Endpoints

Hey,

I don't mean to stir up a hornet's nest here... but has anyone noticed that 
the NetMD has several endpoints? Two bulk endpoints, one for each direction?
My N1 has;

$ info /dev/bus/usb/0/0
[Device]
Class .................. 0
Subclass ............... 0
Protocol ............... 0
Vendor ID .............. 0x054c
Product ID ............. 0x0075
Version ................ 0x0100

Product String ......... "Net MD Walkman"
Serial Number .......... ""
  [Configuration 0]
    [Interface 0]
    Class .............. 255
    Subclass ........... 0
    Protocol ........... 0
      [Endpoint 0]
      MaxPacketSize .... 64
      Interval ......... 0
      Type ............. Bulk
      Direction ........ Input
      [Endpoint 1]
      MaxPacketSize .... 64
      Interval ......... 0
      Type ............. Bulk
      Direction ........ Output
      [Endpoint 2]
      MaxPacketSize .... 16
      Interval ......... 0
      Type ............. Interrupt
      Direction ........ Input 

Just curious if this means anything, really.
