I've been using "usbmon" to dump traffic.

The tool at http://people.redhat.com/zaitcev/linux/usbmon-6.tar.gz
and not simply cat on the usbmon files in debugfs I hope.

debugfs only shows the first bytes of long transfers, but the API
used by the usbmon-6 tool shows complete traffic.

I think I start to understand. The number before "<" or "=" or ">" is
amount of bytes. For example:

ea700b40 493839847 S Bi:2:003:6 -115 8 <
We just asked for 8 bytes

ea700b40 493840818 C Bi:2:003:6 0 8 = 00060456 00000000
Here we received the 8 bytes.

f3dad540 493840838 S Bi:2:003:6 -115 13 <
We asked for 13 bytes.

f3dad540 493840923 C Bi:2:003:6 0 13 = 55534253 0a1a0000 00000000 00
The requested 13 bytes.

Now some bigger amount:

eb48d640 504977573 S Ci:2:010:0 s 80 06 0200 0000 0027 39 <
Asking for 39bytes?

eb48d640 504977936 C Ci:2:010:0 0 39 = 09022700 010100a0 64090400
0003ff02 ff000705 81031000 04070582 02000200
Only 32bytes received?

Is this the issue you meant? Am I correctly parsing that dumps?



I've quickly tried usbmon userspace tool, but not much more luck with
it. Example from this tool:

f2c19e40 6.317817 S Ci:2:013:0 s 80 06 0200 0000 0027 39 <
f2c19e40 6.318305 C Ci:2:013:0 0 39 =
    09022700 010100a0 64090400 0003ff02 ff000705 81031000 04070582 02000200
     . . ' .  . . . .  d . . .  . . . .  . . . .  . . . .  . . . .  . . . .

Maybe it requires some switch or sth... unfortunately it's not
documented at all ;/
