HID: usbhid: fix deadlock in hid_post_reset()

2026-04-09T15:48:05+00:00

You can build a USB device that includes a HID component and a storage or UAS component. The components can be reset only together. That means that hid_pre_reset() and hid_post_reset() are in the block IO error handling. Hence no memory allocation used in them may do block IO because the IO can deadlock on the mutex held while resetting a device and calling the interface drivers. Use GFP_NOIO for all allocations in them. Fixes: dc3c78e434690 ("HID: usbhid: Check HID report descriptor contents after device reset") Signed-off-by: Oliver Neukum Signed-off-by: Jiri Kosina

HID: pidff: Add MISSING_DEADBAND quirk

2026-02-26T14:46:00+00:00

Some devices (mainly Asetek) do not have deadband field in set conditional usage. Do not fail set conditional usage search if it's missing. Allows conditional effect playback on Asetek wheelbases. Deadband is practically never used in simracing anyway. Align property name in the whole driver to use 'deadband' without space.

HID: pidff: Add MISSING_NEG_SATURATION quirk

HID: pidff: Add MISSING_NEG_COEFFICIENT quirk

2026-02-26T14:46:00+00:00

Windows/Directinput allows devices with missing negative coefficient for conditional effects. Negative coefficient is ignored in such cases. Donot fail set_condition usage search if negative coefficient is missing. Fixes conditional effect playback on Asetek wheelbases. https://learn.microsoft.com/en-us/previous-versions/windows/desktop/ee416601(v=vs.85) Co-developed-by: Oleg Makarenko Signed-off-by: Oleg Makarenko Signed-off-by: Tomasz Pakuła Signed-off-by: Jiri Kosina
