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.
