Hey,
there are a few posts on this topic, but none of the mentioned fixes solved my problem. Especially this thread http://forums.ni.com/t5/Academic-Hardware-Products-ELVIS/myDAQ-recognized-as-USB-flash-firmware/td-p... describes a quite similar problem, but the workarounds won't help.
My device (myDAQ) worked a few days ago. No mayor (as far as I remember) changes were made neither on the system (Windows 7 / 32bit) nor on the device itself. Teh device also works fine with other computers.
Now, it is only recognized by windows as "Unknown Device" (in the Device Manager).
Though, it doesn't matter which USB-Port on the Laptop (Lenove ThinkPad T420) I use.
In the NI MAX, the device completly doesn't occur:
As I mentioned I tried all the things mentioned in the thread from above, but with none success.
I also tried the NI Troubleshooting-Thingie:
I tried like four diffrent myDAQ-driver versions: (9.1.1f, 9.1.2, 9.5.5, 9.7.5 (perhaps I miss something here, I might lost track..))
all with the same result in the Troubleshooting-Thingie.
Here are some further system information of my computer and installed NI-Programms on the state I know the device worked once: (deinstalled LABVIEW- took quite long- and newly installed LABVIEW from CD):
I'm looking forward to any advice from you guys, because I'm quite frustrated at the moment.
Greetings!

Hey,
you don't need to worry about my problem anymore. I found some kind of solution. The USB-cable (which worked fine with the same device on another PC serveral times), seems to have some loose-connection. The 100 times I tested it with different driver versions it won't work. After switching to another USB-cable, some magic-repairish thing happens and the old USB-cable seems to work sometimes at least.
So for anyone who might have the same issue: make sure to check different USB-cables! (Could save you lots of time!)
Thanks to anyone who tried to find a solution!
Greetings

Hey loik,
I'm glad to hear you were able to get it working. Do you know if you were using the USB cable that came with the myDAQ?
I remember I use a (super cheap) 3rd party usb cable with the myDAQ and it didn't fit quite right. It connected and powered the board but the myDAQ would not enumerate in Windows. Switching to a better USB cable solved that problem for me.
