Hi all,
I’m troubleshooting an I-PAC Ultimate I/O board that’s currently stuck in Keyboard mode after a firmware reflash. Hoping someone here has seen this behaviour or can offer insight.
🧰 Setup & Background
- Board visually resembles the I-PAC2 layout shown on Ultimarc’s site
- Previously worked in XInput mode, LED was active, inputs responsive
- WinIPAC V2 used for mapping and firmware upload
- After reflash, board now shows as “Ultimate I/O” in WinIPAC V2 (Board attached: uio)
- LED no longer lights up, hotkey combos don’t work, and XInput won’t activate
🧪 USB Descriptor Info
- Device Manager shows:
USB\VID_D209&PID_0412&REV_0056
USB\VID_D209&PID_0412 - This PID isn’t listed for standard I-PAC2 or Ultimate I/O — possibly a newer revision?
📎 Screenshots Available
- WinIPAC V2 layout and status bar
- Firmware uploader window
- Device Manager with VID/PID
- joy.cpl test panel
- Photo of the board itself
📬 Support Request
I’ve contacted Ultimarc and requested the correct .ufw firmware for Ultimate I/O with multi-mode support. In the meantime, I’d love to hear from anyone who’s:
- Seen PID_0412 before
- Recovered from a similar firmware lock
- Has tips for restoring LED/XInput functionality
Thanks in advance — happy to share screenshots or test suggestions.
Cheers,
Mark
