Title says about the most of what I know. Im really green to vmware and Im not sure what any of that means. I tried looking it up and it looks like some people say its an issue with the DRAC? Its on a Poweredge R730xd and the DRAC has never been setup and Im not sure if the firmware has ever been updated for it. Not likely due to the nature of my work and the facility Im in. Just want to know what this message means for the performance of the host, and what I can do to get rid of it.
Thanks
Hello whw8448
"That knowledge base article looks like its for if ESXi is on a USB drive but this host is on a Poweredge R730xd."
I gave that as an example of likely error messages - it is potentially any USB device that is generating this, SD-cards (from which this host likely boots) are a potential source, as are out-of-band management tools (iDRAC on DELL) which create virtual-USB devices (e.g. virtual-keyboard).
Do you have any pass-through USB devices connected to this server? If so, make sure they have correct drivers, are compatible and supported etc.
If there are no pass-through devices then try restarting usb arbitrator:
# /etc/init.d/usbarbitrator stop
# ps | grep vmware-usb (to make sure all threads have been killed)
# /etc/init.d/usbarbitrator start

Hello @whw8448,
Can you give more context as to where you are seeing this error message and the full error message? (Screenshots may help)
e.g. "URB timed out - USB device may not respond"

If you are seeing the error message pop up in the GUI from time to time, then check in the alarm/events logs section of the host GUI interface for more verbose information relating to these.

I am seeing them in the events tab on vcenter for this particular host. Yes its giving me that exact error URB timed out USB device may not respond. I wont be able to provide screenshots because the system is secured. The alert is coming in about 20 times every minute. That knowledge base article looks like its for if ESXi is on a USB drive but this host is on a Poweredge R730xd.
