   "modinfo rtw_8822bu" will give you some info on the driver, though   
   no direct info on how it was installed. On Debian (not RPiOS) I see   
   there are similar modules starting with "rtw88_" installed with the   
   base, but no "rtw_8822bu.ko". rtw88 apparantly supports your   
   TP-Link Archer T3U RTL8812BU device:   
      
   https://deepwiki.com/lwfinger/rtw88/1.1-supported-hardware   
      
   Check if you have rtw88 drivers already installed:   
    cd /lib/modules   
    find -name 'rtw88*'   
      
   If so, maybe you just need to blacklist the rtw_8822bu driver to   
   use them? Unless the rtw88 driver is used already and it wrongly   
   logs as "rtw_8822bu", in which case the "modinfo rtw_8822bu"   
   command will fail, and look at the output of "lsmod" to see   
   exactly which "rtw" module/s are being used.
