    Found a good looking branch on the ground and when I took a look at it I saw it had a clean cut but had little white bugs on it and a tunnel through the branch.Any idea what they are and how to kill them?

    I am not sure on the tree type that may help maybe someone from your area will chime in or @Trees Too

    I think I see white barnacles on the other branches and a few leaves if so that's scale

    A tunnel sounds like a borer usually named after the tree or bush they're inThumbs Up

    Could scale have made that branch fall off? How do I kill scale?

    You kill scale with horticultural soap/oil in late winter or insecticide in July (crawler stage)- I don’t know which one tho as I’ve never treated in july.
    Systemic (mauget) will kill it ... timing is difficult with contact
    Clean up leaves late winter early spring too
    That’s not scale
    Scale doesn’t do that

    Mauget with a mild insecticide will kill those buggers
    Mauget is like setting up an IV for trees

    But, legally you need to know what pest you have first to treat before you do so.
    I’m not sure from the pics what it is but I know what will kill it!
    Lol

    Looking at other pics
    The tree dies have oyster shell scale
    But it’s also got something else
    The scale isn’t going to bore inside the tree Like that

    Texas is well south of my scope of knowledge, as I'm in Michigan.
    Does this tree flower? If yes, then maybe Crape Myrtle.
    But have someone with a hands-on knowledge of southern plant-scapes take this one.
