Re: [Bluez-devel] Mobidick BDU33A + SCO

[Warp]

Hi, all.

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.
