Usrp2::usrp2::rx_samples doesn't recover from hang

GNU Radio

Hi all,
I’m doing some recovery tests in case the USRP is disconnected while
my software is using it.

What I’m observing is the fact that using an instance of usrp2::usrp2
with
decimation = 8 the calls to usrp2::usrp2::rx_samples hangs for ever even
if I correctly reconnect the device.

If I do the same disconnect/reconnect test but with decimation = 50 the
usrp2::usrp2::rx_samples hangs only while the device is disconnected.

What is puzzling me is the fact that in case of decimation = 8 I’m not
getting any error at all, so the only way I have is destroy the
usrp2::usrp2
instance (in case the rx_samples call is taking too long) and rebuild
it.

Regards
Gaetano M.

Someone have an idea on what is the correct way to detect a device
disconnection?
As stated with decimation = 8 is not that easy to discover it.
