Hi,
Series looks good, only remark I have is that with 6/6
you're not passing in interface information, that really is
not a good idea, since for almost all devices if you want to filter
on usb classes (which you usually do) the interesting bits are in
the interface info.
Now it might be that when usbclerk runs you don't know the configuration,
but most devices have only 1 config, so for those that is not a problem :)
For multi config devices, you can do as you do now and not pass in any
interface info, or simply pass in the interface info for the currently
active config. Note that what happens on the host side is that the filter
gets run for the current config, and if the config changes it gets re-run
with the new interface info.
Regards,
Hans
