Hi,
I try to setup openobex on my linux, but each time I send out obex
connect request, instead of getting a connect response, the device will
be reset, HCIDUMP is like below:

The system I have is Linux 2.6.9-34, bluez-lib-2.25 and bluez-util-2.25,
bluez-hcidump-1.30, and openobex-1.0.1 version. I don't know who send
this reset, and why.
Thanks.

the reset is really strange. It comes from our side. What does
"hciconfig -a" say about your dongle.

Hi,
I guess I'm approaching the same or at least a related problem. I don't
feel like getting close the root of the problem yet but maybe the
attached output helps marcel or someone else to see clearer.
I can't pretend that the reset in the attached log is not beeing sent from a
user-application but i felt like the oops is worth posting.
Kernel used is 2.6.8.1 but i know that the thing happens also with 2.6.17.6.
Hardware used:
hci1: Type: USB
BD Address: 00:02:5B:00:BF:66 ACL MTU: 384:8 SCO MTU: 64:8

I don't expect any feedback on this, I'll post in this thread if I find anything..
Greetings
Andy

Hi,
I have evidence that this may be caused by the usb-part of these devices
(B-Speech, Model: DataSpeed). Other devices (Level One, MDU-0025USB)
don't show this problem on first sight. Both use BlueCore04, HCI 19.2.
The tests where run using USB 2 Hub with 4 bt-devices pumping obex
traffic at max possible speed and this Host Controller:
00:11.2 USB Controller: VIA Technologies, Inc. USB (rev 1e) (prog-if 00 [UH=

Lan, can you check your dmesg/syslog for usb related problems please.

Hi,
further tests proofed that the problem described here are caused by
the USB-hub used. It seems to be unable to handle the load and just
breaks down. The same operations are working on other (higher quality) hubs.
Watch out for lines like
usb 1-1: USB disconnect, address 29
in syslog and/or dmesg to check if your problem is similar. Make sure
not to mess with real physical disconnects which produce the same log
output.
I guess the HCI_RESET is issued by bluez after the device comes back on.
Greetings
Andy

does this also happens if you load the hci_usb driver with "isoc=0" to
disable all ISOC transfers.

This could be the case.

Confuses me a bit... my kernel (2.6.8.1) says: kernel: hci_usb: Unknown parameter `isoc'
my modinfo -p hci_usb says: "nothing".

this is a fairly old kernel. This also means that this can be a bug in
the USB subsystem. Move to the latest 2.6.17 or even 2.6.18-rc3 kernel.
