Post Body

Is anyone else running NixOS and has any pointers for getting the ethernet expansion card to work?

lsusb shows the card:

Bus 004 Device 002: ID 0bda:8156 Realtek Semiconductor Corp. USB 10/100/1G/2.5G LAN

But ip a shows no carrier:

enp0s13f0u4c2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 9c:bf:0d:00:0e:88 brd ff:ff:ff:ff:ff:ff

Does anyone have an idea? I'm connected via Wifi, but that can be a bit unstable in my flat unfortunately. The cable is working, I tried it on my old Thinkpad, and I even tried the expansion card on my husband's Macbook and it did work there.

Edit: I figured it out: The usb autosuspend was too aggressive. Setting up a udev rule (ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="0bda", ATTR{idProduct}=="8156", ATTR{power/autosuspend}="20") or setting the corresponding kernel parameter (usbcore.autosuspend=20) fixed it
