To follow up further:

This is the OpenBSD (3.9/i386) dmesg for the device:
ugen0 at uhub0 port 1
ugen0: WK-668 USB NIC HenTong Tech CO., LTD, rev 1.10/1.01, addr 2
(The GENERIC kernel uses the ugen driver for unknown USB devices. Unfortunately
ugen is not an Ethernet driver so i can't run ifconfig on ugen0)

This is the Linux dmesg for the device (showing vendor/product ID):
usb.c: USB device 2 (vend/prod 0xa46/0x668) is not claimed by any active
driver.
(Linux is handy for getting info like that.)

I have seen the chip & it is a DAVICOM DM9601E.

The kernel driver source (if_udav.c) has a disabled generic driver that uses
0x9601 as prod ID:
#if 0
/* DAVICOM DM9601 Generic? */
/* XXX: The following ids was obtained from the data sheet. */
{{ 0x0a46, 0x9601 }, 0},
#endif

I will try adding this below it:
#if 1
/* HenTong WK-668 */
{{ 0x0a46, 0x0668 }, 0},
#endif

If this ugly works, I may consider making a proper kernel source contribution,
although I wouldn't know how...
