[Bluez-devel] Running bluez on vmware?

[Frederic Dalleau <frederic.dalleau@access-company.com>]

Hi All,


A coworker is now working on running bluez over vmware. As a part of 
that, he is trying to get a Bluetooth dongle to work (the same dongle 
we've been using three weeks ago).

For far there seem to be a strange "hang" problem of hcid. It seems it 
does not complete the initialization of the device.

I hope some of you might be able to provide some pointers on this issue, 
so I'll present you what he's been able to come up so far.

Setup:

- BT dongle is connected through a USB 1.1 HUB. This is because vmware 
supports only USB1.1 devices (more info is here: 
http://kb.vmware.com/KanisaPlatform/Publishing/612/774_f.SAL_Public.html )

- it is possible to see the device in /proc/bus/usb/devices (its the 
second device, has multiple interfaces):
- After connecting the device it is possible to see two instances of 
hcid. One is stuck in non-interruptible io/sleep (it will stay like that 
until the device is disconnected):

/proc/bus/usb # ps w | grep hcid
 2411 root        724 S   /usr/sbin/hcid -f /etc/bluetooth/hcid.conf
 2423 root        224 D   /usr/sbin/hcid -f /etc/bluetooth/hcid.conf

~ # hciconfig hci0 -a
hci0:   Type: USB
        BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
        DOWN
        RX bytes:14 acl:0 sco:0 events:1 errors:0
        TX bytes:6 acl:0 sco:0 commands:2 errors:0

~ # hciconfig hci0 up

The command does not return (at least for a few minutes).
When I disconnect the device, the following error is displayed (before 
the prompt is displayed again):

Can't init device hci0: Input/output error (5)


- syslog output for connecting the dongle :

Mar 27 12:48:07 Device user.info kernel: usb 1-1: new full speed USB 
device using uhci_hcd and address 5
Mar 27 12:48:08 Device user.info kernel: usb 1-1: configuration #1 
chosen from 1 choice
Mar 27 12:48:08 Device daemon.info hcid[2411]: HCI dev 0 registered

path:/org/bluez/hci0 fallback:0
Mar 27 10:51:29 Device syslog.info -- MARK --

- syslog output after disconnecting:

Mar 27 13:02:20 Device user.info kernel: usb 1-1: USB disconnect, address 5
Mar 27 13:02:21 Device daemon.info hcid[2411]: HCI dev 0 unregistered
Mar 27 13:02:21 Device daemon.info hcid[2411]: Unregister 
path:/org/bluez/hci0
Mar 27 13:02:21 Device daemon.info hcid[2411]: Device hci0 has been removed
Mar 27 13:02:21 Device daemon.err hcid[2423]: Can't init device hci0: 
Connection timed out (110)

One trace appears when the device is unplugged :
hci_usb_intr_rx_submit: hci0 intr rx submit failed urb c3d70bd4 err -19

Any pointer is welcome,

Best regards,

Frederic
