USB devices aren't recognised

simon_w · 08-24-2005, 12:15 PM

lsmod | grep scsi

Code:

scsi_mod              127972  3 usb_storage,sd_mod,libata

Is that what you mean?

The pen drive is functional and formatted - it has some work on it

Do;
rmmod usb-storage
insert the pen drive and do
modprobe usb-storage
then do cat /proc/bus/usb/devices
Check to see if the device has been seen.

Silly me, I found out the camera I was using needs to be turned on! Maybe you need to do something similar?

simon_w · 08-25-2005, 02:56 AM

@ TigerOC - Thanks, I'll have to try that tomorrow as I forgot my pen drive today

Err, no.

I had the same problem with the standard Debian kernel with my asus P4P800.
To make usb joystick, pendrive, mouse, etc. work i had to plug them in before turning on the machine.
So i tried recompiling the kernel with the custom configuration i use on slackware (usb-storage,scsi mods, etc.).
Now all works ok.
I think that the maybe the problem is with PNPBIOS support. In my config it is all disabled.
So maybe you can try to turn it off and recompile.

Bye

P.S: Sorry for my bad English

Nope

Just tried with three different pen drives.

@xAllanonx - Thanks, but I've only compiled my own kernel once before and as I use this pc for work I can't afford to risk breaking it.

simon_w · 08-30-2005, 07:29 AM

So it appears there is no way to get usb devices working without compiling my own kernel?

TigerOC · 08-30-2005, 09:40 AM

Most of the usb support drivers are in module form. Do modconf and check to make sure that you have the necessary modules installed. It is unlikely that the most common usb modules have not been made available in your current kernel. You can check what the current configuration is by examining /boot/config-<kernel_version>

I've look through modconf several times, but how do I know what the necessary modules are? Granted, some module names such as usb_storage and usbcore are obvious, but what about any others?

USB related modules that are currently loaded are:

Code:

usb_storage
usbcore
scsi_mod
ide_core

Looking at earlier reply in this post I seen you had the uhci_hcd module loaded. That is used for USB ver 1.0-1.1 controllers. And ehci_hcd is for 2.0 controllers.
Do you have both type of USB controllers on the board?
If so have you tried all USB plugs?

You have enabled the vfat module under file system modules?

Hello!
I'm glad I finally found someone who encountered this problem!
Here is a little sum-up of the symptoms:
_ usb devices (camera, pen-drive, joypad, scanner, printer) work perfectly if plugged to the machine before booting.
_ usb devices are not recognized if plugged after booting the machine.

Here is my config:
Debian Sarge
Pentium IV - kernel 2.8.6-2 i686
512 Mo RAM
GeForce 6600GT - nvidia drivers installed

Hotplug & udev installed & working
Kernel modules present & loaded (not a suprise as the devices work perfectly when recognized during boot process I suppose)

Here are some things I can tell :
_ when I plug a device : nothing appears in /var/log/messages nor in dmesg
_ when I unplug a recognized device : usual messages appear in /var/log/messages

_ when I restart hotplug ( /etc/init.d/hotplug restart ) : only previously recognized devices are listed in lsusb.
Let's take an example. I boot my machine with my camera & joypad connected. They are recognized & working.
I decide to plug my scanner or my pen drive. They are not recognized (ok

) I restart hotplug & only my camera & joypad (present at boot) are recognized, the newly plugged device is not seen.

After a hotplug restart, here is what dmesg tells:

Code:

ACPI: PCI interrupt 0000:00:1d.7[D] -> GSI 23 (level, low) -> IRQ 193
ehci_hcd 0000:00:1d.7: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller
ehci_hcd 0000:00:1d.7: BIOS handoff failed (104, 1010001)
ehci_hcd 0000:00:1d.7: can't reset
ehci_hcd 0000:00:1d.7: init 0000:00:1d.7 fail, -95
ehci_hcd: probe of 0000:00:1d.7 failed with error -95

Given this ... I don't know what this error means or what to do. I've checked my BIOS config, but evertyhing seems to be enabled. Maybe a kernel update would do?
I don't extacly know what PnP support is, nor how to disable it as suggested above.

I'm stuck at this point and found no help yet

I hope something in my post will ring a bell to someone

...

This is a setting in the bios and and is a MS thing. Go into the bios at system POST. Normally tapping the Del key during the POST phase. Some proprietory boxes use F keys which would be described in the manual. PnP is normally listed under peripherals and should be disabled.
Have you installed the discover package?

OK, I found nothing regarding this in my BIOS. I'm running an Intel Desktop D865GBF motherboard ...

Yes, it is installed. Here is detailed info:

Package name - Version

discover1 - 1.7.7
discover1-data - 1.2005.01.08
libdiscover1 - 1.7.7

discover1 is based on libdiscover1 and discover is based on libdiscover2. I don't know the difference ...

AmbroiseF · 08-31-2005, 07:36 AM

Well... I just tried removing discover1. I lost my sound card, and our problem wasn't solved. I installed discover. Nothing changed. No sound. No USB. I reinstalled discover1. Everything returned to normal, and USB wasn't working.
Yert, I found this : http://www.thisishull.net/archive/in...p/t-21146.html
but I absolutely don't understand what this is

Hope this could help ...
