Unknown USB Device is getting detected on ProLiant DL380 Gen11

[Ragini19]

Hi,

I have  ProLiant DL380 Gen11. I am seeing unknown usb device on my machine.

Where when i checked physically there is no usb connected to node.

Question is why unknown usb device is getting listed on my machine?

Details i have collected so far :

I think this the ILO's virtual USB device, as it hints in the files you can find on it. Since it hurts no one, you can safely ignore it.

lsusb

May give you something human readable.

I think you need to go look at your ILO config. If you are using the remote console, that connects things to the underlying OS.

Not having a shiny toy like this to install an already End-of-Support OS on, I cannot help you more than that.  (They are prohibitively expensive for hobbyists here. Maybe in 3 years time...)

Here is output of lsusb

This still looks likely to be ILO related and the files you showed suggest nothing to be worried about.

They appear to be the insides of the HP AHS file. You can find some fascinating reading here: https://mark.honeychurch.org/blog/projects/ahs/ 

And this is from my DL20 Gen10,

Bus 002 Device 008: ID 0590:00d4 Omron Corp. 2JCIE-BU01

And an ML30 Gen10

Bus /dev/usb Device /dev/ugen0.3: ID 0424:2660 Microchip Technology, Inc. (formerly SMSC) Hub

As you can see, this same hub is present in all our devices.

Interestingly, trying to see if it was virtual media related caused AMSD to suicide.

Yes, I know it is ILO related and not harming my system, But wanted to know what is this device and why it is getting detected.

Also .zbb are related to AHS files, and AHS is enabled for my system.
