Trinket 1500, USB Device not recognized

by DKing01 on Fri Jun 25, 2021 6:28 pm

Hello,

I think I may have a bad batch of trinkets from my last order on May 26th.
Order ID 2575835-1690961490

So far I have 58 trinkets that say USB device not recognized. All of the red LED lights do not light up as well when plugged in.
The other 100+ that were tested today were fine.

I am going through the rest of the batch that was ordered to make sure there aren't any more with issues.
We have ordered thousands of these, and never have had this many with issues.

Thank you

Hello,

We have a total of 306 trinkets that says "USB Device not recognized".
58 out of the 306 have the board pins soldered on before we caught the issue.

Please let me know what we can do to resolve this issue.
Thank you

Hello,

I apologize. I missed a few more. I also have 8 trinkets that have no power. The LED's do no light up.
Total of 314 trinkets.

Thank you

Just to be sure on the testing - everything else is the same? Same USB cable, same USB port, same host PC, etc? Only thing different is the Trinket itself?

Please keep in mind that version of the Trinket is deprecated. See warning on top of product page.

It sounds like maybe your use case is for a pre-existing use that depends on that specific Trinket? That's totally fine and why they are still made available. But just want to make sure you are aware of the hardware deprecation as well.

whats odd is absolutely nothing has changed with the programming and setup of the trinkets - we have the same components and testing procedure... so its a bit odd to get a large qty with issues
you're going thru a USB 2.0 hub?

Correct. Everything on our end is the same for testing and programming all of the trinkets.

I thought it was odd, as I have never seen such a large amount with issues before. I believe the last batch we had ordered was around 500, and 300+ aren't recognized. The rest of them were fine, and were detected with the same cable, port, and computer used. I even also tried connecting them on a second computer we have setup for programming the trinkets, and it did not connect for those ones either.

We have tested another 200 from a new batch that we just received, and have not had any issues with those..so the issue was only with that batch of 300+ units.

Thank you

Can I please get an RMA / exchange for these?
We are sitting on over 300 that we cannot use.

Thank you
