I have some arm64 hardware (rockPi5)

booting ubuntu 22.04 on a m2 and everything works.
changing for an m2 running bookworm and the (same) firmware is not loaded.

[ 5.182099] usb 1-1.2: new high-speed USB device number 3 using ehci-platform
[ 5.380310] usb 1-1.2: New USB device found, idVendor=2040, idProduct=0265, bcdDevice= 1.00
[ 5.380331] usb 1-1.2: New USB device strings: Mfr=3, Product=1, SerialNumber=2
[ 5.380346] usb 1-1.2: Product: dualHD
[ 5.380359] usb 1-1.2: Manufacturer: HCW
[ 5.380371] usb 1-1.2: SerialNumber: 0014053495

but the firmware is not loaded

[sandypit] /home/jam [108]% /bin/ls /lib/firmware/dvb-demod-si2168-*
/lib/firmware/dvb-demod-si2168-02.fw /lib/firmware/dvb-demod-si2168-b40-01.fw

(the /bin bit is quick way for no colour)

Does debian do something strange?

Depends how and where you built that bookworm M2.

In Debian 12 the devs relaxed their restrictions on non-free firmware, so that when you do an
install all the firmware required for the hardware /present at the time/ is loaded.

If you have then taken that M2 and plugged it into a different host where the hardware is different,
you won't have the required firmware.

This has just happened to me, incidentally, on a non-myth project. I had to move a HDD from one
motherboard to another, and the second one has Realtek NICs where the first had Intel. Workaround:
'apt install firmware-realtek', which I would have had to do anyway on previous releases.

Mike thankyou.
I built the m2 on a usb-m2 adapter (on my laptop)
Like RaPi the FS is expanded at first boot.
All my SW built without a hitch (logger stuff, mythbackend). In this case I had to spelunk Haupauge to get the firmware.
A quick apt look. Nothing rears its head.
I'll try things now that I know.

I rue the lack of 'This is what we've done'. As a mere mortal you dont need to know ...
