USB devices aren't recognised

simon_w · 08-23-2005, 12:47 PM

I'm trying to get my pen drive working with my pc at work which has an Intel d865glc motherboard.

uname -r

Code:

2.6.8-2-686-smp

lspci | grep USB

Code:

0000:00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 (rev 02)
0000:00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #2 (rev 02)
0000:00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 (rev 02)
0000:00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #4 (rev 02)
0000:00:1d.7 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02)

lsusb

Code:

Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

dmesg doesn't report anything when inserting or removing my pen drive. I'm guessing this is the important bit, but I'm not really sure what it means

Any pointers?

lsmod | grep usb will show the usb kernel modules. The output I get on Debian Sarge (using 2.6.8-2-k7 kernel) is as follows:

Code:

$ lsmod | grep usb
usbcore               118308  4 ehci_hcd,ohci_hcd

.
There are various different modules for USB support depening on your chipset, so don't expect exactly the same output.

You probably need to insert the modules. The Debian method is to use the console command modconf (as root). If it says command not found then apt-get install modconf. You may need to find a howto relevant to the pen drive and find out what modules you need. In addition to anything else I would suggest installing hotplug and discover packages.

lsmod | grep usb
<code>
usb_storage 70048 0
usbcore 122148 5 usb_storage,ehci_hcd,uhci_hcd
scsi_mod 127972 2 usb_storage,libata
ide_core 142556 5 usb_storage,ide_cd,ide_generic,piix,ide_disk
</code>

Hotplug and discover are installed and have been restarted - dmesg still doesn't show anything

Its being seen as above but won't work unless you setup an entry in /etc/fstab to tell what to do with it. You need to do some reading wrt getting a pen drive working. Google is your friend

simon_w · 08-24-2005, 07:30 AM

But surely dmesg should report that the pen drive has been inserted/removed (without anything in fstab)? I'm fairly sure that it does on my Slackware box at home.

I'll keep googling as well.

Edit: fdisk -l doesn't show anything relating to my pen drive

Computers are non-intelligent. Your system knows the device is there but you haven't told it what type of file system it has in order to read it or where to mount it so that you can read the contents (these must be specified in /etc/fstab). Sorry if I am coming across as a bit difficult but you need to do some work on this, else you won't learn anything.

Shouldn't there be something in dmesg if it does know about it?

TigerOC · 08-24-2005, 08:24 AM

I shouldn't do this but I will. A detailed howto on getting a pen drive to work in Debian can be found here . If you are still having problems after following this guide let us know.

simon_w · 08-24-2005, 08:44 AM

I've already tried all that, but I don't think the pen drive is being recognised at all - any attempt to mount it results in "/dev/sda1 is not a valid block device"

Same goes for:
sdb1
sdc1
sdd1

This isn't the "usual" missing entry in fstab problem.

Ok, I just pinched my dad's camera that is a USB mass storage device, and have followed that tutorial that someone else has put up. I modprobed all the modules, and then plugged the camera in. Typing dmesg shows that this has been picked up:

Code:

SCSI subsystem initialized
Initializing USB Mass Storage driver...
usbcore: registered new driver usb-storage
USB Mass Storage support registered.

However, I cannot seem to find anything when I type ls -l /dev/sd*

Is this the same problem as you then?

That's the result of modprobe'ing the usb-storage not inserting the camera.

It would appear that we have similar problems

Post the output of cat /proc/bus/usb/devices with the pen drive inserted.

That's with and without it inserted.

TigerOC · 08-24-2005, 12:12 PM

Have you installed the scsi module support? There is something missing in terms of driver support because what is listed there is the usb bus on the mainboard. The pen drive is functional and formatted with a file system?
