[Bluez-users] HCI Stops responding

[Bluez-users] HCI Stops responding

[mr]

Hi,



I am using Slackware 10 with bluetooth support compiled as modules and bluez-libs-2.10 & bluez-utils-2.10. My box is an Athlon AMD K7 600MHz and the motherboard is Gigabyte 7IXE.



I can;t get bluez to work properly. After some packets transmission the link breaks down and I have to unplug the dongle and plug it back again. It happened once to load the uhci (or usb-uhci) module and the PAN worked fine. However it is impossible to load these modules in the new distribution of Slackware, so I have to use usb-ohci instead.



I can't find out the source of the problem..

Please help





regards

Elias

I'm using 2.4.27 with bluetooth support compiled as modules. The hci_usb is compiled with SCO support.



The lsmod gives:



bnep                    8500   1

l2cap                  15952   2  [bnep]

hci_usb                 8504   1

bluez                  29092   3  [sco bnep l2cap hci_usb]

usbcore                61452   1  [usb-ohci hci_usb]

fealnx                 10288   2

mii                     2368   0  [fealnx]

crc32                   2848   0  [bnep fealnx]



I have tried bluez-libs & utils 2.7 and 2.10 (currently) as well.

Elias

don't try other packet types. Leave them all on. The link manager will
use the right one. What kernel do you use? Is the hci_usb driver
compiled with SCO support?
