[Bluez-users] USB/Bluetooth dongle doesn't work in hub

[Bluez-users] USB/Bluetooth dongle doesn't work in hub

[Scott W Gifford]

Hello,

I'm trying to connect a USB/Bluetooth dongle to my laptop running
Fedora Core 2 with a Linux 2.6.8-1.521 kernel, and these bluez RPMs
installed:

    bluez-bluefw-1.0-2, bluez-libs-2.5-2.1, bluez-libs-devel-2.5-2.1,
    bluez-pin-0.23-1, bluez-utils-2.4-3, bluez-sdp-devel-1.5-2.1,
    bluez-hcidump-1.5-4, bluez-sdp-1.5-2.1, bluez-pan-1.1-4

I've got both a Belkin F8T001 version 2 dongle, and an AmbiCom
BT2000.C-USB dongle.  Both devices work great when I plug them
directly into the laptop, but fail when I connect them via a hub,
logging something like this:

    Nov  8 18:29:24 localhost kernel: hci_usb_intr_rx_submit: hci0 intr rx submit failed urb 1f48cf94 err -28
    Nov  8 18:29:24 localhost hcid[23855]: Can't init device hci0. Input/output error(5)

I get the same effect plugging in to the hub on my base station, my
keyboard, or a Belkin hub I just purchased.

I'd like to get this working for two reasons.  First, the USB ports on
my laptop aren't available when I'm in my docking station.  Second,
for the project I'm working on I'd like to connect several Bluetooth
adapters to my machine over a distance of 20 meters or so, which will
require hubs.

I've appended full logs of what happens on a working direct connection
and a failed connection through a hub, with the Belkin adapter; the
results with the AmbiCom are similar.

Any advice on getting this working?

Thanks!

----ScottG.

This looks like an USB problem to me. Update your kernel to the latest
Bitkeeper snapshot and try again.

What kind of dongles are these (hciconfig -a)?

Ah, OK; they're the ones supplied by Fedora.  I'll try newer ones from
the Bluez Web site.

I removed all of Fedora's bluez stuff, and installed:

    bluez-firmware-1.0.tar.gz, bluez-hcidump-1.12.tar.gz,
    bluez-libs-2.10.tar.gz, bluez-utils-2.10.tar.gz

I downloaded a new kernel with:

    bk clone http://linux-mh.bkbits.net/bluetooth-2.6

, compiled and booted, and I still am getting roughly the same error:

    Nov  9 00:36:06 localhost usb.agent[4258]: Setup hci_usb for USB product 50d/81/828

    Nov  9 00:36:07 localhost usb.agent[4258]: Setup 0x00 0x00 for USB product 50d/81/828

As before, they work fine when plugged directly into the laptop.

Thanks!

go ahead and report this problem to the USB mailing list, because it is
not a Bluetooth problem and I don't know why this fails.

I didn't get an answer on the USB mailing list, but I saw another
related answer that seemed to help.  Apparently using certain types of
transfers on a high-speed hub with a low-speed device is still
unsupported:

  http://www.linux-usb.org/usb2.html

    In terms of functionality, the latest driver:

    [...]

    * Has partial support for split transactions (full and low speed
      transfers) through USB 2.0 hubs:

    [...]

      o You can't (yet) use full speed isochronous transfers through
        USB 2.0 hubs. (At least without an experimental patch.)  That
        means: don't hook up USB 1.1 webcams, speakers, etc. to high
        speed buses, they'll enumerate but you won't be able to use
        them otherwise. Eventually of course a dozen USB 1.1 webcams
        will easily coexist at full data rate on a single USB 2.0 bus,
        using USB 2.0 hubs.

The "ehci-hcd" module provides support for high-speed USB 2.0.
Removing it with rmmod makes everything run as low-speed USB 1.x, and
that seems to solve the problem.

I tested with the dongles I have: D-link DBT-120, Belkin F8T001,
AmbiCom BT2000, and IOGear GBU211.  I tested plugged directly in,
plugged into a hub connected directly, and plugged into a hub
connected to a hub connected to a hub connected directly.
