Hello,
i've installed the ubt driver from the subversion repo at turbocat.com,
and now my BT dongle seems to work, but with some strange side effects.
For example i can connect to my GPS receiver properly, and get output
(rfcomm_spp -a gps -c 1)
but when i'm trying to issue a inquiry command with discoverable devices nearby
i get :
vaio# hccontrol -n ubt0hci Inquiry
ubt0:ubt_intr_read_complete:883: Invalid HCI event frame size, length=15,
pktlen=17
and nothing is discovered.
Also when exiting from rfcomm_spp with ctrl-c i get this :
ng_btsocket_rfcomm_receive_uih: Got UIH for dlci=2 in invalid state=5,
flags=0x3
This is FreeBSD 6.1-STABLE running on Sony VAIO PCG-U3.
P.S.: I have also working ural(4) device with the new usb stack.
It seems more reliable, because before often after a few insers/removals
i was getting instant reboots. The only thing is the many "ural_newstate:
cannot call usb_rem_task...."
messages.
P.S.2: Also i seem to get strange output from usbdevs with the new usb stack.
I get "I/O Error" message for every possible USB address. I think the problem
is that the usb subsystem returns EINVAL where it can return ENXIO to inform
the caller that there is no such device.
I tried this patch that seems to work ok for me, but i'm not sure if it is
completely correct.
