Try adding a macro for the correct device ID to
/usr/src/sys/dev/usb/usbdevs. In this file it is listed as GUILLEMOT
instead of Hercules, though.

You should be able to see the device-id with 'usbdevs -v'. You're
looking for the first hexadecimal number (preceded by 0x). The second
one is the vendor, and should be 0x06F8.

Look for this in /usr/src/sys/dev/usb/usbdevs: 
product GUILLEMOT HWGUSB254     0xe000  HWGUSB2-54 WLAN

Then add

product GUILLEMOT HWGUSB254V2     0x????  HWGUSB2-54-V2 WLAN

Replace the ???? by the correct device ID. :-)

Add it to the usb_devno ural_devs array in
/usr/src/sys/dev/usb/if_ural.c, and rebuild your kernel.

Look for this in /usr/src/sys/dev/usb/if_ural.c

Then add

Rebuild and install your kernel, reboot and try again.
