Issue with Terra Front Panel USB C connection on ASRock B650I.
SFX build fresh release (avoid buying Lian Li SP750, its low RPM claims aren't true). Fractal Terra features a USB 3.2 Gen 2x2 front panel connector, but my device uses a Gen 1 type C port. They work together without issues. I connected my DAC to the front panel USB C (IBasso DC03) but received a "usb device malfunctioned" alert. Removed it, restarted—still no issue. Updated devices, uninstalled and restarted, no change. Tried disconnecting and plugging in a cheaper DAC from Amazon; it functioned but acted oddly. Continuously paused a YouTube video as if holding down the space bar. Finally, using an Anker C USB hub resolved the problem. (Can't connect DACs to the hub.) Windows 10 Pro, 64-bit. BIOS on B650I: 3.30 Is there an incompatibility between Gen 2x2 and Gen 1 connectors? It seems Gen 2x2 is just two lanes of Gen 2, which I assumed was backward compatible.
I noticed your message and wanted to add my experience — I encountered a very similar situation and found a solution that worked well. The front USB-C connector on the Fractal Terra uses USB 3.2 Gen 2x2, but most motherboards (particularly ITX models) only provide a USB 3.2 Gen 1 internal Type-C header. Although the physical fit is correct, the internal wiring and supported features don’t align properly. In my setup, I faced problems such as DACs failing, “USB device malfunction” warnings, and some peripherals behaving erratically. When I connected those same devices to the rear USB-C port, everything functioned normally. From what I observed (and based on your setup), the front port likely lacks the necessary power delivery or high-speed capabilities for certain devices like DACs. Cheaper or low-power gadgets sometimes work, but more demanding ones tend to have trouble. Unfortunately, there’s no easy workaround without a board that supports Gen 2 or 2x2 internal USB-C. In the meantime, I suggest using the rear USB-C port for devices requiring stable power and fast data transfer, such as your DAC. You might consider getting a SilverStone ECU06 or similar to address this issue.
You found my advice really helpful. It’s cool I’m facing the same problem. Fun to discover this too. Maybe keep it connected for non-essential stuff, and use the rear port for serious USB C devices or DACs. Disappointing though.
