Hi Peter,

What is the current status of btusb auto suspend? btusb not having this
feature basically renders BT useless on mobile devices.

I found some rfc patches and discussion over on linux-pm/-usb but
couldn't find a clear consensus.

I think none of the patches apply anymore. So they have to be redone
against the latest -rc4 kernel or bluetooth-testing.git.

I am porting forward to Linus' tree. I thought they'd safely wait for
the next merge window.

We had some battles with broken Bluetooth hardware that requires to keep
the interrupt and bulk URBs in fly, because otherwise the firmware
inside the controller can't sync them up and times out. These are all
fixed now, but nobody has looked at the auto suspend stuff. Feel free to

It will have to be changed to work with those buggy devices.
Do you have a pointer to a page describing the problem in detail?

pick Oliver's patches up and send them for review. If you do so, please
use linux-bluetooth@vger.kernel.org since I do miss posting on LKML from
time to time.

Peter, are you willing to test?
