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
