Hi,

on a fresh install I have problems with USB hotplug auto-detection. I am pretty confident my kernel is configured correctly because if I boot with the USB stick it is available and can boot mounted fine. However if i unplug and replug it it cannot be mounted again because no device is present (this is not about some desktop environment - no messages in dmesg at all). (Same also for an usbnet USB ethernet adapter. Works fine if plugged in already during boot time. When plugged in during runtime no trace of it in dmesg).

udev/dbus running, (relevant) use flags used are "consolekit policykit usb dbus udev -hal. This is the first time I have to deal with this. On a couple of other boxes it works just fine. I cAn't thing of anything useful. Any input is very appreciated. Please let me know if I should post some more configuration.

Thanks a lot!

Cheers

hal is deprecated for ages, the fact that you have the hal flag in udev tells me that your tree is severely outdated.

I'd recommend trying to upgrade your system.

Missing CONFIG_USB_SUSPEND=y in the kernel? As in, read any warnings printed when you emerge sys-fs/udisks about required kernel options.
If I guessed wrong, you should really provide output of dmesg at the time of unplugging and replugging the device
As well as `lsusb` output when it's attached

Three ideas:

1) don't use your old files without cleaning them up, big time.

2) check /dev/ before an after plunging stuff in. Possibly by piping the output of ls /dev/ to two text files and diffing them.

3) Start over on your kernel from scratch. It may help. Maybe use one of pappies kernel seeds.

Sorry, not much else from my end.

EDIT: I see someone else is not so stumped and beat me to the post.

DaggyStyle, ssuominen, The Doctor - first off thanks for posting. :)

@DaggyStyle it is a fresh install and I tried to indicate I am NOT using hal (see '-' char in front of hal). Did an deep word upgrade + depclean + revdep-rebuild just yesterday. Re-reading my post I have to admit that the tiny '-' might easily be overlooked. Sorry for that. :oops:

@ssuominen CONFIG_USB_SUSPEND=y is set. No messages for package sys-fs/udisks in regards to missing/wrong kernel options. (I double checked to make sure it didn't slip my attention. I know those message relating to kernel options by the ways as I have seen them already.) So this didn't help - but anyway a great hint. :) Will keep this way of checking in mind for the future.
Will append some more detailed output as suggested to the very end of this post.

@The Doctor
#1 not sure what you mean with this. If it is about copying old cofnig files from an existing system - no I didn't do this. (scp'ed world file from another box (to a temp location in my homedir) to have my starting set of packages to be emerged and removed the file afterwards - guess nothing wrong with that?).
#2 Will do together with the other stuff
#3 Well, yes. This would be my last resort.

=====================

I need to re-specify something: I am pretty sure system behaved as described in the original post yesterday. Today it turned out it still doesn't work. Also rebooted into a 3.6.11 kernel to check it out there (as 3.7.4 is keyworded for amd64 - but need it for backlight fn-keys to work - known issue with Asus Zenbook Prime UX31A) it didn't work there too. When rebooting into 3.7.4 again all as described also BUT when rebooting to 3.7.4 again with devices plugged in they worked (also as described before) but this time unplugging and re-pluging them did work repeatedly...

Now I am asking myself if there is a interconnection between my boot to 3.6.11 and the changed behaviour? Will try to reproduce this and edit this post with the result + the promised detailed system information and outputs.

the notion of with hal or hal-less is invalid as your system doesn't support hal in any way.

what are you trying to achieve exactly? hotplug in X11 env? hotplug in cli env?

DaggyStyle. Okay. Later on in X11 environment. But for now dmesg notes nothing when pluggin in USB devices. So there is no /dev/sdXX so nothing to mount manually in CLI/bash also.

Was not able to reproduced that re-plugging worked thing. :(


The Asus Zenbook Prime UX31A has two USB 3.0 ports exposed to the outside. Internally some stuff is USB connected, like webcam and cardreader (both working).

Here is some output (let me know what else could help) and how i produced it:

Hi

at home I checked what this option actually is for and despite its promising name it looks like I do not need it (because it is in the USB gadget section and is doing something different):
Code:

CONFIG_USB_MASS_STORAGE:                                                                                                                                                                                                               
                                                                                                                                                                                                                                         
   The Mass Storage Gadget acts as a USB Mass Storage disk drive.                                                                                                                                                                         
   As its storage repository it can use a regular file or a block                                                                                                                                                                         
   device (in much the same way as the "loop" device driver),                                                                                                                                                                             
   specified as a module parameter or sysfs option.                                                                                                                                                                                       
                                                                                                                                                                                                                                         
   This driver is an updated replacement for the deprecated                                                                                                                                                                               
   File-backed Storage Gadget (g_file_storage).               

