Hi,

Still working on my new Dell XPS15 to now get some network access, i
played with a DA200[1] adapter : USB-C to HDMI/VGA/Ethernet/USB 3.0
... When plugged at boot it trigger a KASSERT about 0 byte allocation
:

panic: kernel diagnostic assertion "requested_size > 0" failed: file "/local/src/NetBSD/src/sys/kern/subr_kmem.c", line 257

734             nifc = cdp->bNumInterface;
735             dev->ud_ifaces = kmem_alloc(nifc * sizeof(struct usbd_interface),
736                 KM_SLEEP);

738                     err = USBD_NOMEM;
739                     goto bad;

Looks like one of the devices reported 0 interfaces :(

Thanks in advance.
