[Bluez-users] USB - Stable connection

["P. Elias" <p_ilias@hotmail.com>]

Hi,

I'm not sure if this is a bluez related issue but it might help some people 
who have l2cap connection problems.

I'm running kernel 2.4.22 on both machines (1 desktop, 1 laptop) without any 
patch installed. USB and Bluetooth support compiled as modules.

I had troubles getting a stable l2cap link between them. The connection was 
breaking after some packet transmission, even by surfing the web. The cause 
of the problem was the UHCI module (laptop side) which was crashing 
unexpectedly after removing it with the bluetooth dongle plugged. I tried to 
load the USB-UHCI instead and the link works fine now. I tested it overnight 
downloading 1.5 GB at 75Kbps stable speed without any interrupt.

Have a look at my loaded modules:

usb-uhci             23500   0  (unused)
hci_usb              8088     1
usbcore              62624   1  [usb-uhci hci_usb]
bnep                  10324   1
crc32                  2880    0  [bnep]
l2cap                 16876   2  [bnep]
bluez                 32196   1  [hci_usb bnep l2cap]

I hope this will help you guys..
Greetings
