OK, more resolution on the problem:
I updated the libpcap from cvs, and wireshark from svn today. Rebuilt, installed 
libpcap. Rebuilt wireshark.
I added some debug print statements to pcap-usb-linux.c . It is definitely successful in opening the "plain binary interface". It doesn't use the fast mmap 
interface.

But my understanding is that I should get the full packets.

What I see from Wireshark on the packet is
No. Time Source Destination Protocol Info 
    18 0.001973                                                USB
URB_BULK[Packet size limited during capture]
You might want to ask on tcpdump-workers@xxxxxxxxxxx; Paolo Abeni wrote the Linux USB capture code, and I don't know whether he pays more attention to the Wireshark list or the tcpdump-workers list.
