can't change HCI and LMP version on Cellink BTA-6030

Hello!
Few days ago I've got Cellink BTA-6030 Bluetooth dongle but
have a 
problem installing it on my Debian box for which it was
bought.
It works slower than my previous LinkSys BT100 V1.1
Bluetooth, on other 
end I've got Canyon V1.2

After some reading I've checked how device is identify
itself and spot 
that from remote WinXP notebook it's reported that LMP
feature - unknown 
and LMP Version is simply blank. I've recompiled BlueZ 3.2
with bccmd 
enabled and tried perform these steps:
------------------------------------------------------------
----------------------------------
# bccmd psget version
The HCI and LMP version reported locally: 0x0101 (257)
# bccmd psset version 0x0303
# bccmd psget remver
Can't execute command: No such device or address (6)
# bccmd psset remver 0x0003
# bccmd warmreset
# bccmd psget version
The HCI and LMP version reported locally: 0x0101 (257)
# bccmd psget remver
Can't execute command: No such device or address (6)
------------------------------------------------------------
----------------------------------

But as you can see it doesn't let me to reset LMP version.
From other 
side if plug this device in WinXP notebook it's reported as
v2.0 device.

Any ideas how this could be fixed and maybe I'm doing
something wrong?

Thank you!

the bccmd defaults for the used stores are chosen the way
that you can't
mess up your dongle. This means that you have explicitly
choose a store
that is persistent. However the best is to use psread and
then simply
use psclr to remove the bogus PS key.

In general if you don't know what you are doing, then
don't touch the PS
keys.

Regards

Marcel

Hi Marcel! First of all let me thank you for making great
peace of 
software, I'd be lost without it!

yeah I know this rule, but I'd like to learn this, and
correct the way 
dongle behave so I can utilize it at full power. So maybe
you can 
provide me with more information on this issue, I'd like to
take a risk 
and wouldn't blame you if dongle become not useable.

not sure which key to remove as I've run psread before and
didn't find 
key representing bluetooth protocol for remote PC.

Maybe you can point me on where to look for information so I
can 
understand how it works or maybe I can post readout of
psread and you 
advice me what needs to be corrected?

Thank you!
