Subject: Bluetooth wireless mouse very sluggish when there is moderated network activity

Hi all,

I got a Bluetooth wireless mouse identifed as,

input: Microsoft Microsoft� Wireless Notebook Presenter Mouse 8000
as /devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1.3/3-1.3:1.0/input/input12
input: USB HID v1.11 Mouse [Microsoft Microsoft� Wireless Notebook Presenter
Mouse 8000] on usb-0000:00:1d.1-1.3

Problem is when there is a moderate traffic on wireless interface (300-400k/s
down 50-60k/up on 4Mbit) mouse is really sluggish. This is when I am running
ktorrent. If I stop the torrent download/upload its fine again.

Any idea how to debug this, or why it might be happening. Btw I confirmed this
behaviour on

kernel 2.8.18.8, 2.6.22, 2.6.23 and latest GIT tree.

P.S: If it matters I am using ipw3945 driver with 2.6.18 kernel and iwl3945
with the newer ones.

Regards,
ismail

Hi Ismail,

it would be great if you'd be able to isolate what is the cause in a
little more detailed way - i.e. try a different network card in the same
machine, try a different bluetooth mouse in the same machine, try the very
same mouse and network card in a different machine, etc.

Otherwise I am afraid this is going to be just a totally wild guessing.

Thanks,
