The laptop in question is relatively new, and has no extra PCI or PCIe slots, so I'll have to find a USB network adapter (I have an AX88772B, but that isn't recognized. In fact, the only thing I tried that worked was an Android phone with tethering turned on).

Hi James,

I bought one USB Ethernet adapter with that chip, and it somewhat get recognized. On boot this showed up:

 nusb/ether: a179linkup: no link
 nusb/ether: a88179 init failed:

It seems that the one I got is defective. I tested the card on a Windows machine, and Windows also says "Network cable unplugged", although I'm sure I plugged the cable in, connected to a router.

Here's the result of usbtree:

 ep15.0: 255 csp 0x00ffff vid 0x0b95 did 0x1790 'ASIX Elec. Corp.' AX88179 118ae xhci

I'll try to get another one and see if that works.

Thanks,
