Thank you for the detailed information. You previously said that you were able to use the device on a laptop with USB 2.0. Do you still have this laptop available to try the device with? Or do you have another test machine? This would help us to determine if the device may need repair.

I do have the old machine.  It works on the old machine, but will occassionally have communication drops and need to be reset.  The drops are 2-3 times per day.

Hi Mark5000,

This may be issue that requires more detailed troubleshooting. I am currently out-of-office, and will have limited time to devote to this issue. On-the-phone troubleshooting may be the best way to determine the cause of the issue, or if it needs repair, so if you prefer, I would recommend to call in at 866-275-6964 and ask to speak with one of our applications engineers. Thanks for choosing NI, and have a great day!

Hi Roel F.,

May USB 4431 work with a external sampling clock?

Or do you have a similar multi card like 4431 but can work with external sampling clock?

Regards.
