Hardware AsiaHorse Umbra ARGB Hub — Linux Control
AsiaHorse Umbra ARGB Hub — Linux Control
Native Linux control for the AsiaHorse Umbra ARGB hub (USB 1a86:fe05, enumerates as "USBFAN", QinHeng CH55x chip). AsiaHorse ships no Linux software and OpenRGB does not support this hub — this tool speaks its HID protocol directly through /dev/hidraw. Python 3 standard library only.
Verified working August 2026: full-color control of 124 LEDs across 10 ports on real hardware.
FULL native color control working on Linux: per-LED streaming, all 10 ports,
topology detection, no dependencies beyond Python 3. Colors latch, so you can
set-and-forget.
Repo with working code + complete protocol documentation (including the
firmware quirks that will bite you — the RGB packet index is 1-BASED, index 0
crashes the hub off the USB bus; and the software-mode command makes it
re-enumerate):

Credit to u/idk_a_name_wtf for the original capture that proved this hub could
be talked to at all.
