Windows 7 doesn't recognize usb 6221

Hi,
I had an application (plus the entire package with Runtime and DAQmx) in Labview which is deployed on several PC. Until now it worked just fine on PCs with WinXP.
Now I have to install the same application on a PC with Win7. The problem is the LabView cannot recognize the USB6221 board.
In Windows Device Manager the board is there, but LabView sees nothing. Also, if I check in Measurement and Automation I cannot see the board there. I installed and reinstalled the entire software but no results.
Does anzbody had the same experience or could anybody give me some hints??
Thanks,
Paul

Dear Pauline,
There are some factors you need to
consider while porting to windows 7 platform. As far as i know, only
labview 2009 software is fully compatiable with windows 7.
Meaning
to dispatch to windows 7, you will need the following.
i)
Labview runtime engine (Labview 2009)
ii) Any drivers
(DAQ, DAQmx ) compatiable with windows 7.
iii) exe created
by labview 2009.
Last time, i also face similar problems. I build
the exe in windows Xp platform (Labview 8.6) and i can dispatch to
windows Xp and Vista platform. However when i port the exe to windows 7
platform, i also cant get it to work well after many tries.
Finally,
i just upgrade to Labview 2009 and compile the exe under windows 7
platform. Dispatch this exe together with the lastest drivers (windows 7
drivers) and my exe works well for all platforms (XP, Vista and windows
7) now.
This may be something you like to try out.

Windows PC doesn't recognize iPod

I have bought my iPod (20GB, click wheel) one year ago with an extended warranty of 3 years. It was working well all the time. But now my Windows computer doesn't recognize the iPod any more although I haven't changed anything on it.
The battery can still be charged using the docking station. But as soon as I plug in the iPod on my laptop USB port the iPod freezes. The only message on my laptop screen says that the external hardware can not be recognized.
The USB port is working properly.
I have also tried to install the iPod update and to reset the iPod. Nothing is working. I guess I can't restore the iPod since it's not even recognized.
Thanks, Annemarie

I thought I was alone with this problem. I recently went traveling last weekend, and began to think the X-Ray machines killed my iPod!
Whenever I connect my iPod to any computer using the USB connection, Windows will not mount it as a removable drive. The cable is good, because the iPod is being charged but Windows will not recognize it.
I have tried all the different USB ports, even on several different computers. Including my work, laptop, and my desktop. Windows will not recognize my iPod using the USB connection.
I'm in the process of restoring my desktop computer after a hard-drive failure (lucky me all my vital data were on a separate drive), so my desktop has a nice clean install of Windows.
My desktop has a firewire port, so I tried connecting to that port and Ta-Da, Windows recognized and mounted my iPod as a removable drive! Unfortunately my laptop nor my work computers do not have firewire ports.
Can anyone explain why the USB function suddenly stopped working? Does this mean I need to restore and loose all my music from my iPod? I do not let iTunes manage my music, I do that all myself. I can put my music back onto the device but it will be time consuming. If anyone knows the answer to this USB problem, perhaps you can reply to this thread or contact me.
Thanks,

WINDOWS XP DOESN'T RECOGNISE USB FOR IPOD NANO 2GB

HELP!
We recently bought 2 i pod nanos in Florida, returned to the UK where we set about connecting them to our pc - pc doesn't even recognise the USB cable, but does recognise a friend's nano which we have tried. We didn't get a cd with the ipods, can someone please give us some advice? apple support website useless.
Thanks in advance

First of all, try another port on your computer. Some ports are not connected direct to the motherboard and do not recognize the iPod as well as those that are. Reset the iPod each time you connect it to another port.
Then try with the iPod in forced disk mode.

Mac Pro doesn't recognize USB 3.0 PCI express card

Mac Pro doesn't recognize USB 3.0 PCI express card. Does it need specific drivers?

I did a little searching for that card. The more I looked at it the more I felt that, yes, it needs a driver, and no, one doesn't exist for the Mac. So it looks like that is a card only supported for PC's. But to be sure, if I were in your place at this point, I would contact MSI directly.

My computer using Windows 8 doesn't recognize my Canon Rebel. How do I fix this?

My computer using Windows 8 doesn't recognize my Canon Rebel. How do I fix this?

Hi MWCRILLY,
To connect your camera to a Windows Vista or Windows 7 computer or Windows 8 computer, you'll need to change your camera's "Communication" mode.
To set your camera up for this, please do the following:
With the camera disconnected from the computer, turn the camera on. Press the "Menu" button. Now select the [Wrench, Hammer, 2] tab. Scroll down to "Communication" and press the "Set" button.
Select the [Print/PTP] and press "Set". This process is more completely described (and illustrated too!) on page 121 of your Digital Rebel XT instruction manual.
Now connect your camera to your computer and turn the camera on. Your computer should now recognize and have access to your Digital Rebel XT.
Unfortunately, Canon software cannot communicate with the Rebel XT when operating in this mode.
You may download your pictures using Windows Photo Gallery. If you haven't already done so, you may retrieve and install this program from Microsoft's download.live.com.

My Windows PC doesn't recognize my iPod as an iPod

Hi,
I recently bought an iPod Touch 5 gen and when I plug it to my computer it doesn't recognize it as an iPod but as a non specified device. What's the matter? iTunes doesn't start up when i plug the iPod in, even if I check the box that says it. I must sync the iPod manually, and last.fm software doesn't recognize it as an iPod as well. I tried to plug my iPod to another PC an it works just fine. I cleaned the system registry but it didn't worked. I use Windows 8.1 and the latest version of iTunes.The strange thing is that even when the iPod isn't plugged in, iTunes says that it is plugged in. I really don't know what to do.

