Re: [Bluez-users] Hci Reset Problem

[Andreas Gaufer <Andreas.Gaufer@bluecellnetworks.com>]

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=
CI])
        Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller
        Flags: bus master, medium devsel, latency 32, IRQ 12
        I/O ports at d400 [size=3D32]
        Capabilities: [80] Power Management version 2

Do you want one of these for your "nightmare chamber" marcel? ;)

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

Greetings
