There are quite a few USB devices on this machine, but only 3 external ones (the Belkin Bluetooth dongle, on the side of the machine, and a hard drive and the sound card at the back):

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.

Comment 2 Joel F 2011-09-21 22:31:11 UTC

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?

Comment 3 Joel F 2011-09-21 23:30:36 UTC

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.

This was a duplicate of bug 527813, and was fixed with kernel-3.3.0-4.fc16
Please close this bug
