Description Michael Furman 2004-10-12 18:48:58 UTC

I just got a Compaq Persario R3240 laptop and have been trying and trying to get my bluetooth dongle to work.  Just today I discovered that the device doesn't show up in /proc/bus/usb/devices when it is inserted into the USB port.   I figure that this is some sort of hardware or low level driver issue...... the laptop has an nvidia n-force chip set.  Kernel is 2.6.8-gentoo-r4

Looking at the messages file when plugging the device in, here's as far as we get:

Oct 12 11:35:18 localhost kernel: ehci_hcd 0000:00:02.2: GetStatus port 2 status 001803 POWER sig=j  CSC CONNECT
Oct 12 11:35:18 localhost kernel: hub 1-0:1.0: port 2, status 0501, change 0001, 480 Mb/s
Oct 12 11:35:18 localhost kernel: hub 1-0:1.0: debounce: port 2: total 100ms stable 100ms status 0x501
Oct 12 11:35:18 localhost kernel: hub 1-0:1.0: port 2 not reset yet, waiting 50ms
Oct 12 11:35:19 localhost kernel: ehci_hcd 0000:00:02.2: port 2 full speed --> companion
Oct 12 11:35:19 localhost kernel: ehci_hcd 0000:00:02.2: GetStatus port 2 status 003001 POWER OWNER sig=se0  CONNECT

no other messages are shown.  Other USB devices do work.  Those that do work have a line right after the GetStatus line that is something to the effect 

usb: GetStatus
...
usb: new device strings: Mfr=x,  Product=x, SerialNumber=x
...
usb: hotplug
usb: adding x-x:x.x (config #...

etc.  We're not getting this far in this case.  I don't really know how to debug this problem any further.

Reproducible: Always
Steps to Reproduce:
1. plug in usb dongle
2. check /proc/bus/usb/devices

Actual Results:  
Device was not shown in /proc/bus/usb/devices and therefore does not work.

Expected Results:  
the device normally appears in /proc/bus/usb/devices.  An attachment to this bug
will contain the output for this device from another comptuer when it is working
normally.

output from /proc/bus/usb/devices on a working computer

The attached output is from a system running 2.6.4-gentoo-r1

On this computer usbcore is compiled in the kernel and ehci-hcd driver is
loaded.

No bluetooth modules have been loaded but this demonstrates how the device
shows up on the usb bus without any drivers.  I should be able to get this far
on my laptop but obviously can't.

Created attachment 41684 [details]
cat /proc/bus/usb/devices on the broken machine

usb dongle has been inserted... we only see the nvidia nforce device on the usb
bus........

Comment 3 Michael Furman 2004-10-12 22:14:00 UTC

this is specific to ehci

all devices work with ohci so looks like ehci is lacking nforce support? checking on this.

Is this still an issue? Perhaps you could test with 2.6.9 (or 2.6.10-rc1?) and if the problem still remains then post a bug report to linux-usb-devel@lists.sourceforge.net
