USB not recognized

[jnich640]

Forgive the "newbie-ness" of question:
None of my USB devices are recognized in FC1.
When I check out USB devices in KDE Contol Center...nothing appears.
Any suggestions.
Thanks

Hi,

We'll need some more details, such as make/model of your computer (if custom made, get the motherboard manuf/make please) and the devices you're trying to plug into the USB ports. An output of the 'dmesg' command before and after you plug devices in wouldn't hurt either

Assuming net access isn't available on your linux machine, here's something you can do to get those log files, should you want to post them (highly recommended)

[code:1]
su -
dmesg >before_usb.log
(plug device in)
dmesg >after_usb.log
tar -cf usblogs.tar *_usb && gzip -9 usblogs.tar
(this tar/gzips up the logs to save space)
rm *_usb.log
(insert floppy)
mount /mnt/floppy
mv usblogs.tar.gz /mnt/floppy
umount /mnt/floppy
(remove floppy and do whatever with the log files to get it here (eg. Windows box))
[/code:1]

I upgraded from RH9 to FC1 and now there is no USBdevfs. /proc/bus/pci reveals no USB devices either on the PCI bus or built onto the motherboard.

I has troubles with my mouse until I specified PS2 instead of the USB that is actually plugged in. (I am using a wireless optical logitec mouse and it's working.)

What needs to be done to activate usbdevfs?
---

Okay, a little follow-up:

I have manually activated stuff by running modprobe loading:

usbcore, ehci-hcd, uhci, usb-ohci

and then I mounted usbdevfs manually as well and running usbview works perfectly as well. So now I am interested in finding out why this doesn't happen automatically. The point of failure appears to be somewhere in rc.sysinit or more properly, in one of the commands being called.

I am having the same problem finding a USB printer, and was advised at LinuxWorld to run USBVIEW to find out what is there. When I try that from the command line it says no such command. Is there something I have to do to get that command activated?

Thanks in advance.

USB View was once included in the RH9 and FC1 distributions unless I am mistaken. However, it does not seem to appear in FC2. Run a Google search for "USBVIEW HOME" and you should find it not at all difficult to find the RPM you need.

That said, are you currently able to access other USB devices?

Can use the whereis command to find out where are the most usefull files:
$ whereis usbview
usbview: /usr/bin/usbview

I have FC2 and usbview comes with the distr.

Thanks to both of you for your input.

Not sure if any other USB devices are recognized because this is the first and most important one I tried. USBVIEW should help.

Well, I tried it and found that it had no knowledge of USBVIEW.

$ whereis usbview
usbview:
$ apropos usbview
usbview: nothing appropriate

I am running FC2 (2.6.5-1.358) with KDE desktop on a vintage 1999 IBM Aptiva (P3-500).

Am I missing something in the install that would have provided the USB support? (I noted that during the startup log, it said Starting USB [OK], and when I looked at the mount command it had a USB entry that mentioned only the USB controller. Do I have to mount a printer?

Sorry for the newbie questons, and thanks again for your help.

If you use yum,

# yum install usbview

You just dont have the RPM on your system yet...
