Re: [Linux-usb-users] Next step in reverse engineering USB robot

[Douglas S. Blank]

No one knows how to generate the following URBs using libusb, or any 
other protocol? I suspect it can be done with a call to 
usb_control_msg(), but I have no idea how.

This is a dump from usbsnoopy under Windows:

Maybe I'm emailing the wrong groups? Any help would be appreciated! 
Thanks in advance!
