[Linux users] Stealth Ultra wireless dongle now works on Linux - and a request for Turtle Beach
For anyone trying to use the Stealth Ultra controller on Linux (regular distros, Steam Deck, etc.):
Good news: the wireless dongle works once the Linux xpad driver knows about it. The wired connection has been supported since kernel 6.15, but the dongle uses a different USB product ID (10f5:7070 vs 10f5:7073) that wasn't in the driver. A one-line addition fixes it - the dongle itself is transparent and uses the standard Xbox protocol.
For Linux users today: until the patch lands in the mainline kernel (PR submitted: https://github.com/paroj/xpad/pull/364), you can build a small DKMS module yourself. Full instructions in this r/linux_gaming thread: Tutorial in linux_gaming
For Turtle Beach: both the wired and (with my pending patch) wireless Linux support came from the community, not from you. It would be appreciated if future controllers either shipped with upstream Linux kernel patches submitted by you, or if you at least documented the USB protocols so the community doesn't have to reverse-engineer them.
Also: a Linux version of Control Center 2 would be a big deal - or open documentation of the firmware/config protocol so the community could build one.
Hardware itself is great - the wireless latency feels instant compared to BT. The only thing keeping it from being "perfect" on Linux is one missing line in a driver table that the community has been quietly fixing for you.
Thanks!
