[Bug 894274] [NEW] Bluetooth mouse lag on Dell Notebooks

[entonjackson]

Public bug reported:

My Microsoft Notebook Mouse 5000 (which is a Bluetooth Mouse) is lagging
a lot in 2 cases:

-On heavy WiFi traffic
-More Bluetooth Devices are connected, e.g. a phone.

This problem occurs on a Dell Vostro 1510 with a bluetooth dongle:
ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

And also on the Dell Precision M4400 with BT device:
ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)

While BT Mouse lags, touchpad works normally.

Actually, i don't know where the problem comes from. but i think it's bluez.
to me, this bug is critical, because very annoying.

I hope it gets fixed soon, because new users to ubuntu could be
frightend off because of bugs like this.

I'm using Oneiric 64bit, but this happened also on Natty x86 and i think
on Maverick x86 as well.
