I use socket bluetooth CF cards and web browse over GPRS quite often. I've never seen this issue on any of my devices. I'll be getting a C3200 soon. I can test out a USB bluetooth dongle and see CPU usage.

For what it's worth, here's a screenshot of CPU usage as I plug in my Kensington EDR Bluetooth dongle.
First 2 screenshots are for the Kensington EDR Bluetooth dongle. It maxes the application CPU, which then drops. Then maxes the system CPU and stays maxed. I have a Socket Bluetooth (rev K) CF card also. The 3rd screenshot shows the CPU in sysinfo as I plug in the Socket Bluetooth card. EDIT: The CPU usage for the Socket card is quite a lot lower than the above USB dongle. This post has been edited by Jon_J: Jan 17 2007, 10:18 AM

Hi !
I use everyday an Ovislink BT usb dongle, and I have no CPU usage problems. The CPU is at 100% during 20 seconds when I plug the dongle but it's because of the buggy hotplug scripts (I've done a quick hack to reduce this down to 5 seconds). Moreover the dongle current consomption is very low. Cheers, Ludo. |

on shot 2 the cpu usage dropped off when i was doing something else otherwise it would be the same as shot 1.
could it be a bluez problem?
