Missing driver for idVendor=0bda, idProduct=b812, bcdDevice= 2.10

Running Tumbleweed and did a dup the other day, now my USB dongle, fails to load driver:

Bus 002 Device 006: ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]

Believe I previously had a repo provided by Sauerland that has worked fine for ages, but the update seems to have killed/deleted it.
Have manually gone in and installed:
rtl8812AU_8821AU-kmp-default-20220408_k5.19.8_1-3.8.x86_64.rpm rtl8812AU_8821AU-ueficert-20220408-3.8.x86_64.rpm
from: https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Tumbleweed/x86_64/
then ran Yast>Software, and it updated to something that looks the same?

Obviously something is not working…
When I connect the dongle, message from journalctl:

Thanks.

Isn’t “rtl8822bu-kmp-default” more likely the correct driver?

https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Tumbleweed/x86_64/rtl8822bu-kmp-default-git20220820_k5.19.8_1-15.11.x86_64.rpm

Maybe give that a try, or wait for the definitive answer from @sauerland

modprobeid 0bda b812
Kernelmodulname rtl8822bu

So as @tannington has said, its an rtl8822bu Chip.

As root:

zypper ar -f https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Tumbleweed/ Sauerland-Hardware

Install as root:

zypper in rtl8822bu-kmp-default

That will install the kmp and the uefic cert needed for secure boot.

If you use secure boot and example is here:

My cert:

/etc/uefi/certs/F2B7BCC9.crt

If you get an Kernel-Update, wait to get the update of my kmp, because sometimes it will work without installing the new kmp, sometimes not.
That depends on the changes of the new kernel.

Perfect! Done and back online.
Will try not to stuff up next time…
Thanks a heap!
