Hi to everyone, (for Gustavo... I sent you a message abput the same argument... sorry for the duplication)

I hope there are new about this bug

I am using a board (VDX6318D) by Icop Technologies with their linux 2.6.34.1-vortex86-sg.
The dongle I use is "Sena Parani UD100" (that uses Cambridge Silicon Radio).

On board there are 4 USB (2 for each internal hubs), one of this USB are used by internal sound device. I install bluecove-gpl-2.1.0 and bluecove-2.1.0. When I plug 2 of UD100 they works fine, I cannot use 3 dongle togheter because the third does'nt work.

Using hciconfig I have this message:

hci0: Type: BR/EDR Bus: USB

 TX bytes:358 acl:0 sco:0 commands:26 errors:0

You can see that the hci0 is DOWN, without address and with TX errors, hci2 is fine but with 2 errors (after this it seems work always fine) and hci3 is fine.

I have to use three dongle because I need perfomance to push bluetooth message to many mobile phone and to listen for receive message by other many mobile phones. In future I want use every 4 usb for dongles (I can disable sound device).

I excanged the dongle plugged many times and using other dongle UD100 and also other device with Cambridge Silicon Radio, the problem is the last dongle I plug in a pair of USB of the some internal hub (the dongle in the other hub is always alone, in the example of hciconfig it is hci3). I use other identical board (VDX6318) and I exchange cable, disk on chip, I'am sure I don't have problem with hw. The incredible things is that i plug other dongle "not with Cambridge Silicon Radio" and they works fine with the other 2 UD100.

Thanks in advance
