I think these changes have broken my USB wheel mouse.
Events seems to be getting lost (/dev/input/mice)
It only scrolls when either the scroll direction has changed or if other mouse events occur (e.g. you need to wiggle mouse from side to side to scroll down a long page in mozilla)
problems seems to be in drivers/usb/hid-core.c hid_input_field line 772
for (n = 0; n < count; n++) {
if (HID_MAIN_ITEM_VARIABLE & field->flags) {
if ((field->flags & HID_MAIN_ITEM_RELATIVE) && !value[n]) continue; The next 2 lines are dropping the scroll wheel events (which appear in the input code as type:2, code: 8, value -1 or 1 depending on direction)
if (value[n] == field->value[n]) continue; hid_process_event(hid, field, &field->usage[n], value[n]); continue; }
Works fine in ac3. -- Michael. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
