*bump* Just to keep everyone updated on this, I have made lots of updates to both the client and DCS with much-appreciated help from Shaun, Jon, and of course BrandonW. I will be testing it tonight, hopefully, if anyone wants to help.

At this point I expect that it will be around 8pm EDT, although I am not positive yet. Smile

Thanks _player! I'm going to play a game of AoE with Sonlen now, and I'll leave my calculator connected via Chat to DUSB. I want to see if when the timeouts start to happen, the recovery code I've added will function properly.

Edit: Here's where we currently stand with Direct USB gCn, and why I'm not yet giving you guys a beta (still):

1) New features: the client will wait patiently for your calculator to be connected properly, so you can even start DCS, run Chat (or Oblit, or NetPong, or CnChess, or CnT, or whatever), then plug in your USB cable, then run the client. Or do them in a different order. It should all work

2) The CALCnet interrupt can now properly handle unplugging and replugging the cable without losing its mind

3) However, if for some reason the USB sending from the calculator times out, the OS send routine loses its mind now and kills the whole USB connection. The good thing is that timeouts are happening at all; it took tons of OS tracing with BrandonW's help to get it this far. However, it's important that I get it to behave better.

4) There's a glitch-type thing with ginormous frames being sent to the calculator after reconnect. I'm on it.

Interrupt as in join in the middle? No, I'll have to modify Obliterate to properly handle that (or rather, detect and prevent problems from it). This has to do with exactly what MadMax is seeing right now, occasional calculator lockups that can be solved with On / On / Clear.

Ah, I see, btw, it seems that an all-cap msg froze chat O-o. I would think that for the oblit problem you could just make a message that says "Sorry, there is a game running" or something of the like. Although I am sure in practice, that would be much harder >.>

Yes, it would indeed be very challenging, but I'll try to come up with something reasonable. That's a very very secondary concern after tracking down how (if!) this problem can be fixed.

Thanks a lot. Smile To keep you guys up-to-date on what's going on, I am experimenting with what bit 3,(iy+41h) does based on some tracing; setting it appears to stop the calculator from killing the USB connection when a packet send times out, but leaving it set makes DUSB freeze at other points, so I'm trying setting it right before an attempted send and resetting it directly afterwards.

Thanks, geekboy. I've managed to get one hard freeze since the changes, so I'm not happy yet, so you guys still don't have something. I fixed another glitch in the gCnClient based on my changes, so automatic reconnection is pretty nifty now, but it's still not 100%.

*bump* Making a lot of progress on this. Remaining issues are things like this happening client-side, and the calculator more or less ignoring all incoming data:

All kinds of stuff. As suggested by Jonimus, the client doesn't try to send anything to the calculator until the first frame is received from the calculator, which means that the calculator won't freeze on the homescreen anymore because of constant USB activity when you first start the client. Also, I did tons of debugging on unplugging and replugging, and it works a lot better now, both hotplugging and just plugging in normally while the program (rather than the OS) is running. Remaining glitches include the one I mentioned, and one hard-to-reproduce case where the calculator forgets it knows how to handshake USB until you hotplug once with the OS active.

Thanks, elfprince! Sadly, I've been a bit slowed down by all of the schoolwork and teaching crossing my desk, unfortunately.
