Cannot Detect Usb Devices

garbo365 · 09-17-2007, 09:17 PM

I am currently running debian etch on my laptop, and cannot detect any usb devices. When I run dmseg there is no type of mass storage device detected. If I try running lsusb, I get nothing. I checked and made sure that udev was installed, and its there. Connecting to the usb port then rebooting doesn't fix the problem either. Google and other threads haven't given me any leads so far. Any help would be greatly appreciated.

Hya,

Does the kernel on your penguin support USB?

Happy Penguins!

What is the best way to find out if my kernel supports USB. Really not sure where to check.

juergen · 09-18-2007, 12:03 PM

Do you see anything at all in /var/log/syslog when you plug the device in?

farslayer · 09-18-2007, 01:16 PM

a couple things you can look at:

Does the system see your USB hardware ?

Code:

username@it-etch:~$ lspci | grep USB
00:13.0 USB Controller: ATI Technologies Inc SB600 USB (OHCI0)
00:13.1 USB Controller: ATI Technologies Inc SB600 USB (OHCI1)
00:13.2 USB Controller: ATI Technologies Inc SB600 USB (OHCI2)
00:13.3 USB Controller: ATI Technologies Inc SB600 USB (OHCI3)
00:13.4 USB Controller: ATI Technologies Inc SB600 USB (OHCI4)
00:13.5 USB Controller: ATI Technologies Inc SB600 USB Controller (EHCI)

at are the modules loaded ?

Code:

username@it-etch:~$ lsmod | grep usb
usbhid                 37248  0
usbcore               112644  4 usbhid,ehci_hcd,ohci_hcd

Watch the messages log and plug in your device

Code:

When I connect to the usb port I get no response on the syslog. Running lspci | grep USB does show my port. Then I tried running lsmod | grep USB and I got no results, so I am guessing that the modules are not loaded. So the next question is what can I change to get the usb modules to load at boot. I'm really new at this and appreciate your patience.

garbo365 · 09-18-2007, 04:08 PM

So I think the problem is definately with the usb modules. When I used modprobe to manually load the modules I get the following.

ip68-13-212-130:/sbin# install scsi_mod /sbin/modprobe
install: cannot stat `scsi_mod': No such file or directory
ip68-13-212-130:/sbin# install sd_mod /sbin/modprobe
install: cannot stat `sd_mod': No such file or directory

lsmod shows these modules, but I modprobe can't find them. Any ideas?

farslayer · 09-18-2007, 09:16 PM

what is the output of just plain old lsmod

It appears the kernel did detect the usb device and assign it to sdb1. If your distro doesn't have autofs or HAL, it will not mount it automatically.
You have to manually mount it as root.

Try this, in the /mnt folder create a directory called usb, only an example. Next as root, type

mount /dev/sdb1 /mnt/usb

if you get no error messages, then it work.

Type df -h to view the mounted device

dv502, you're reading the wrong reply. OP hasn't provided the information you're referring to.farslayer did as an example.

garbo365,

The correct syntax of loading a module using modprobe is,

/sbin/modprobe modulename

Forgive me folks, I was reading farslayer /var/log/messages output, as noted by digen. My mistake...

If none of our suggestions work, try this, as root type

tail -f /var/log/messages, then connect your usb device.

Post the output you get after connecting your device. This will help us see what is happening when you connect the device.

I notice you use lsmod | grep USB, the USB should be be lowercase or you can add the -i option to grep which would ignore case sensitivity. Even if usbcore is listed, after running lsmod, This does not guarantee every usb device will work when you connect to it, especially if the device is proprietary i.e no hardware documentation/specs provided for the linux community to create a module for it.

Post the output of your /var/log/messages as mention above, so we can see what is happening. If you had resolved the problem, let us know. It is good forum etiquette.

Dewayne2 · 09-19-2007, 02:21 PM

what's the lsmod output?

garbo365 · 09-19-2007, 07:36 PM

So here is the output I get for lsmod

Here is the what happens when I run tail -f /var/log/messages and plug in an ipod. I also tried powering it on and off while if was connected to the usb port. Far as I can tell it gives no response.

Code:
