[Bug 40623] [dapper] Cannot play sound on USB device through a HUB

[DaTa]

Public bug reported:

Affects: linux-source-2.6.15 linux-image-2.6.15-20-386 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
I recently upgraded vom breezy badger to dapper drake.

My Logitech USB Headset wasn't working anymore:

[1]> cat /vmlinuz > /dev/dsp1 
cat: write error: Broken pipe

while

[1]> cat /vmlinuz > /dev/dsp

worked fine.

Apr 21 20:33:59 localhost kernel: [4362501.009000] cannot submit datapipe for urb 0, error -38: enable CONFIG_USB_EHCI_SPLIT_ISO to play through a hub

And yes, my headset is plugged into an external hub. So I plugged it
into the root hub and now it works. But it would be nice to compile the
kernel with the above option for the final release.
