@Mymantiz_John: I have the same problem as OtaXou: If I connect a mouse to a USB port on the Venus, the cursor starts lagging. In addition, if I plug a USB sound card into the Venus the sound is lagging, too. I think someone had this problem earlier, but it was never solved. 

Please add our Twitter or FB, then we can guide you how or understand more in detail.

Hi Everyone, 

First, thanks for all the extremely helpful guides and information on the site. Using all the info here I've been able to get my late-2016 15" Macbook Pro hooked up to a Mantiz Venus with an EVGA Geforce GTX 1080 Ti and the card has been running smoothly in MacOS Sierra and Windows 10, with one exception.

I've noticed under Windows 10 that the USB ports on the Mantiz Venus are completely unusable while the card is under load. If I plug in my keyboard and mouse they light up and seem to work fine when just browsing through Windows. If I start to play a game though they seem to repeatedly cut out and lag extremely badly - input from both freezes for 1-2 seconds at a time and makes them completely unusable. 

I've had to get around this by plugging everything in directly to the laptop. That works fine, but I'm extremely disappointed that these don't seem to work since having an all in one docking solution was what drew me to buying the Mantis Venus in the first place. At this point I'm a little frustrated I've paid the premium for the Mantiz Venus over a simpler solution like the Akitio Node

Has anyone else experienced this? Are there workarounds or solutions for this issue? I've looked around but can't find others complaining of this issue. 

Thanks!

I'm experiencing the same issues. When on load, my headset (which is usb based plugged on Mantiz) stops for 1-2 seconds often. It doesn't happen when I plug it directly on my Macbook.

2017 15" MacBook Pro (RP555) [7th,4C,H] + GTX 1080 Ti @ 32Gbps-TB3 (Mantiz Venus) + macOS 10.12.6 & Win10 [build link]

I would suggest you to load the previous FW to test, contact us through FB or Twitter, we'll guid you how.

I just had a similar experience on my 15" MBP on OS X 10.12.6. On a heavy render in Octane Cinema4d my USB mouse suddenly disconnects, whether connected front or rear ports it happens. Has this issue been resolved or confirmed?

I am having the same issue. All my USB peripherals flicker on and off constantly. I have been on the latest FW since the day it was released but the issue only just started now. I do not want to roll back to previous FW and suffer H2D loss but the unusable USB ports almost make me feel the need to do that. My eGPU isn’t even under load when it happens.

I have messaged Mantiz on FB, hoping for a response soon.

UPDATE:
Got in touch with Mantiz, they are about to send me a link to the fixed firmware. Will unfortunately result in losing the H2D gains from September FW update but I would rather have my USB ports work.
Going to test the FW later and update here with results and tell you guys if USBs are working again.

Will there be a Mac installer for the firmware? I don't have a Windows machine nor do I use Bootcamp.

The firmware sent to me by Mantiz appears to have fixed the USB issues. All my peripherals now functioning correctly.

Unfortunately, it is confirmed that this FW results in losing the H2D gains from September FW update.

Thank you at @Mymantiz_John for very fast support for fixing the issue. I would rather have fixed USB ports than 500-600 extra mib/s bandwidth for H2D.

In the future, I would like to see new firmware that features H2D gains AND USB ports fixed. I hope they are working on this.

@mustardseedsg, the FW package that Mantiz sent me appears to include an OS X installer. I recommend contacting Mantiz on Facebook to get the firmware.
