USB warm up

[Guest]

Hello, I have a usb wifi device which works well on nano pi neo 3.4.113-sun8i.

I update to the latest ditribution 5.15.48-sunxi jammy, then I rebuild kernel drivers but now it only work on a cold boot and when I hot plug the adapter.

On a warm boot the adapter with lsusb is ok but nmcli can't find the device.

I have the same problem with another usb wifi adapter (lsmod is ok, but stil not working with "rmmod 8821cu" and then "modprobe 8821cu")

I installed drivers from a fresh install (5.15.48-sunxi jammy) :

git clone https://github.com/brektrou/rtl8821CU.git 
cd /usr/src/rtl8821CU
./dkms-install.sh
apt install usb-modeswitch

 

Must I do someting at reboot ? Are there known bugs ?
