Same device address!!

I bought 2 Bluetooth adaptors

IVT BT-100 USB 2.0 Dongle

I put one in the workstation , havent tried it on Gentoo yet but in windows I get the address 22:22:22:22:22:22 , then I put the other dongle I bought on the Debian box and it also gets the 22:22:22:22:22:22 address

hciconfig hci0

TX bytes:455 acl:0 sco:0 commands:25 errors:0

If I scan for my devices it says <my other comp name> 22:22:22:22:22:22
but they both use 22:22:22:22:22:22 and I think there might be some problems there...
Any way to set a new one? Or make it switch to a new one?

Is this a theoretical problem or are you having trouble getting the Bluetooth devices to work? Plug your Bluetooth devices into the computer and try to use them. If they work then you are okay.

Hardware drivers are being developed so fast with new techniques that it doesn't pay to look for problems if the hardware works. I remember when I first heard about IRQ sharing between cards. I thought it was crazy. I had built many WinTel computers where tracking and keeping IRQs separate was the most important thing when you were building a computer. There were card jumpers and configuration software to set IRQs on cards. It was a lot of trouble. When IRQ sharing was invented it didn't make sense to me but it works.

Don't look for problems that haven't impacted the performance of the computer.

They work on my laptop and my workstation
but not on my quite on the server

Im trying to ping my devices.
I can ping my cellphone from the server
but I cant ping workstation or laptop cuz they use the address 22:22:22:22:22:22

And I think this is what makes me unable to setup my NAP/GN.

Code:

One big problem is sending stuff to my laptop or server from my cellphone...
When it tries to connect to 22:22:22:22:22:22 I might end up with a connection to laptop or the server if both got bluetooth enabled since both are on the same address...

mostly times I cant send anything at all.. so I have to turn off one bluetooth
