hotplug missing shpchp

/etc/rc.d/hotplug start
:: Starting Hotplug Daemon                                               [BUSY] ... can't load module shpchp

                                                                         [DONE]

Hm. I can't find that module at all.

Re: hotplug missing shpchp

I don't use it or even don't know what it is :-) but I can find this:

locate shpchp
/lib/modules/2.6.6/kernel/drivers/pci/hotplug/shpchp.ko

Right now I'm using 2.6.6 kernel from arch packages (no modification). I also have 2.4.26 installed and there is no pci subdirectory at all. That's what I know about this.

modprobe shpchp
FATAL: Error inserting shpchp (/lib/modules/2.6.6/kernel/drivers/pci/hotplug/shpchp.ko): Operation not permitted

Not permitted ... as root ... sigh

Re: hotplug missing shpchp

this is still a problem. i haven't dug into this much but, i think hotplug dies because of this. my epson usb scanner won't work and i think it's because hotplug won't start. i've had it running fine on gentoo with kernel 2.6.3 so i know it works.

Re: hotplug missing shpchp

[root@Asteraceae /]# modprobe shpchp
[root@Asteraceae /]# 

i can load this module (no idea what it is good for), but i use kernel26mm ... i will check for kernel26 soon

EDIT:
kernel26 works too for me - only there i get an error about not being able to sync hub for pci

Re: hotplug missing shpchp

Shpchp and pciehp modules are both related to pci hotplugging:

modinfo pciehp     
author:         Dan Zink <dan.zink@compaq.com>, Greg Kroah-Hartman <greg@kroah.com>, Dely Sy <dely.l.sy@intel.com>
description:    PCI Express Hot Plug Controller Driver
depends:        pci_hotplug

modinfo shpchp
author:         Dan Zink <dan.zink@compaq.com>, Greg Kroah-Hartman <greg@kroah.com>, Dely Sy <dely.l.sy@intel.com>
description:    Standard Hot Plug PCI Controller Driver
depends:        pci_hotplug

So if you don't have any pci hotpluging devices you will not be able to use them :-) If you want to just get rid of errors add these module names to /etc/hotplug/blacklist. Another issue that may affect using them is acpi turned off at boot time but I'm not 100% sure of that. There is a nice explanation of how pci hotplugging works at suse portal site http://216.239.59.104/search?q=cache:uP … ules&hl=en (this is from google's cache because I can't acces suse portal for some reason).

Re: hotplug missing shpchp

Nice, that's solved. But I still get this:

[root@Nectar]-[/home/laurens]-25-#> /etc/rc.d/hotplug restart
:: Starting Hotplug Daemon                                               [BUSY]
cat: /sys/bus/usb/devices/4-1/product: No such file or directory

dont know for sure, but i would check what you have in the /sys tree under bus/usb and if there is nothing, check your fstab

Re: hotplug missing shpchp

I also read that firewire could cause a problem? I don't know about that.

Under /sys:

[root@Nectar]-[/home/laurens]-6-#> ls /sys/bus/usb/
devices  drivers

[root@Nectar]-[/home/laurens]-7-#> ls /sys/bus/usb/devices/
1-0:1.0  3-0:1.0  3-2:1.0  4-1      usb1  usb3
2-0:1.0  3-2      4-0:1.0  4-1:1.0  usb2  usb4

[root@Nectar]-[/home/laurens]-8-#> ls /sys/bus/usb/devices/4-1
4-1:1.0              bDeviceSubClass     bcdDevice     idProduct     power
bConfigurationValue  bMaxPower           bmAttributes  idVendor      speed
bDeviceClass         bNumConfigurations  detach_state  manufacturer  version
bDeviceProtocol      bNumInterfaces      devnum        maxchild

ok, hotplug cannot cat for .../product, because there  is any - but there is idProduct, what can maybe be missing 'product' - is hotplug uptodate? what about libusb? somehow hotplug assumes other names under /sys/bus/usb

Re: hotplug missing shpchp

i disabled hotplug in rc.conf completely it confuses my system too much
and with udev running usbsticks or other hotplugging stuff works too

also permissions set in hotplug(eg.camera rules or scanner rules) work fine if hotplug is not started in rc.conf
