changed since then. Because of that we won't fix this issue however if
this behavior repeats on a modern version please fill a bug report

Title:
  Bluetooth mouse lag on Dell Notebooks

Status in bluez package in Ubuntu:
  Invalid

Bug description:
  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 1520 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.
  The Mouse works fine under Windows XP and 7, regardless of the points above.
  I'm using Oneiric 64bit, but this happened also on Natty x86 and i think on Maverick x86 as well.
