[Bluez-users] No communication with USB BT device

No HCI connection is possible with my Belkin Bluetooth module. (CSR chip)

__System__

Linux kernel 2.6.7

bluez-libs-2.7
bluez-utils-2.7
bluez-pin-0.23
bluez-hcidump-1.8

__output__

$ dmesg | grep -i usb
sbcore: registered new driver usbfs

__Order of events__

Boot system
insert dongle [no hotplug system running]
modprobe hci_usb
/etc/init.d/bluetooth start [HIDP complains (ignoring)]

hciconfig shows...[no device params read from device]

hci0:   Type: USB
         BD Address: 00:00:00:00:00:00 ACL MTU: 0:0  SCO MTU: 0:0
         DOWN
         RX bytes:0 acl:0 sco:0 events:0 errors:0
         TX bytes:6 acl:0 sco:0 commands:2 errors:0

hciconfig hci0 up times out.

hcidump show a hci_rlsf command but no response from chip.

This device works fine with Widcomm drivers/stack/application

when same machine is booted into windows XP (shudder)

Where might I be going wrong, What else could I try?

many thanks

Kindest Regards

Rob
