The CronusMax can be used with or without a USB hub with the XBox One.
The authentication challenge and response happens once at startup so when the connection is authenticated there is no need for a continuous connection with the XBox One controller like there is with the PS4.
Remove the battery pack from the game controller to ensure it turns off after authenticating the CronusMax.
Must be in USB emulation modes 0 (Default), 1 (Dual Shock 3, 3 (XBox 360), or 4 (PS4). USB emulation modes 2 (X360CE) and 5 (Nintendo Switch), will not work.
