There's not much we can do about that, since the card wants to reserve enough bandwidth to handle audio output and other devices prevent that from happening.
I get this error with an Edirol UA-25ex, which has been working before in full-duplex mode on an USB2.0 port. But since I upgraded to F15 and later I get this error even if I unplug all the other usb-devices. I googled and found the experimental CONFIG_USB_BANDWIDTH. I will try compile a kernel with that enabled to see if it affects the problem. Q: Is there a way to display the USB bandwidth allocations?
Or wait, is it my internal devices (Root hubs) on the bus that is preventing my USB v1.1 from getting enough bandwidth from a USB 2.0 port? I should also add that it only happens in the advanced mode of the UA-25ex. It should be able to work in full duplex even then except on 96kHz sampling.
