Many fakes will add those five letters to their fake download url to fool people. They'll also use words like "WARNING" and "BEWARE" which Adobe doesn't use.
A legitimate update doesn't need to, and WON'T, "scare you into downloading it". They also offer things like "Flash Player Pro" (which doesn't exist), or a version number that hasn't been released yet. A simple right click on ANY flash content will pop up a menu and "About Flash Player" in that menu will tell you what version you're currently running.
If you see something that doesn't look right, like "13.3.1.182" available, when you have a current version that's 13.0.0.182... don't trust it. Flash Player doesn't jump that far that fast.
That's why I say discretion is best. I know several people who will click on a link just because it pops up. A few of them are clients and it's gotten to the point that I no longer feel bad about charging them $80 for 10 minutes time to clean up a mess they've made because I've warned them repeatedly NOT TO CLICK things when they don't know what they are or where they came from or where they lead. I/T managers have to lock systems down to keep employees from doing that or they'd be fixing their systems 24/7. Not so easy with personal computers, especially if kids use them.

Sonnet firmware update for OS X

Here's instructions I received from Sonnet on how to do the Sonnet firmware update for OS X (you don't need to boot in OS 9.2). Worked for me. Installed Sonnet Encore/ST 1.8Ghz on a G4 350 AGP system.
Note: you still need to have 4.2.8f1 firmware prior to the patch.
+Sonnet doesn't actually provide instructions on how to use the OS X software. Follow the directions below and I imagine you'll not have any problems.+
+MAC OS X USERS—Install Sonnet Firmware Patch+
+This section describes the installation of software required to support the Encore ZIF, Encore ST or ST Duet G4 in your computer. Please note you MUST run the Sonnet Firmware Updater before you install this upgrade card. If you do not run the updater, your computer will not operate with the processor upgrade installed.+
+1. Insert the Sonnet Installer CD into the CD-ROM drive. Double-click the Sonnet Install CD icon. When the Sonnet Install CD window appears, double-click the Mac OS X ONLY folder.+
+2. Double-click the Sonnet Firmware Updater icon; Mac OS X’s built-in Install program will launch. Follow the onscreen directions to complete the installation of the Sonnet Firmware Updater and Sonnet Firmware Remover applications to your Applications folder.+
+3. Shut down your computer.+
+4. Press and hold the programmer's button until you hear a long tone; release the button when you hear the tone. Note: programmer's button is the little tiny pinhole on the front of a Quicksilver.+
+4a. For QuickSilver 2002: While holding the programmer's button, press and hold the 'start-up' button on the front of the Mac. When the Mac starts up, release the start-up button. Continue to hold the programmer's button and when you hear a long tone, release it.+
+5. Once the startup process is complete and you have logged in (if necessary), go the Finder and select Go > Applications from the Apple menu.+
+6. Locate Sonnet Firmware Updater, and then double-click its icon to launch the application.+
+7. When the Sonnet Firmware Updater window appears, click OK.+
+8. When the Authenticate window appears, enter the Administrator password, and then click OK.+
+9. When the Wait message appears, DO NOT CLICK OK; just wait. Clicking the OK button will cause the application to quit. After the Wait message disappears, another message will appear indicating that the ROM is being patched. Do not turn the power off; this process may take several minutes.+
+10. When the message stating that the ROM has been patched appears, click OK. Shut down your computer; you may now install the Encore ZIF, Encore ST or ST Duet processor upgrade card.+
+Support Note: After updating your system’s firmware with the Sonnet firmware installer, you do not need to install the other software located in the Mac OS X ONLY folder on the Sonnet Installer CD; that software is used for other processor upgrade cards by Sonnet.+

Coming in late on this discussion, but I just discovered this post in a search for an answer to my problem getting a Sonnet Encore ST 1 GHz processor to work in my G4. No disk came with my processor, however I have downloaded the firmware patch and cache enabler from Sonnet's website.
The problem is the processor installs and after a cuda reset will boot. However after some time the computer shuts dow and on restart all I get is a blank screen. Light comes on front of the G4 and fans as if it is searching for a boot disk, but the screen is blank- no signal from the computer. Replaced the original processor and it boots normally.
I don't think the patch ever installed properly. Any thoughts on this will be greatly appreciated.

D-Link DBT-120 USB adapter needs new firmware update from Apple

I purchased a new DBT-120 USB/Bluetooth adapter for use with my iBook (Clamshell). unfortunately, it's not allowing connections to headsets as I intended.
I have a DBT-120 B1 at home which works fine with my headset but that adapter worked only after updating the firmware with Apple's updater.
unfortunately, the firmware updater will not recognise my new DBT-120 which is a C1.
Apple, please update the firmware updater for the new C1... soon!
has anyone else written a firmware updater for the DBT-120 adapters so that headsets can be used with OS X?
regards,
Gregory

I have the same problem w/ my DBT-120 v. C1
I tried installing bluetooth firmware 1.2 and Bluetooth Firmware Updater gives me the error:
"This Bluetooth device is not supported
This computer does not have an Apple Bluetooth module installed. It cannot be updated by this application."
I also tried installing version 1.2.1 but during installation that gave me the error: "This update is not needed on this computer."
I have an iMac Intel Core 1 Duo 17" that will hopefully support the headset when it finishes charging, but I would like to be able to use it on the go too.
iBook G4 14 1.2GHz, 512MB Mac OS X (10.4.8)

DAQ loading as "USB Firmware Updater" NI 6229

Need some help here, as my DAQ driver does not load. Use to work before.
See attached screen capture, loads as "USB Firmware Updater"
I've rebooted, updated to latest DAQ drivers, made sure the unit is powered, changed the USB cable and also switched the NI device locater service on and off.
Perhaps the unit is bust ?

