Logitech G29 Gaming Wheel only turns 200 degrees, not 900

With AGX Xavier board, G29 is not supported by default. After adding CONFIG_LOGIWHEELS_FF in tegra_defconfig, hid-lg4ff.c driver can work and can get data from “cat /dev/input/js0 | hexdump”.
but wheel range is 200 degrees, It Should Be 900. It can print the following log: “drivers/hid/hid-lg4ff.c: G25/G27/DFGT: setting range to 900”, but when operating the steering wheel, the steering range is only 200 degrees.

Haven’t found any problems in the kernel driver code, I think probably nvidia conflict with kernel somewhere, has anyone suggestion to 900 degrees wheel range?


May other developers help to share experiences.
