and base the scheduler on that and other factors. One needs to calculate the USB bandwidth etc. It all gets difficult as the device making use of the isoc transfer may be at any point on the device tree. Setting up the isoc transfer pipe might differ on those two and the driver code might be different as well.įor isoc transfer there needs to be a scheduler that makes sure no isoc transfers are dropped (in or out) and that they happen at the right time. One is just the normal isoc transfer and the other is realtime implementation of isoc transfer. There seems to be 2 types of isoc transfers that can be used by Poseidon. IsoChronous code is already in place in poseidon.library BUT transfers are not queued to be later rerouted in the host driver code (needs to be written for each host OCHI UCHI EHCI etc).
Isochronous - USBAudio, Webcams, etc (wip).USB transfers can be of the type control, isochronous, interrupt, or bulk.

I don't necessarily blame Wacom for having difficulty squashing bugs. I'll try this new 6.3.19-6 release, but I have little expectations that it will actually be bug-free - more a matter of if I can live with the bugs it (probably) has.
I'm still using Driver 6.3.15-3 because thus far, it's the last release WITHOUT major bugs. I suppose OSX may have made the difference, when they started REQUIRING reboots upon driver update (didn't need that before). Horrible development and unlike Wacom in the 90s or 2000s. Eventually landing on a driver that seems fairly stable. make 4 more versions, all introducing NEW bugs over the next few months. This seems like standard practice for the folks at Wacom now. It removed ALL functionality of modifier keys (Command, Option, Control) in all apps which weren't "Wacom-aware".
WacomTablet_6.3.19-6.dmg was release on Dec 23rd.
