usbd_setup_ctrl_transfer: Wrong framelength

[Aman Sawrup]

Sporadically, but not very often, I see the message 
"usbd_setup_ctrl_transfer: Wrong framelength 0 != 8" while trying to 
setup transfer with umass0.  However, even when I do see the message, 
I'm still able to transfer data successfully with the device.

I'm looking for advice on whether I need to investigate this message 
further?

Thanks
Aman
