Erm, if I understand you right, how about a D-Link DU-128+ TA?
Here are some hints:
bLength=18 bDescriptorType=1 bcdUSB=1.10 bDeviceClass=255 bDeviceSubClass=0
^^^^^^^^^^^^^^^^
bNumEndpoints=0 bInterfaceClass=255 bInterfaceSubClass=0
^^^^^^^^^^^^^^^^^^^
bNumEndpoints=5 bInterfaceClass=255 bInterfaceSubClass=0
^^^^^^^^^^^^^^^^^^^
Also, src/sys/dev/usb/usb.h .
If I'm not understanding you right, then sorry...

Also `usbgen' is useful too. Although I'm not sure that as it exists,
it's doing everything it should, as I seem to have some errors pulling
some strings out of some devices.
getstring 1 failed (error=5)
getstring 2 failed (error=5)
I wonder if the recent NetBSD language delta has anything to do with
this; as recent NetBSD can retrieve the vendor of my sound card while
the old FreeBSD code I'm still running can't...
(usbctl is the tool I was thinking of -- I happened to have an old
binary compiled for an old kernel with a different ioctl() to query
the device.) Also of interest is `testlibusb' in the devel/libusb port.
They pretty much present the same info in different ways.
