Hi,
I saw the 8821cu chipset being merged for linus' next kernel release and
decided to give it a try. I have been running 8821cu from
https://github.com/morrownr/8821cu-20210118 succeffully, so I know my
hardware works.
The driver as merged in commit 07cef03b8d44dee7488de3d1585387e603c78676
to git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
can't find any firmware for the driver, and the card does not work. At
boot it repeatedly logged failures to my kernel.log:

There is no mention of what firmware would be needed in the source code
itself, yet the repository https://github.com/ulli-kroll/rtl8821cu
includes a file firmware/rtl8821cufw.bin.
I don't know whether this needs another big update before linus merge
window for 6.2 closes, so I chose to report it early.

The firmware that is needed is the same as for the PCIe nersion, namely
/lib/firmware/rtw88/rtw8821c_fw.bin. Your distro should have that firmware in
package firmware-realtek, or in linux-firmware-realtek. If they do not, you can
get it by 'git clone
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git. The
firware will be in directory rtw88.

That file is installed on my system, yet I get the above error messages.
$ ls -l /lib/firmware/rtw88/rtw8821c_fw.bin
-rw-r--r-- 1 root root 139472 Dec 16 17:54 /lib/firmware/rtw88/rtw8821c_fw.bin
$ sha1sum /lib/firmware/rtw88/rtw8821c_fw.bin
69c087a1963953c2e0e8a8338237e0689b4d7c40 /lib/firmware/rtw88/rtw8821c_fw.bin
So something else must be broken. I'll try the rtw88 driver from ulli
krolls git repository later.

That means that firmware 24.11.0 was loaded, which is the latest in
linux-firmware as of this writing.

I have noticed the same messages on an 8821cu based adapter. There is
something wrong with the driver as opposed to missing firmware.
