So I assume you use have a wifi dongle, connected to the hub, that communicates with the tethered phone's hotspot. > i don't have usb disk plugged to usb hub So what's the hub for? > bookworm for both i386 and amd64 seem uncomfortable with my usb hub. > > last few lines below show errors > > i am now using bullseye, bookworm isn't stable enough for me Just because of this hub, or for other reasons?
