as far as i know you can use a usb hub just fine- i use it on my iphone. usb hub allows me to use a keyboard and a very limited weird use of a mouse (apple still doesnt allow full mouse control on iphones but allows it on ipads) shadow's last work around for mouse use on iphones was patched out in late 2023. -(i have never used a ipad for shadow/because i dont have one/ but as far as i know it should work. You might have to maybe enable some specific ipad settings separate from shadow app)-

you can do some searches through the search bar of the help and question tab up top. and some searches on shadow FB and reddit- that may help with your decision
