NSLU2, USB 1.1 Sound, error -28, CONFIG_USB_EHCI_TT_NEWSCHED

[debian-lists@knackich.de]

Hi,

I have recently upgraded my NSLU2 from DebianSlug to the "pure" Debian 
solution. I had problems with playing sound. I would get 
an »error -28: not enough bandwidth« in dmesg and an error from ALSA. 
I have a cheap USB 1.1 sound adapter ("C-Media USB Headphone Set") 
and an X10 remote control on an USB 2.0 powered hub. When I removed 
the remote control the sound worked again without problems. I have 
now recompiled an own kernel with CONFIG_USB_EHCI_TT_NEWSCHED enabled 
and the issue is gone.

Would it make sense and would it be possible to enable 
CONFIG_USB_EHCI_TT_NEWSCHED as a default? Or should I compile my own 
kernels in the future?

Thanks,
Hermann
