Hi,
I noticed that support for Realtek's 8821cu devices was recently merged with
commit aff5ffd7. I have a "Realtek Semiconductor Corp. 802.11ac NIC" (ID
0bda:c811) so I decided to try 6.2rc1.
However I only get these messages (and no new wifi network interface) when
trying to load the module:
rtw_8821cu 1-4:1.0: Firmware version 24.11.0, H2C version 12
rtw_8821cu 1-4:1.0: rfe 38 isn't supported
rtw_8821cu 1-4:1.0: failed to setup chip efuse info
rtw_8821cu 1-4:1.0: failed to setup chip information
usbcore: registered new interface driver rtw_8821cu
I read that the vendor-supplied GPL driver (which I don't use) requires
"usb_modeswitch" so I ran that just to be sure but still no dice:
$ sudo usb_modeswitch --std-eject --verbose --default-vendor=0bda
--default-product=c811
[...]

Look for default devices ...

Found devices in default mode (1)

Current configuration number is 1

with class 255

Is there a new branch I could try? Any idea what I am doing wrong?
