laforge has submitted this change. ( https://gerrit.osmocom.org/c/simtrace2/+/16557 )

Change subject: minor: improve trace output
......................................................................

minor: improve trace output

the USB trace now respects the global setting.
the verbosity is also decreased, not showing USB activity unless
debugging.
this also saves some space.

the reset cause is now printed.
the strings increase the bootloader size, but it already exceeded
the 16 kB limit when trace level is set to info.
