Uhm, class3 is just Human Interface Device class, without
specifics. You could just try to bind these to the usb_ac/_as
as a wild guess via /etc/driver_aliases:

usb_ac "usbif1852,8005.1.config1.0" or "usbif1852,8005.config1.0"
usb_as "usbif1852,class3"

then plug and pray....But devices proprely designed for the USB
audio class would give class1.1 and 1.2, so I don't expect that
that will work. Usually, you have to bind it to the ugen driver,
which gives you a raw interface, for which you then could
implement a "userland" driver, but I don't think it's worth the
effort given the low prices of such devices. I had the same
experience with a Logitech Cam (which usually have their own
propriary drivers), and I just dumped that for a cheaper Trust Cam
with a standard USB Video Class interface, which is just plug and
play in Openindiana and works.
