No way.  DeviceInfo holds informations about the device 
*implementation*.  Multiple instances will share that, placing runtime 
data there is just plain wrong.

Also this is a callback from the usb device to the usb host adapter, not 
the other way around.  I'd suggest to create a USBBusOps for host 
adapter callbacks and and stick it into USBBus.

cheers,
   Gerd
