a quick closer look into v.in.osm, it's just a wrapper around v.in.ogr

tested:

v.in.ogr input=D:\dl\osm\saarland-latest.osm.pbf layer=lines
output=roadsvingor where=highway is not null
Check if OGR layer <lines> contains polygons...
WARNING: Width for column osm_id set to 255 (was not specified by OGR), some
strings may be truncated!

just imported all lines where there is an entry in the "highway" column for
me.

it's what in
https://trac.osgeo.org/grass/browser/grass-addons/grass7/vector/v.in.osm/v.in.osm.py#L117

117	            grass.run_command('v.in.ogr',
118	                             quiet=True,
119	                             input=options['input'],
120	                             output=self.getNewTmp('ogr'),
121	                             layer=options['table'],
122	                             where=options['where'],
123	                             type=options['type'],
124	                             flags=flags['o']
125	                            )

if you do ogrinfo -al -so saarland-latest.osm.pbf, you see the structure of
the osm.pbf file:

e.g.

Layer name: lines
Geometry: Line String
Feature Count: -1
Layer SRS WKT:

    DATUM["WGS_1984",
        SPHEROID["WGS 84",6378137,298.257223563,
