Recently it was reported that the following USB storage devices are unusable with Linux kernel 6.9: * Kingston DataTraveler G2 * Garmin FR35

This is because attempting to read the IO advice hints grouping mode page causes these devices to reset. Hence do not read the IO advice hints grouping mode page from USB storage devices.
