What accessories do not work when I install Android 5.1 on my Iconia a100 /1gb ram

[AC Question]

I currently have Kingroot in place. Newbie is overstating my abilities though I am adept with windows (all) and some DOS. I am looking to get away from ICS since my tablet doesn't even like it. I want all the accessories to work, camera, wifi, bluetooth etc. If not, I will stay in my soggy Ice Cream Sandwich

Tablets and phones are not quite like computers when it comes to "drivers" and such. WELL they are similar, but generally speaking when you upgrade your tablet or phone OS, the hardware attached all should still work. NOW that being said, it may (or may not) be a good idea to upgrade the OS on this tablet. You should seek advise from others who have done it. Does the tablet perform ok on the new OS, is it still fast? Is storage ok? etc.
