The virtual HCD on Intel and VIA EHCI controllers are UHCI. The USB-IF insisted on only one implementation of EHCI but creates 4 virtual hcd to cover USB1.1 support.

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). ![]() Bulk - Midi ( 'send my data when you can' ).USB transfers can be of the type control, isochronous, interrupt, or bulk.
