USB Passthrough vmkusb issues

[Horst69]

Hi,
I have a problem with USB passthrough.
The vmkwarning.log is full of USB warnings.
Do you know these error messages. What can I do?
I use version 7.0 update 3

Thanks a lot

I am seeing the same issues but on Esxi 8 - I attached a 4TB Toshiba SSD to the lab server (Intel NUC NUC11TNHi5) and start seeing these warning messages in the vmkwarning.log file. When the USB drive is unplugged, the warnings go away. The SDD is passthroughed to a Windows 10 Pro virtual machine and appears to work.

Any insights on what is going on is appreciated.

All the best

Peter

Just a thought - I'm using a Toshiba Canvio Basics 4TB portable external SSD that claims to support both USB 2.0 and 3.0 interfaces. Would these errors be caused by plugging the drive into the back USB 2.0 port on the NUC? Peter
