How do I check that my USB ports are working?

MoghNX01 · 03-21-2004, 03:18 PM

This is probably gonna come off looking painfully naive... I apologise in advance, this is my first time with Linux and I'm no technical expert

In Windows XP, the OS I am trying to move away from, I know USB devices has been recognised because a handy little noise is made when I plug in a USB device, and a set of little info bubbles appear in my system tray. I at least know that Windows has acknowledged the presence of such devices.

Now... I can't get my USB modem to work (the light on it saying "USB" doesn't even work) and I can't find any drivers on the entire net for my USB printer (not that I'd probably know what to do with them, in any event).

Which leads me to wonder how I check whether in fact my new Linux OS in fact works with the USB ports on my computer. Whether in fact I could plug anything in there and it would work or not. I've installed SuSE 9.0, and the computer is a Medion MD 8000 Titanium, 2.66 GHZ P4, 512MB RAM. THat's about as much as I know

Anyone know how I find out if my USB ports are working on Linux?

type 'dmesg | more' and sift through there to look for any USB recognition.

'lsusb' would also work to display device statistics/hardware.

That is considering you have both dmesg and lsusb. Chances are you do.

run these commands as root.

Thanks for the advice. I'll try it

USBView is a good GUI diagnostic: http://www.kroah.com/linux-usb/

linuxprinting.org is a great place to go to get printer drivers.

As for the USB, Linux doesn't play dumb sounds when you connect USB devices, but it more than likely registers them. Your kernel might not have support for the USB modem though, and to fix that you'll have to compile a new kernel from the sources. However, typing lsusb is a good way to see if your stuff is detected.

I tried Linnuxprinting.org- it seems they don't have drivers for my printer. I was rather suprised and disappointed- I'd been told that Linux generally had more drivers and compatibility than Windows

Still, I'll give the USB stuff a go. Just need to restart computer in Linux to do it. My modem is an Alcatel Speedtouch USB... there seems to be dozens of tutorials on the net on how to get it working- for some reason, I seem to have completed none of them successfully. Hence me wondering whether the USB ports were actually working...

Oh well. Here goes...

Besides for the few manufactures like Nvidia most drivers/modules AFAIK are written once the equipment is on the market. Some manufactures will not release information required to write a driver and therefore must be reversed engineered. In addition, a lot of linux stuff is developed by people in their spare time.
