[PATCH] lib/xtrx: honouring/using the loglevel parameter

by Gwenhael Goavec-Merou

loglevel parameter is never used and let loglevel to DEBUG, with an annoying flood of message in terminal. This patch adds a call to xtrx_log_setlevel() at xtrx constructor level.

MS9120 USB VGA dongle

by Niklas Cathor

After seeing the osmo-fl2k[1] project, I've bought a USB VGA dongle, hoping it would contain a FL2000. The model I've bought looks identical (from the outside) to the black one on the picture. Unfortunately it contains a different chip: a Macrosilicon MS9120. There is not a lot of information about this chip, the manufacturer does not even publish a datasheet (I've sent them an email to ask for one, but don't have high hopes). What I've found so far is: - someone's reverse-engineering attempt of the android driver[2] - a bit of python code to read & write the chip's memory[3] The second thing is for a different chip by the same manufacturer, but it seems to work with my device as well. So, I was wondering if anyone here has already attempted to re-purpose this chip as a transmitter :) cheers, - niklas [1] https://osmocom.org/projects/osmo-fl2k/wiki [2] https://github.com/animaone/macrosilicon_reverse_engineering_journey/ [3] https://github.com/hwti/ms210x-tools
