On recent LE 11 nightly builds (from about 20211224) I am experiencing the USB resets which are fatal due to DVB-T2 USB & USB/SATA adapters connected.
It looks an old bug already fixed couple months ago is back in the 5.15.10 kernel, at least on RPi 4B with TVheadend 4.2 / 4.3 & Tvheadend HTSP Client.
Usually the USB reset happens after DVB-T2 channel switch to another one. It happens randomly but quite often.
