And mine
regardless, this is not getting @Kdude0 problem sorted
I wonder if there is a fault on the PCB, a short or loose connection.
You tried
update
different cables
different computer
Sorry if I missed it, but have you had any success with anything on it, ever?
Maybe it’s DOA!?
I appreciate all the help and suggestions so far. 
I actually never got this Proxmark working on any computer to date yet. I had tried to get it working this past fall when I got it, then I went on vacation, and it got put on the back burner as far as projects ever since until now. This could be a slight change in the port position/button and stuff since @amal was waiting on a new shipment at the time when I did order it. A couple of other things I forgot, I did do that swap in the makefile.platform. Also, tried the DT diagnostic card with it now too, and am not getting any LF signal from on an LF Search. It does give me HF signal, however it hasn’t been able to read a HF tag yet tho. Here is a screenshot of the HF tag I was trying to read with it, this is NFC Tools on my phone reading this…
Hmm at this point I think it might be worth swapping you.out. reply to your original order confirmation email and request a replacement.
Hi Amal, I sent you an e-mail back at amal@dangerousthings.com with my original order number. I could also click the Famous Floaty Orangy Buttony Thingy Jiggy if you want. 
We need a glossary with all of these terms defined.
Update: I want to say thanks @amal for the replacement Proxmark3!! I got it this week and it worked right off the bat. I really appreciate the help. I thought I was doing something wrong or had communication issues on my computer end but it actually was a bad Proxmark. The fun begins now as I learn how to use it!! (P.S. Let me know if you want me to do anything with the old Proxmark yet…)
