installer can't detect my usb adapter

[lou <loushanguan2015@sina.com>]

i have realtek 8188eus usb adapter, it works in buster

but after reboot, it can't be recognized, i have to unplug and plug usb 
adapter to help detection. this isn't big inconvenience for me because i 
rarely reboot

my problem is bullseye installer can't detect it even after i unplug and 
plug it. i run "modprobe r8188eu" in installer's terminal, it doesn't  
help detection. lsusb command doesn't exist. if wifi isn't setup by 
installer, then i am unable to setup it after installation because of 
some debian bug
