[Bug 894274] Re: Bluetooth mouse lag on Dell Notebooks

[entonjackson]

** Description changed:

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

+ The Mouse works fine under Windows XP and 7, regardless of the points above.
