Hi,


after trying around with my ancient bcm2033 bluetooth dongle i found it

not working in 2.6.24 - I debugged udev and found it loading the

firmware correctly but the device seems to have problems disconnecting.


I found an Ubuntu bug which mentions a patch which supposed to be

2.6.20 material. It still applies and fixes my problem:


Ubuntu Bug:

	https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/85247


Patch:

	http://launchpadlibrarian.net/7058766/bcm203x-2.6.20-backport.diff


So it seems this patch never went in but most likely should.

we moved away from using a timer and using a workqueue now. It wrote the

patch to use a workqueue and tested that it works. Starting with 2.6.19

we the usage of a workqueue is default. Can you verify that non of the

kernels 2.6.19-2.6.23 are working. We might have missed a change inside

the USB subsystem within the 2.6.24 timeframe.


Regards


Marcel

Hi,


I went through the kernels i still have on this box (FSC LifeBook E8110)=20

and here are the results. Except the debian 2.6.18-5-686 no newer kernel=20

works. The onboard bluetooth works like a charm always whereas the

bcm203x simply does not reconnect after loading firmware from 2.6.19 on.


	2.6.18-5-686 (debian)	works

	2.6.19			breaks

	2.6.21-rc5		breaks

	2.6.22-rc5		breaks

	2.6.22-2-686 (debian)	breaks

	2.6.23-1-686 (debian)	breaks

	2.6.24			breaks


It basically looks always like this:


	<insert>

		usb 1-1: new full speed USB device using uhci_hcd and address 2

		usb 1-1: configuration #1 chosen from 1 choice

		Bluetooth: Broadcom Blutonium firmware driver ver 1.1

		usbcore: registered new interface driver bcm203x

	<wait for 30 seconds - then pull>

		bcm203x_complete: URB failed with status -84

		usb 1-1: USB disconnect, address 2

My tests were on 2.6.24 which does not work as described. Newer

kernels dont boot due to crash in ide-cd so i cant test ...