Windows Vista doesn't recognize Mac Pro RAM

I have installed Windows Vista Business on my Mac Pro using Boot Camp, and have found some anomalies that seem strange. It is basically working well (for Windows....).
1. I installed this on a 500Gb HD on my Mac Pro. This machine is a fully configured box doing video editing, with extensive AV files. It has all four drive bays filled, 3 of them with 1Tb drives, the thrid with a single 500Gb drive. I was a bit surprised to find that Boot Camp won't allow partitioning of its OSX installed boot HD beyond a Mac Partition and the Boot Camp paritition, or a secondary entire HD dedicated to Windows. This is not very practical with these large drives, since even though HD storage is fairly cheap, I don't want to give Microsoft more than maybe 100gb on a drive. All of the other HDs are partitioned for multiple parititions, which I need to preserve. The OSX boot drive has 3 OSX partitions already installed. Any ideas on how to do this better? Yes, I know I can use Parallels or VMWare, and do, but find that native Boot Camp Windows is better.
2. Windows Vista is running on a dedicated HD in Boot Camp on this machine (to all appearances running fine), but doesn't recognize more than 2Gb of RAM on my machine which is configured with 10Gb of RAM which is recognized appropriately in OSX. What am I missing?
I would appreciate any help on a partitioning scheme that works to support multiple partitions on these large drives, and a reason that only 2Gb out of 10Gb of RAM is recognized by Windows Vista Business in Boot Camp.
Thanks!!!

Thanks for your response.
I am running in Boot Camp, which runs in native mode without emulation. The advantage is that if you are going to run Windows, which is my goal, it doesn't have the overhead of OSX. Indeed, most Mac machines are among the fastest Windows machines available for equivalent hardware when running Windows in native mode. There are a few more arcane advantages to running natively, particularly in terms of connecting to external devices. There is no background RAM overhead when run natively.
Thanks....

Trying to dual boot Windows 7, Mac Pro 3 (2008) doesn't recognize USB boot drive

My system has no optical drive either. I've managed to set up the boot drive in VMWare fusion, and I've confirmed that the boot drive is correctly formatted, because it shows up on my MBP. I've tried blessing this hard drive, I've tried boot camping my way in, but the Mac Pro 2008 model seems adamant about only going via disk. Any super user commands to get my usb thumb drive recognized at option-restart time?

You will need to use Winclone to move images from one Mac to a different Mac if there are any hardware differences. It is a commercial tool.
Please see https://twocanoes.zendesk.com/hc/en-us/articles/202814148-Migrating-a-Boot-Camp- Partition-with-Winclone-4
It requires a Sysprep on the source first to remove any HW-specific parts and make it a proper image to move it to a different HW platform. Once you have this migrated, you will need to reactivate Windows and install the appropriate Windows drivers which will support your MP-specific HW.

Windows 7 doesn't release USB stick - can't safely remove USB stick

Sometimes when I'm trying to safely remove an USB stick formatted with NTFS from any Windows 7 installation, Windows 7 refuses to release the USB device.
This occurs on host machines as well as on VM guest machines. When I'm attaching the USB stick to a virtual machine (VMware Workstation) and when this effect occurs in there I can see from Workstation's device manager that the USB stick is getting accessed
once every (approx.) five seconds. The USB stick shortly flashes up accordingly then, so there is indeed some access to the USB stick.
Now, this doesn't happen all the time. This effect only occurs, say once or twice a week.
Waiting for 5 to 10 Minutes, the low-frequent regular short flashing finally stops and I can safely remove my USB stick then.
Well, what I want to know: Which Windows service is sometimes accessing my USB stick in this manner?
This happens on several machines, some of them having almost no software installed.
When exploring the file handles with SysInternals Process Explorer, there's only a Windows Explorer handle attached to the USB device.
I suspect it might either be Windows Defender (having Search Removable Devices enabled), Windows Search or Windows Defragment. But this is only a guess.
Can anyone please enlighten me on which service is capturing my USB device for such a long time, keeping me from safely removing the USB device?

4.Allow execution of PowerShell scripts:
◦Open the Start screen, type "powershell", right click on the Windows PowerShell result, and select Run as administrator.
◦Type or paste the following command:
Set-ExecutionPolicy RemoteSigned -Force
4.Close the PowerShell window
5.Open a PowerShell window (you don't need to Run as administrator) and run the following commands. Adjust the path if you installed the kit to a different location:
cd "C:\Program Files (x86)\Windows Kits\8.0\Tools\x86\Network Monitor Parsers\usb"
..\NplAutoProfile.ps1
Now you're set up! You can now launch Netmon and open an .etl trace by selecting File -> Open -> Capture.

I'm trying to send a jpeg from the Imac to a windows PC. The windows PC doesn't recognize it as a "file" with the paper clip. Why? The same file from my iPhone makes it fine. It is sent as "windows friendly" attachment.

This is very frustrating. I use Aperture and share pictures all the time. The thought that some people can't download jpeg images I send them is very troubling. As a test, I'm sending them to my work PC which is in front of me. The file arrives and can be seen in the email, but it does not show up as an attachment and therefore you can't save it. There's no paper clip in the file when it arrives. When it's sent, it shows the number of files being sent and the size. And like I said, if I send a file from my Iphone it arrives as a jpeg file fine on my work pc. I have checked my default settings and they are set to "windows friendly attachments". I'm not sure what "at the bottom of the email" means really. This seems to happen wether I originate the request form Aperture or from the email program on my Imac. Help!!

No, that doesn't work for me. And things seem to be inconsistent. Where it lets you vary the file size (small/medium/large/actual) when large and actual are the same, it doesn't send the actual jpeg file for windows to open. When large and actual size files are different when you toggle between the two, the file seems to go through to my windows pc ok. When I tried this through preview, that's when I noticed this difference, not through just email or Aperture yet. Help!
