HID QUIRKS(9)

✨ HID quirks ✨

okay so bestie, welcome to the HID quirks page 💅 it's page nine of the Kernel API Manual, and honestly? it's giving "notes app at 2am." the whole thing is basically a vibe check on the quirk flags that live in the kernel's HID header, and this page just... lists them. no descriptions. no lore. just names. iconic behaviour, honestly 🎀

the quirks live in the kernel file ./include/linux/hid.h, and here's the full lineup — every single one, no skipping, we don't do that here 🫶:

• HID_QUIRK_NOTOUCH
• HID_QUIRK_IGNORE — ignore this device
• HID_QUIRK_NOGET
• HID_QUIRK_HIDDEV_FORCE
• HID_QUIRK_BADPAD
• HID_QUIRK_MULTI_INPUT
• HID_QUIRK_HIDINPUT_FORCE
• HID_QUIRK_ALWAYS_POLL
• HID_QUIRK_INPUT_PER_APP
• HID_QUIRK_X_INVERT
• HID_QUIRK_Y_INVERT
• HID_QUIRK_IGNORE_MOUSE
• HID_QUIRK_SKIP_OUTPUT_REPORTS
• HID_QUIRK_SKIP_OUTPUT_REPORT_ID
• HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP
• HID_QUIRK_HAVE_SPECIAL_DRIVER
• HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE
• HID_QUIRK_IGNORE_SPECIAL_DRIVER
• HID_QUIRK_POWER_ON_AFTER_BACKLIGHT
• HID_QUIRK_FULLSPEED_INTERVAL
• HID_QUIRK_NO_INIT_REPORTS
• HID_QUIRK_NO_IGNORE
• HID_QUIRK_NO_INPUT_SYNC

lowkey obsessed with the fact that the only one this page bothers to explain is HID_QUIRK_IGNORE, which it helpfully tells us means "ignore this device." thank you bestie, truly groundbreaking 💀
