Hello guys:

I'm running Proxmox 7 which is based on Debian Bullseye (11). I connected a
TP-Link USB 3.0 network adapter on USB 2.0 ports of a IBM System x3550 M4
server.

According to what ethtool reports, there's Link detection on this network
adapter. However, I cannot make it work with a valid IP address. I set a
fixed private IP address and try to ping another host in the same network
(same ethernet switch) and there's no response.

When running tcpdump on the USB network interface, I only see a few ARP
packets trying to find the MAC address for the destination host.

Any ideas? Is this USB 3.0 adapter supposed to work when connected to a USB
2.0 port? I'd really appreciate some suggestions for troubleshooting.

Thanks in advance guys
