I tried an Edimax USB Ethernet adapter on my -current system. It attaches as ugen1 but not as axen0:
ugen1 at uhub3 port 2 "ASIX Elec. Corp. AX88179" rev 2.10/1.00 addr 3 According to axen(4) this device should be supported. But config does not find axen. Is this becaus usb is handled differently or is the driver not enabled yet? $ config -ef /bsd OpenBSD 5.5-current (GENERIC.MP) #25: Tue Mar 25 15:40:38 MDT 2014 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP Enter 'help' for information ukc> find axen ukc> quit Device details (lsusb) and dmesg: Bus 001 Device 003: ID 0b95:1790 ASIX Electronics Corp.
