Hi,

I bought a Mantiz Venus to work as eGPU for my Razer Blade Stealth. It worked out-of-the-box to accelerate the internal screen (no external monitor connected).
What I want it to do, is let it work with my Oculus Rift, and I had no luck yet getting this to work.
I try to use it as an all-in-one hub, connecting:
- Oculus Rift via hdmi+usb 3.0
- 2 sensors on usb 3.0
- 1 sensor on usb 2.0 (actually the cable is usb 2.0, the port is 3.0).
Graphic card is a Gigabyte Geforce GTX 1080 G1 Gaming, and it seems to work properly: I could run the Steam VR test (score: 11), so this seems promising.
There is some stuff going on, but I cannot really pinpoint what's wrong:
- Sometimes HDMI connects succesfully
- Sometimes it looses connection
- I got an error once: not enough usb controller resources
- In my list of devices, I get 2 or 3 HID-devices that get a warning sign every couple of seconds.
- When trying to do the setup of the Rift, it detects the sensor, then gives an error message before it can complete the sensor setup.

Thanks for any advice!

The disconnected from hdmi is something my rig is currently suffering from also . I hope you get yours figured somehow and myself  also. I'm wondering if it is at all possible to plug the rift hdmi into the card it self for a good connection?

tested:
Yup did just that and Oculus Rift CV1 hums.

Any solutions found already?

I‘m having the same issues with Mantiz Venus (but on a macbook). USB disconnects every <1 second. It did run for a bit with one sensor, but with two it‘s a no-go (ideally one would have 3).

Does a switch to a different eGPU case fix this?
If yes, which one?

Late 2016 15" MBP w/ Radeon Pro 460, 2m CalDigit TB3 cable, Mantiz Venus eGPU case, NVidia GTX 1080ti.
