using 2 usb-9481 devices gives error for one of them

[Andrew Leneway]

I have 2 usb9481 devices in my system. i can get them both to work indepenantly, however when they are both hooked up the most recent one that's hooked up works where as the other one gives the error msg...

"Error -50405 occurred at V3P3 - DAQ Assistant

Possible Reason(s):

No transfer is in progress because the transfer was aborted by the client. The operation could not be completed as specified."

Any help on this situation would be great.

Hi there

can you please post us some code? How are the devices connected to the system? Have you tried to use another USB - port?
