I'm using the linux version with the latest crossover (version 11).
I had the same mouse issue identified in this forum (can only turn about 45 degrees in the game).
I saw on the wineHQ forums that some users reported better results with the following registry key set:
HKEY_CURRENT_USER\Software\Wine\DirectInput
--> MouseWarpOverride
set to 'force' (other values are enable, disable)
Link to that forum posting is here:

Does anyone know how to successfully select squad mates with just the keyboard?
Tried tabbing around but only the arrow keys and enter seem to work for squad selection.
