[sane-devel] Setup Packet Question

I feel like I understand almost all of what is happening in this log:

However, I don't understand any of the Setup Packets with the 
bmRequestType of 0x21. They all appear as the URB is "coming back!" But 
0x21 is a host-to-device transfer of type class with the recipient being 
the interface. Is there something about the URBs "going down" and 
"coming back" that I don't understand?

Thank You,

Tabor Kelly
