if it can decode Ethernet protocol too, that would be nice.

Logic analyzer is a wrong tool for this. You need specialized USB protocol analyzer for the task. I'm sure there are universal logic analyzers which can work with USB, but the cost will be insane.

Your first problem will be to ensure signal integrity when you attach a probe to a high speed (i.e. analogue) line.
There are lies, damned lies, statistics - and ADC/DAC specs.

His second problem is to stop asking wildly random short questions.

Yes. And us answering them!

Perhaps they'll learn something from https://entertaininghacks.wordpress.com/library-2/good-questions-pique-our-interest-and-dont-waste-our-time-2/ but I won't hold my breath.

  • reassessing directives...
#1) long question, not understandable = -10 ^ 3 marks
#2) short question, not understandable = -10 ^ 2 marks
#3) long question, understandable = -10 ^ 1 marks
#4) short question, understandable = 10 ^ 3 marks

the OP's question is #4... but that just my intellectual interpreting it. this ever growing forum is filled with either question type #1 or #3, majority.
if something can select, how cant it be intelligent? if something is intelligent, how cant it exist?

This user has posted a lot of one liner questions with no background. In fact the typical pattern of posting of somone wanting to spam the forum. They fill the forum with nonsenical posts that are borderline and then put spam in their signature as it retrospectively updates on all posts. they obviously massively over estimate how long it takes to just delete their account and all of their posts as well. Or he is trying to get his post count up for some competition, another user has alreasy been banned for that, this one is getting close.
