This is a good one to start with as it is seen literally hundreds of 
times in the trace.

20    in down    n/a    3.195    VENDOR_ENDPOINT    -   
URB Header (length: 80)
SequenceNumber: 20
Function: 0019 (VENDOR_ENDPOINT)
PipeHandle: 00000000

SetupPacket:
0000: 00 81 82 00 00 00 00 00
bmRequestType: 00
  DIR: Host-To-Device
  TYPE: Standard
  RECIPIENT: Device
bRequest: 81 
  unknown!


No TransferBuffer


If I had to guess, this packet is acting something like a "get next" 
type of function.  I can make the entire SnoopyPro dump file available 
if that would help.
