A friend who used to do tech support told me that he learned that instead of asking "is it plugged in" it was better to ask the customer to unplug it and plug it back in. Then they might notice that it was unplugged but they don't have to admit it. I think about that a lot
100% but also, it's inherently less condescending and usually just a good approach if it's a USB peripheral where reforcing driver install can sometimes lick it. Or a different port can. There's a little more holisticism in it.
And yeah, I've wracked up 200 calls this month where a portion were Topaz pads or various scanners and a reseating was half the trick. The other half was then selecting the right Twain in the EHR.
