Hi Josh,
Is the UHD driver/firmware stable? Or are the current
versions still under development?
Test case 01: Incorrect sample rate value (e.g. 100k) raises an exception,
subsequent attempts with correct values do not get a response from the USRP2.
Regarding the previous crash when passing incorrect sample rate values, I tried
to replicate the crash again, with 100k sample rate setting, and it terminates.
terminate called after throwing an instance of 'std::runtime_error'

However, after you set it back to a valid value of say 100M, it still doesn't
work, requiring a full reboot of the USRP2.
Perhaps this was because of an unhandled exception?
Test case 02: Setting the correct sample rate (e.g. 25M) works once, after that
it doesn't work.

switches to 25Msps.

The hardware does not support the requested sample rate:
Target sample rate: 100.000000 MSps
Actual sample rate: 25.000000 MSps

We're marking it DONE.
