cDAQ-9172 & USB Extenders

Hello,
 
I'm trying to use a cDAQ-9172 with a USB extender (AnywhereUSB). When I connect to the extender the cDAQ-9172 never shows ready, device manager show the device as 'failed to start'. any ideas?
 
If the cDAQ-9172 did work  with USB extenders and USB over IP they would be so much more useful, probably a better solution that Fieldpoint and Compact RIO....... maybe that is the problem......... Come on NI sort this problem.

Hi Mark,

National Instruments has not yet qualified any USB extenders for use with our USB products.  Our USB products fully compliant with the USB specifications.  You might want to contact the manufacturer of your extender about this issue.

Thanks,

Sal

I already have contacted the manufacture of the equipment! They are also based in Austin, Texas..... The reply I got from them is posted below........ your call NI.

"Thanks for the great info and the screen shots.
Our engineering group actually has gotten in these NI data acquisition devices and couldn't make it work on the AnywhereUSB.
National Instruments was going to have to change something on their end to make it function correctly and they were not willing to do it.
I wish I could tell you better news."

Hello MadMark666,

CompactDAQ is a USB 2.0 device with high-speed performance. The quote below was taken from an application note on AnywhereUSB. "AnywhereUSB supports USB 1.1 devices and USB 2.0 devices at USB 1.1 speeds. USB 2.0 high
speed performance is not supported." Even if detected, my guess is that you would have limited performance with your CompactDAQ system.


The USB FAQ  suggests a few companies that provide extenders.

Good reply..... but I have tested the 9172 on a laptop that only has USB 1.1 ports and it works fine on that....... so I doubt USB port speed is an issue. When connected to the AnywhereUSB the 9172 never reports that it is ready!

Further point to note: I have also tried other USB 2.0 devices with the AnywhereUSB and thus far all have worked. (DVD writer, USB data key, scanner)

Dear MadMark666,

 

I think there may be some confusion regarding your quote and the devices in question.  I am not aware of any contact between National Instruments and AnywhereUSB (Digi).  There may have been contact in the past but NI CompactDAQ is completely new and represents new USB technology.  NI has been testing USB extender devices but, as far as I know, there has been no contact between Digi and NI regarding NI CompactDAQ.  If you
have a contact name, from either company, I would be glad to follow-up.

Thanks,

Brett Burger
NI CompactDAQ Product Manager

Followup:

I believe I have found the issue addressed in your quote.  The device was being tested by a completely different group (GPIB I believe) a while ago.  We still have not tested it with NI CompactDAQ.  I did, however, run AnywhereUSB's "device support" program and it reported cDAQ as a supported device.  Since you have discovered that the device does not work...that might be feedback that AnywhereUSB sholud know.

Thanks,
Brett
