Hi，I just checked this file and it works fine here.
And my device tree is /proc/device-tree/i2c@3180000/tca9548@70 here. I think it's some hardware differences, let's ignor the 70/77 first.

pls show me the results of cmd below :

cat /etc/nv_tegra_release 
ls /proc/device-tree/i2c@3180000/tca9548@77/i2c@*
ls /sys/bus/i2c/drivers/

Regards!
