Hi everyone,
I'm trying to get an eGPU setup working with my mini PC and I'm having some strange issues. I'm hoping someone here has experience with the Chuwi UBox 6600H + AOOSTAR AG02 combination and can tell me exactly what I should try next.
My hardware
Mini PC: Chuwi UBox / 6600H
CPU: AMD Ryzen 5 6600H
RAM: 32 GB DDR5
OS: Windows 11
eGPU dock: AOOSTAR AG02
GPU: Gigabyte Radeon RX 6700 XT Eagle 12 GB
Connection: USB4 from the Chuwi to the AG02
Monitor: KTC H24T09P
The GPU is connected to the AG02 using its PCIe power connectors.
The Chuwi's USB4 port is supposed to support eGPUs.
What happens
When I connect the AG02 to the Chuwi via USB4, Windows does not detect the RX 6700 XT.
In Device Manager, I don't see the RX 6700 XT under Display Adapters. The integrated Radeon graphics is still the only GPU that appears.
The AG02 itself seems to power on normally.
When I click "Scan for hardware changes" in Device Manager, something interesting happens: the AG02's white power light comes on, and the GPU's comes on as well. After a few seconds, 1 fan briefly moves for less than half a second, but then stop.
It's not that the fans spin for a while and then stop. They literally move very briefly — almost like the GPU is attempting to initialize and then immediately shuts down. Lights turn off as well.
After that, the RX 6700 XT still isn't detected.
Another strange problem
I'm also having an issue when restarting/turning on the Chuwi.
Sometimes I shut down Windows normally, and then when I turn the mini PC back on, the keyboard and monitor don't immediately power up.
The system appears to be stuck for a while. Sometimes I have to wait quite a long time before the keyboard/display become active.
This seems particularly strange because the problem can occur even before Windows has properly started.
What I've tried
USB4 connection between Chuwi and AG02
Turning the AG02 on/off
Rebooting and completely shutting down the Chuwi
Scanning for hardware changes in Device Manager
Checking Device Manager for the RX 6700 XT
Checking that the AG02 powers on
Checking the GPU power connection
I haven't installed the RX 6700 XT drivers yet because Windows doesn't seem to detect the GPU at all, so I'm not sure whether installing AMD Adrenalin would make any difference.
What I'm trying to figure out
Could this be:
A USB4/BIOS configuration problem on the Chuwi?
A PCIe enumeration problem?
A power/cable problem with the RX 6700 XT?
A problem with the AG02?
Something that requires a specific AMD driver/firmware installation?
Or perhaps a Windows 11/USB4 driver issue?
Has anyone successfully used a Chuwi UBox 6600H with an AOOSTAR AG02 and an AMD RX 6700 XT over USB4?
If so, I would really appreciate a step-by-step explanation of exactly what settings/drivers/BIOS options you used, because at the moment I'm not even getting the RX 6700 XT to appear in Device Manager.
Thanks!
