 ## Additional tidbits
-    
-+ Change range:

-Write a value between 0 and 1080 to
-`/sys/bus/hid/devices/XXXX:044F:B66E.XXX/range`
 
-+ Change autocenter and gain:
++ T300 RS has an advanced F1 mode that can be activated with an F1 attachment when in PS3 mode. The base wheel will also work in PS4 mode,
+ but it's less tested and if you encounter issues with this mode, please feel free to open up an issue about it.
+ 
++ T248 isn't as extensively tested as T300 RS, please see issues and open new ones if you encounter problems.
+  There is currently no support for the built-in screen.
 
-Use the default evdev ways, i.e. https://www.kernel.org/doc/html/v5.1/input/ff.html

-+ Currently there is support for this driver in oversteer(https://github.com/berarma/oversteer), and ffbwrap(https://github.com/berarma/ffbtools) should work just fine.

-There have been reports that some games work better with a different timer period (see [#11](https://github.com/Kimplul/hid-tmff2/issues/11) and [#10](https://github.com/Kimplul/hid-tmff2/issues/10)). To change the timer period, create `/etc/modprobe.d/hid-tmt300rs.conf` and add `options hid-tmt300rs timer_msecs=NUMBER` into it. The default timer period is 8, but numbers as low as 2 should work alright.
