[PATCH v3 2/2] usb: Do not query the IO advice hints grouping mode page for USB devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
