Need help adding USB 2.5 NIC adapter

Hi guys!
I am a complete OMV noob. My server was setup by someone no longer available to help. It was created to store Photo work backups and host my Emby Server.
I want to update it to a 2.5 NIC using a USB adapter but cannot figure out how to make it works as is not plug and play.
I got my new switch ready and my HTPC is already doing 2.5 so only need the server to take advantage of the faster speeds.
Any help will be appreciated.
Thanks!
 
Uhh, a usb ethernet dongle?

Support for those are pretty bad on Linux, not because the eth chip isn't supported, but because they use a stupid mass storage device usb mode and to switch the device mode requires specific interaction with the hardware (which the driver you install in windows usually does).

I could swear someone made a list of working adapters, but I can't find it right now.
 
What's it say with lsusb? Once we know the chipset, its possible to hunt down the kernel modules (drivers) for it.

doesnt seem to show up at all. I tried different ports



root@openmediavault:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

You're in a virtual machine? It won't get a usb device unless you pass it through the host. And I don't know that it makes sense to pass through a usb nic. Probably better to have the host use the usb nic and use virtio-net to pass through networking. I'd consider passing through a pcie nic if you've got pci pass through working, but that's not always simple to get going either.

Ok I see this is going to be complicated.
Thanks for the help though :)
 
Its not really complicated. Either host has it & then have the VM use the host's connection or give full access to the VM.

Either way, we might be able to figure it out. Is the host Windows or Linux & what hypervisor are you using? Taking all of this in steps might lead to success.
 
I've been using a generic Realtek RTL8156 based 2.5GbE USB NIC on OMV 6 and now 7 without issue for years. I made sure the kernel is more up-to-date (on OMV there's a Proxmox kernel plugin that allows choosing a different, more up-to-date kernel to use seamlessly).

I know under Windows it presents itself as a mass storage device with the drivers on it (at least until drivers are installed) but never noticed/experienced this under Linux.

(RTL8157 5GbE USB NICs on the other hand are a royal PITA though)
 
I am using ChatGPT to try get this done :D
So far at least I am getting closer ...looks like I need to shutdown the VM so I can add the NIC next
