Re: New Broadcom chip in W510

[Lu Ran <hephooey@gmail.com>]

Hi,

I have made some progress today, appearently 28 is ENOSPC, meaning the usb 
host controller does not have enough bandwidth for the device. Indeed when I 
unplug my usb mouse I can have playback (mic is still missing with ENOSPC). Is 
there a way to reduce the package size from btusb, the mouse is the only 
device I can remove, there are a internal camera and figure print reader always 
connected.
