[Bluez-devel] Suspend locks up usb

[Christian Reiser]

Hi,

i have a little problem with bluetooth on my Thinkpad 600e. Every time
when suspending (apm -s) while the usb bluetooth dongle is still plugged
in (that means: the modules are still loaded), usb is no longer
operational after the wakeup. (Un)Plugging of the dongle or any other
device is not recognized. As the module-use-count is not zero, i cannot
unload the modules and try it again.
Module                  Size  Used by
hci_usb                12360  1
bluetooth              41700  1 hci_usb
bcm203x                 4772  0
firmware_class          7520  1 bcm203x

The log states:
Aug 21 14:48:53 alpha apmd[9065]: Suspending now
Aug 21 14:49:16 alpha hub 1-0:1.0: resubmit --> -108
Aug 21 14:49:16 alpha hub 1-0:1.0: hub_port_status failed (err = -108)

I have the newest bluez versions in use (Gentoo):
bluez-hciemu-1.0
bluez-firmware-1.0
bluez-hcidump-1.21
bluez-libs-2.19
bluez-utils-2.19
Linux version 2.6.12-mh2

The problem seems to be independend of the used dongle: I tried LevelOne
MDU-0005USB and Broadcom WTB-3020.

Unloading the modules before suspend might help - i just try not to
forget to unplug it before suspending ;-)

Ciao
	Christian

I can't tell you anything about the APM. Did you tried to use ACPI? What
kernel version is this?

However to unload you module you need to do a "hciconfig hci0 down"
first. This will deactivate the interface.

Regards

Marcel

Sorry, this is a Thinkpad 600e (400 Mhz, PII). APM is working well -
ACPI won't.

Linux version 2.6.12-mh2

Okay - did not know this. But it does not entirely solve my problem. The
bluetooth modules can be unloaded after executing hciconfig - USB is
still dead. Syslog:
Aug 23 10:20:35 alpha uhci_hcd 0000:00:07.2: Unlink after no-IRQ?
Controller is probably using the wrong IRQ.
Aug 23 10:20:41 alpha usbcore: deregistering driver hci_usb

Anyway. I borrowed an USB-Memorydevice and suspended... same problem.


So: This is not a bluez-bug.
============================


Sorry Guys - i will look for the USB-developers list ;-)


Thanks for your help && Ciao
