Hi all,
is that right that setting urb->interval does not work for the xhci
driver? Seems so that the driver (in my case the usbduxsigma.c) needs to
request the xhci_interval and then has to live with that frame rate so
essentially 125us? Is that right?
/Bernd
xhci-ring.c: (I've added a couple of debug messages to it)
if (xhci_interval != ep_interval) {
dev_err(&urb->dev->dev,
"Driver uses different interval (%d microframe%s) than xHCI
(%d microframe%s)\n",
ep_interval, ep_interval == 1 ? "" : "s",
xhci_interval, xhci_interval == 1 ? "" : "s");
urb->interval = xhci_interval;
/* Convert back to frames for LS/FS devices */
if (urb->dev->speed == USB_SPEED_LOW ||
urb->dev->speed == USB_SPEED_FULL)
urb->interval /= 8;
}
return xhci_queue_bulk_tx(xhci, mem_flags, urb, slot_id, ep_index);
