I try lokalize problem and i find SIGSEGV into function hci_usb_send_frame (hci_usb.c) structure skb has invalid pointer! Some times adapter reinit or kernel going to Ooops... Next i try dont send packets only receive and problem has gone. Look like problem in write stream only. I use O_NONBLOCK streams. Any comments? Best Regards, Warp.
