Hello,
In reference to this bug: https://osmocom.org/issues/5310
I am also experiencing this on two different platforms, Pi4 and an Intel NUC x86. I have two OCTSIMs but I can reproduce with one only and with only USB connected. All SIM slots are populated. Upon power cycle of the host system, the OCTSIM is unable to enumerate. If I unplug the USB cable and replug, it sometimes enumerates. If it doesn't, I move to another USB port and sometime it works.
I also tried upgrading the firmware on one board from 0.2.61-2a78 to 0.2.78-62e1 but the problem remains. Log below shows enumeration errors after which I unplugged the cables and replugged. Please advise as we cannot build a product around a device that cannot enumerate reliably.

I think this sounds more like a support / RMA case that should be discussed with sysmocom as the board manufacturer. If you have two units running the same firmware version and the setup works with one board, bu then if you swap in the other board things start to fail, it's a good indication of some hardware related issue that should be investigated and either repaired or replaced.
Please contact support@sysmocom.de for setting things in motion - no need to include the wider community on this mailing list.

Hi Harald,
I don't think this is an RMA concern as both boards exhibit the same enumeration behaviour regardless of running firmware as highlighted in the bug I provided a link to, unless they're both faulty which seems unlikely? Once enumerated, they work. Happy to raise an RMA if you still think this is the case.
Regards

My apologies, I misread your statement "I have two OCTSIMs but I can reproduce with one only and with only USB connected. ". To me, this sounded like the problem is only reproducible with one of your two boards. If it is reproducible with both, then indeed it is more an indication of a software problem.
