I have no idea why I wrote 8.3-RC1 here. It should be 9.1-RC1

I didn't know webcamd supports that kind of devices; I thought
it only supports video/audio stuff.

Anyway, here's what I get with webcamd-3.7.0.1:

    # usbconf | grep WALTOP
    ugen3.2: <Slim Tablet WALTOP International Corp.> at usbus3,
    cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

    # webcamd -d 3.2
    webcamd: Cannot find USB device

The same thing happens if I use libusb_detach_kernel_driver(3)
to detach ums(4) from the tablet prior to trying webcamd.
