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

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!
