Hi,
Upon issuing "lsusb", I got a feedback after about 33 seconds. Sometimes, it's immediate though.
Trying to insert various USB keys or drives, it seems BUS 1 is the culprit : I mean if I insert an oldish USB key which connects on BUS 1, it takes a long time to appear as a new device. But if it's a faster USB device which connects on BUS 2 USB C (BUS 3 or 4), then it appears fast.
I'v tried to boot on Windows 11 (with another NVMe) and all is good.
This slowing down is fairly recent.
I get those messages all the time :
