Hy everyone.

Hope I’m in the right place to be asking this question, if not, please be kind enough to redirect me.

So, in a setup where we have a USB device connected to the Internal USB port of a Dell Poweredge R430 server and want to deliver it to an ESXi 6.5 Guest Debian VM (we know this is not best practices but please try to disregard the reasons, it’s where we’re at), we’re having an issue where in some situations, if the device is disassociated from a VM and we reboot the server we then start getting “USB Enumeration failed” errors or other USB related errors if we attempt to add the USB device to a VM, this happens until we are completely unable to find the device as available to be added to the VM, like greyed out in the interface. For what we gather to be able to find the device again we have to remove it physically, inserting it again and boot the server.

Really weird situation. Anyone has any ideas? We’re out. We tried with USB Passthrough options, disabled vmkusb drivers and we could not find much else to try.

Thanks.
