Not sure, the packet is either lost or stuck. My guess is lost. In which
case, the timeout cant help.
I think we can make this recover better. Can you try this diff?

If you catch the error, the future control requests/responses should
continue to work. Assuming we have lost a packet and something isnt "stuck"

Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hi,
I am trying to install USRP radio support in MATLAB (using
targetinstaller), but am unable to do so. The instructions tell me to
click "next" in order to open a web browser so that I can log in to
MathWorks and fill in a form. I do so, but I cannot click next in the
installation. Is this a bug? Is there anywhere else I can download the
USRP support package from?
Thanks

Hi Michael,
Can you verify which release you are using, and which platform (Windows, Mac,
Linux)?
Thanks,
Mike
