1. if I need to capture all the data host capture from bus, usb mon

c. feed the binary file to wireshark.
With usbmon loaded, wireshark can capture from usbmon directly. Depending
on
your distro, you may need to load usbmon manually:
modprobe usbmon
forget to mentioned, my platform is arm embedded system.
And it seems I have to get binary from my target board then feed it to
wireshark on my pc, right?
if so, how could I dump the binary from embedded target board?
Use tcpdump:
tcpdump -i usbmon1 -w out.dump
It is embarrassing that busybox on the target don't have "tcpdump" :-)
Is there any other way to reach the same goal?
If it were me, I'd compile tcpdump and libpcap for your target, or find
a userspace that has them pre-built, like Angstrom or buildroot.