CONFIG_USB_STORAGE:                                                                                                                                                                                                                   
                                                                                                                                                                                                                                         
   Say Y here if you want to connect USB mass storage devices to your                                                                                                                                                                     
   computer's USB port. This is the driver you need for USB

   USB flash devices, and memory sticks, along with                                                                                                                                                                                       
   similar devices. This driver may also be used for some cameras

   This option depends on 'SCSI' support being enabled, but you                                                                                                                                                                           
   probably also need 'SCSI device support: SCSI disk support'                                                                                                                                                                           
   (BLK_DEV_SD) for most USB storage devices.   


Whereas the latter (CONFIG_USB_STORAGE) obviously is what I need but as you can see in the dot.config file I had this one set already. :( Also it works when plugged in during boot. Something related to hotplug dtection seems to be wrong. No idea what I missed.

EDIT:Tried it anway. No use. I also maybe found a hint/symptom which could be part of my problem:
/lib/modules/3.7.4-gentoo/modules.usbmap is missing. The same file for my 3.6.11 kernel also missing. On another box (where it works) this file is available for a 3.6.11 kernel. Still depmod is not creating this map file. Trying to found out more.

*bump*
anyone? it is somewhat awkward to reboot every time before usb media can be mounted... what did i miss with my kernel? on every other box i installed usb hotplug works just like that.

Code:

The modules.usbmap file isn't being created anymore because it's not needed. I don't know what this usbmodules thingy is that you're running, but it's not relevant to your problem.

what happens if you restart udev after inserting the usb stick

can you make a static udev link with mknod that works after insertion?

Yes, thanks. Read this in the meanwhile also somwhere in the net.

Nothing, simply restarts. no device available afterwards besides my primary disk.

Just wondered why my harddisk got full. Found out that this messages get written by syslog all the time in an infinite loop:

Hi DaggyStyle,

Yes USB-debug messages are enabled in my kernel. I disabled it to avoid filling my disk again.


Still, could this be related to my USB hotplu issue maybe? Is s/o able to explain to me what this unlink/link messages mean and what could make them end up in an endless loop? Sadly I am not knowledgable in regards to USB device handling..

Cheers

these prints definitely looks to me like debug prints. not sure if removing them will solve your issue but it might worthwhile to check.

Hi DaggyStyle,


Yes they are debug prints. It is the other way round. I enabled them hoping to see where the problem is. Disabled them now again. In both states my hotplug issue exists.

Hub, Card reader, Webcam, not sure 'bout the last line:
Code:

root@zenbook [~]# lsusb
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub

Bus 002 Device 004: ID 8087:07da Intel Corp.
root@zenbook [~]#

EDIT: it is a laptop, so not sure how this keyboard is connected internally. But probably not USB. Thanks for your post. :)
EDIT1:the card reader is the culprit (for the debug messages loop at least. When checking with lshw I found USB-0 through USB-2.

The USB-1 is the relevant one acording to the log loop:
Code:
       *-usb:1
             description: USB controller
             product: 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #2
             vendor: Intel Corporation
             physical id: 1a
             bus info: pci@0000:00:1a.0
             version: 04
             width: 32 bits

And the card reader device is using USB-1-1.2:
Code:
     *-scsi:1
          physical id: 2
          bus info: usb@1:1.2
          logical name: scsi6
          capabilities: emulated scsi-host
          configuration: driver=rts5139
        *-disk
             description: SCSI Disk

So I enabled USB debug again had the loop running. Plugged SD-Card in, worked as expected. According messages in syslog and endless loop continuing. I umounted SD-Card. Looping messages ongoing. I "safely ejected the whole card reader device" (not just the card) by means of gnome and "rmmod"-ed the rts5139 driver and the debug-msg-loop stops and the device deregisters:
Code:

EDIT2:Just re-tested. No need to unload rts5139 module. Once cardreader is ejected its "used by" column in lsmod ouptut goes down from 1 to 0 and the loop stops. No matter if loaded or not.

Sadly the USB hotplig issue persists even after that endless debug message loop is broken. :cry:

EDIT3: instead of a reboot for some usb devices like mice a suspend-to-ram + resume is sufficient...

hi


My problem is not yet solved but at least I found a workaround better then reboot or suspend-resume that requires no root privileges:

Code:
lsusb -v


Also triggers the detection. Still real auto-detection is missing... I am really desperate as of now. :?:

cheers

I'd recommend trying to upgrade your system.


I might be missing something, but isn't his hal-use-flag _unset_?
