Hi

║ Upgrade USB-C Dock G5 from 1.0.24.0 to 1.0.25.0?                             ║
╠══════════════════════════════════════════════════════════════════════════════╣
║ New features and enhancements:                                               ║
║                                                                              ║
║ • Enables button detection without checking TI ALT mode to fix issues        ║
║ where the system cannot power on via the dock power button when the battery  ║
║ is fully depleted and the dock is connected to a Type-C A/B port.            ║
║ • Resolves dock button functionality issues such as no sleep or              ║
║ power-off.                                                                   ║
║ • Adjusts DR_SWAP timing and enables Checked Message support to fix Wake     ║
║ on LAN failure from S4/S5 when the MAC address is disabled with a dock       ║
║ connected.                                                                   ║
║ • Resolves USB 3.0 disk detection failure on the dock (2nd source cable)     ║
║ when Hi-Res is enabled.                                                      ║

║ distorted when an HP monitor is running 2K at 60/75/100.                     ║
║ • Adds a workaround that causes the display to be blank when the host        ║
║ switches from FEC to non-FEC, resolving monitor text noise, white lines,     ║

Hello @counterroot ,

Welcome to HP Support Community.

Thanks for the very detailed report — that helps a lot.
What you’re seeing is a known limitation / incompatibility path rather than a fault with your dock or system.

Below are the recommended resolution.

Option 1 — Update Dock Firmware from Windows (Official & Safe)

This is the only fully supported method today.

1. Boot any Windows system (can be temporary)

2. Connect only:

   • HP USB-C Dock G5

   • Power adapter

3. Download firmware from HP:

   • Either via HP Support Assistant

   • Or HP Firmware Installer – USB-C Dock G5

4. Run the update

5. Wait for completion (dock will reset)

After this:

• Dock will be on 1.0.25.0

• You can return to Linux

✔ Firmware is stored in the dock, not the OS

---

Option 2 — Stay on 1.0.24.0 (Also Valid)

If you are not experiencing:

• Dock power button issues

• Wake-on-LAN failures

• Monitor flicker / EDID problems

Then:

• 1.0.24.0 is stable

• No functional risk staying on it

• fwupd correctly prevented a bad flash

The dock remains functional and unmodified. Firmware updates for this device must be performed using HP’s official Windows-based firmware tools. Please feel free to contact for more information.

Hey,
Not sure what fixed the issue for me, but:

I had issue on my work HP laptop with Ubuntu 24.04 (fwupd installed from snap because it needed version 2.0.8)
fwupdmgr didn't pick the latest FW 1.0.25 so I tried downloading https://fwupd.org/lvfs/devices/com.hp.Dock_USBC_G5.ccgx.dmc.firmware and install manually (using fwupd.fwupdmgr because is the snap installed version 2.0.18) using with the same error

root:~# fwupd.fwupdmgr install ./USBC_DOCK_G5_V1.0.25.0.cab 
Decompressing…           [                                       ]
constant FuStructCcgxDmcFwctInfo.signature was not valid, expected 0x54435746 and got 0xffffffff

I managed to install new FW successfully on my old laptop on Fedora 43 with the default fwupd 2.0.17.
Installed the downloaded FW, but didn't try "fwupdmgr upgrade"
Also, not sure if it was version of fwupd,  Fedora Linux or the fact that my old laptop doesn't have USB-C and I just Upgraded using USB-A to USB-C adapter 😄

Hope you get it working
