Can someone please simplify what is the best way to connect a mame panel that plays everything from space invaders to mortal combat 4 up to a pc without the geek talk?

IMHO this is a purely academic conversation that doesn't change any of the MAME conventional wisdom as captured in the Wiki.

Just for fun..  here's an unfiltered USBTrace history dump for banging on 7 keys simultaneously on a MiniPac:

Held them for a moment and smashed on a few times before the trial version's buffer filled up.

Edit:
and just for comparison sake, a trace where I rapidly press a single button:

I'm done arguing with you.  Leave me the heck out of this.

How can you control that number of packets sent? Encoder? Driver?

Thats just a number I decided to use when I was writing the firmware. Some devices only ACK one packet after a state change and some ACK all packets all of the time even when there is no state change. In fact the majority of devices just ACK all host requests and send the data at the specified poll rate. This just seems unnecessary to me so I stop at 5. No point in rambling on repeating yourself over and over again.....

Isn't this what HID IDLE is supposed to address?  Of course, IDLE seems to me like an overly complex solution to address such a simple problem.