Hi,
It sounds like it's likely a software issue; take a look at this KB:
Why Does My USB DAQ Device Show Up as USB Flash Firmware Loader in Device Manager?
http://ae.natinst.com/public.nsf/web/searchinternal/2E02F8EC5D0197928625758C005FFD8D
I suspect it's related to the NI Device Loader. Let us know if you have any luck with the instructions in the KB.

MyDAQ recognized as USB flash firmware

When I look in my Device Manager, my myDAQ is recognized as USB flash firmware, and it is also not recognized in any LabView instruments as it says "No Supported Devices." I've tried updating the driver for the USB, and I've also tried stopping and restarting the NI Device Loader in Services. Neither have worked.
What should I do?
If you ask for information please tell me the steps on how to get it.
Thank You
Emily

Firmware update broke my USB Ports!

I did the firmware update on my iPod 5G through iTunes today. As it was updating, a warning message popped up and said, "iTunes cannot find a folder. Cannot install update" (exact words).
I click OK, all of a sudden "USB Not Recognized" pops up on my screen in the task bar. My printer (connected to a different USB port) no longer is recognized, my camera, my iPod, NOTHING is recognized anymore on USB, not ANY of the 6 USB ports that are connected to my computer!
After 45 minutes on support I was told to uninstall and reinstall the iTunes/iPod updates (which won't help because my computer can't recognize the iPod!), and there was nothing else they could do.
To say the least, I am steamed! BEWARE!!! this firmware update, omg. CAN SOMEONE PLEASE OFFER SOME ADVICE OR HELP!?
I have tried:
-Uninstalling and reinstalling USB drivers
-Rebooting (of course)
-Resetting my iPod
Running:
Windows XP Pro
3.0 GHz Athlon XP 64
Thank you!
Windows XP Pro

Oh, you too...
Yes, it was a wonderful Christmas. Granny bought the kids Ipods, I had to install... and lo and behold, suddenly, no USB ports! Or so I figured out on my own... after being on hold/etc with apple for 2 1/2 hours that is (their great advice: "oh, maybe the ipods are broken. Bring them to an authorized dealer to get them checked out." Yeah, thanks. Imagine that scene.)
Anyway Kyle, I finally (and I'm not running Pro, and surely not the most but not the least, computer savvy mom around), after trying and failing to reinstall the drivers (the computer wouldn't even recognize that I had anything on the original installation cd) a million times, I caved and called the Geek Squad. I spent $99 and most of the day, had to wipe the hard drive and start over, but finally got the USB ports working again. (Gave up on my old printer tho, but was able to install a new one.) I don't know exactly how the Geek guy did it, he had to try a number of ways to reinstall the drivers. Under devices, or device manager?, where you should see them as installed, a large yellow question mark kept coming up. Whether I really needed to reformat the c drive or not to accomplish this, I don't know. Didn't care at that point.
Good luck! Happy New Year.

ThinkPad USB 3.0 Dock - Firmware update doesn't work

Hello,
My company has bought over 200 ThinkPad USB 3.0 Docks to use with HP Folios to connect dual and single monitors. Some users have experience multiple issues with this product and I am trying to determine how to resolve these issues. I first want to update the firmware that is located here: http://support.lenovo.com/en_US/guides-and-manuals/detail.page?DocID=UM014961
ThinkPad USB 3.0 Dock - Firmware Update - Lenovo Docking FW Update Tool V1.0
I have the USB 3.0 dock connected to the 3.0 USB port on the Folio. The unit I am testing seems to be working fine as I have dual monitors up, external keyboard and mouse are working.
I ran the .exe, a command window comes up, and it attempted to look for the device. The text is as shown:
1. Initialzation<> Success
Start Search HUB
!!!No device found!
Press any key to continue . . .
This has been tried on several devices and it simply does not work. Does anybody have any suggestions? I have contacted support which was a complete waste of time because they have no idea what I am talking about.

I'm going to return my dock if possible. My main problem is that I cannot view Vmware virtual machine which is required for work. 2nd I can't view photos on my dual screens, it just hangs saying "Loading...", but I can view them on my W520 LCD Display. 3rd, I can't view a downloaded video, as in an .mp4. I disabled the hardware acceleration in Firefox, so I can see streaming video.
I have a Thinkpad W520 and an X1 Carbon and both exhibit the same problems with the dock.
I tried upgrading the DisplayLink Drivers to the 7.x version and that created a slew of problems. The Dock firmware driver link in the OP doesn't work either. As mentioned it couldn't find the device. Uninstalling the drivers and reinstalling the stock one cause lots of problems with my W520. The dock would try to connect but it kept connecting and disconnecting and the cycle would continue infinitly. It wasn't until I did a system restore that I could get it working again to where I can use the dock again.
I am extremely dissapointed with this dock.

Thunderbolt Display USB ports not working after 1.2 firmware update

I installed the Thunderbolt Display Firmware Update 1.2 a few days back, and following that update, the USB ports on my display have stopped working completely. The display's Thunderbolt port and Ethernet jacks are working fine, as is the Thunderbolt/power cable connection to my MacBook Air (mid-2011, 11 inch, running OS X Yosemite 10.10.1). Any ideas on a fix?

Do an SMC and PRAM reset.
