that was very helpful.

I've got a question regarding ISO transfer. If the firmware is not

how can I check that in the driver? I'm working on a solution for my

so that a couple

Hi all,
I'm the maintainter of the the USBDUX* devices.
They are USB 2.0 high speed devices. I use urb-interval to control the
sampling rate of these devices. That works fine with the ehci driver.
When I use the xhci driver it seems to be interpreting the urb-interval
in a different way
update the firmware for xhci and
test it without causing havoc for those using the drivers just now.
In that way USB 2.0 is untouched and I can write the xhci support which
doesn't work at all at the moment so can only get better.

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?
