USB-C key fails to update

[rosanows]

I can update my USB-A key without issues, but I cannot update the USB-C key. However they arrived with totally different firmwares. USB-A was already on a 2: one, USB-C is still on 0:
I also tried this on different machines using macOS and Windows 10.

It's not a hacker edition, is it?

[rosanows]

It should not be. Both USB-A and USB-C were ordered as non-hacker edition.

But that's an interesting hint.
A shows as Bus 001 Device 007: ID 1209:beee 1209 Solo 2 Security Key Serial: 5CE9DA5C86E5585FBBAF38468FC4A0F1
C shows as Bus 001 Device 008: ID 1209:b001 1209 Tester Serial: 24C0505B74AFCA5F9479D2AAE5968B16

Could it be a non-prod device?

[JohnLGalt]

Hmm. The fact that it says Tester does seem to indicate that. But I'm not associated with the company in any way, so you'd have to ask Connor Hayden.

Hayden is usually super quick to respond when sending email to the support channel, but it has been a long while since I contacted them, so YMMV.
