✨ NAME ✨

huion-switcher — switch Huion tablets to vendor reporting mode 🖊️💅

---

🌸 SYNOPSIS 🌸

huion-switcher [--help|--version] --all|<path>

---

🦋 DESCRIPTION 🦋

so what does this little program actually do? it takes your Huion tablet devices and switches them from the default firmware reporting mode to the vendor reporting mode. that's the whole vibe. 🫶

in vendor mode the device uses a HID vendor collection to report input data in a more precise and device-specific manner than firmware mode. it's giving glow-up, honestly. some device features may only be available in vendor mode. 👑

but — and this is the important part, no cap — vendor mode requires either a kernel driver or a HID eBPF program to interpret the vendor-specific HID reports. so don't just flip the switch and walk away, bestie. 😭

if you intend to use HID eBPF programs (see udev-hid-bpf(1)) for Huion tablets, you will need the tablet in vendor reporting mode. that's the requirement. periodt.

huion-switcher prints several strings in the KEY=VALUE format. these strings should be passed to the HID eBPF program to allow for device-specific behavior. use the udev rule provided in the huion-switcher repository to ensure the properties are passed correctly. 🔥

💅 OPTIONS 💅

• --all — attempt to switch all connected Huion devices to vendor reporting mode. ⚠️ heads up though: Huion's USB Vendor ID (0x256C) is re-used by other vendors (e.g. Gaomon) and thus any such devices will also be switched. yes, really. they're sharing an ID like it's a Netflix account. 💀
• --help — print help and exit. the classic. the icon. 🌈
• --version — print version and exit. also iconic. ⭐
• path — a sysfs path to the device. typically this invocation is used with a udev rule. it is possible to use a hidraw path via the /sys/class/hidraw/hidraw*. 🧚

🎀 INVOCATION VIA UDEV 🎀

the recommended way to use huion-switcher is to install it in /usr/lib/udev and invoke it automatically via the 80-huion-switcher.rules udev rule on device plug. 🔌✨ the udev rule can be found in the huion-switcher repository.

bestie this is the main character energy way to run it. plug in, rules fire, tablet switches. effortless. 💖
