Agilent Technologies 2000 3000 X-series Driver Example Timeout

Question

I am running the example VIs, "Acquire Waveform.vi" and "Acquire Waveform Continuously.vi," that come with the Agilent Technologies Oscilloscope driver "Agilent 2000 3000 X-series."
While my issue and attempts at dealing with it are detailed in the attatched pdf, I will outline them here. When I run either of these example VIs, the initalize the scope without error, and they succesfully run the Auto setup VI, but whenever the VI attempts to read data from the scope, it exceeds the maximum allowed time for any reasonable value I input. I get the following error:
"Error 1073807339 at VISA read in Agilent 2000 3000 X-series.lvlib: wait for acquisition complete.vi->Agilent 200300 X-series.lvlib: read wave forms (single).vi-> 2000 3000 X-series Acquire save forem.vi
Possible reasons: VISA (Hex 0xBFFF0015) Timeout expired before operation complete"
I ran the VI with several inputs for maximum time, starting from 1ms and working my way up to 1,000,000ms. I get the same error for all of these except the longest time, in which case the error reads "The connection for the given signal has been lost" (not surprising, 16 minutes is a long time)
Additionally, I have to power cycle my scope to regain control after running this VI. I assume (hope) that this is a related issue and once the VI no longer times out, the scope will function normally.
I have looked through the existing forum posts related to this and found a few that weren't close enough or weren't answered satisfactorily, however, if you think I have missed something in that regard, please feel free to tell me or post a link to that particular thread.
Any tips tricks and advice would be greatly appreciated and kudos will be given to helpful posts.

Thanks. You don't have a complete communication failure then.
I know I've used this scope and driver without any problems but the interface was probably GPIB. The USBTMC driver is supposed to emulate the GPIB protocol. I don't know if the issue is with agilent's implementation or something else. I would first make sure you have the latest driver and firmware from them. I would then try it on a Windows machine. Maybe someone else has other ideas.
