Hello,
I just received 35qty trinket pro 5v and none of them will work when I plug in the usb to upload a sketch.
I had a few boards left from previous order from a few months ago and those work great as usual, as well as a couple used ones I had laying around. This entire new batch I just got seems to be defective.... When I plug them in I only get a green LED and does not get recognized

Re: Trinket pro 5v bootloader not working
Can I get an RMA to return these? I need to get some working boards asap...
I see you guys are actively trying to phase out these trinkets... I would not be opposed to trading these for itsy 32u4 5v
Hopefully I can get some help so I can move forward with this matter.
Thanks

Re: Trinket pro 5v bootloader not working
I little help with this issue in a timely matter would be nice.
They tell me i have to post here in order to start the return process
This entire batch of boards do not work.
I have new boards(same thing) from a previous order and they work fine. As soon as i pull one from this new order the red light doesn't not come on or get recognized by the computer. I have went back and forth done this process several times to prove that it is this batch of boards, not my doing.

Re: Trinket pro 5v bootloader not working
Just to make sure - everything else is the same in your testing? Same USB cable, port, computer, etc. You're just swapping older/working Trinket Pro's for one from recent order and seeing the issue?

Re: Trinket pro 5v bootloader not working
Yes you are correct.
I had 5 left over from a previous order from this one, burned them as usual, turned around opened the drawer grabbed this new bag of 35 to burn and tried a couple with the same not working result so i went back to the first 5 I burned and was able to reburn all those just fine. I have since tried 16 of the 35 and they all do the same thing(just a green light and do not get recognized by the computer)
So yes, I know my cable is good and I even tried another one to be sure. I even have some other trinkets around and all of those work fine. Just these 35 so I'm not sure what's going on with them.
Thanks for the help

Are you sure the Trinkets are all the same? (Just checking.)

Re: Trinket pro 5v bootloader not working
when you press the reset button, does the red LED ever come on/blink/pulse?

Re: Trinket pro 5v bootloader not working
Yes they are all the same, Trinket PRO 5v
No, i do not get a red LED. Only a green one is illuminated
GOOD Boards (like my previous orders) turn on a red led when first plugged in (bootloader mode) then turn off after a few seconds. then back on again when you press the button.
On this order of boards when i plug in there is only green. when i press the button the computer dings after several seconds. if i try to upload it gives me an error: could not find USBtiny device.
