Choukoumoun,
The question is related to the osmo-trx more than to UmTRX, so I'm
moving it to the Osmocom mailing list:

Hello guys.
I have a UMTRX my UHD/OPENBTS or UHD/OSMO-TRX same working fine but wen i
start osmo-trx and openbts i have this error
Could you specify where did you get sources and which exact versions
and commit numbers do you use?
Did you try to use osmo-trx with Osmocom software rather than with OpenBTS?
Osmo-trx :
linux; GNU C++ version 4.8.1; Boost_105300; UHD_003.004.000-4fa97a1

I make the VCXO configuration procedure with the GPS but no success...
The issue with "UHD: Device send timed out" have nothing to do with
the VCXO calibration. The issue is because of a issue in communication
between the host system and the UmTRX.
What is your hardware setup? Particularly:
- Do you use a switch between the UmTRX and the host system?
- Do you run it on a real hardware or in a VM?
- Is your host system powerful enough?
