I currently have a Zaurus connected to my NetBSD 4.0_BETA2 (december 9)
machine over USB. As expected, the cdce driver automatically sees the

cdce0 at uhub2 port 1 configuration 1 interface 0
cdce0: Sharp SL-C3200, rev 2.00/0.00, addr 2
cdce0: faking address
cdce0: address 2a:71:7b:0a:00:00

which looks normal to me. When trying to ping the two devices however,
nothing gets through. The following error message occurs over and over:

where is the zaurus. tcpdump tells me:

17:19:19.350897 IP > icmp 64: echo request seq 256

where is the NetBSD host. If I get it correctly, there is a
problem on the NetBSD side, which fails to register the Zaurus' MAC
address. I'll try to fix this on my side as well, and please tell me if
you need anything more.
