Hi,

I have been using Opensuse 42.1 leap. USBs are not working. They suddenly stopped functioning while I was working on the machine. Could anyone please suggest something? Is this problem coming from OS or some other issue such as BIOS?

Another problem is, the port for headphone also not working.

All of this seems to be happening due to OS..Am I right? is there any fix?

BTW sound issue has been fixed with todays open-suse update.
Few more info:
Model: HP xw8600 workstation
output of uname-a: Linux vlsilab-8 4.1.39-56-default #1 SMP PREEMPT Mon May 1 04:41:25 UTC 2017 (5f49ec2) x86_64 x86_64 x86_64 GNU/Linux
OS: OpenSuse Leap 42.1
I noticed something like as follows was showing during boot:
USB-USB5=port1: connect debounced failed


Thanks & regards,

Your post is too vague. What USB devices are you referring to? Are the devices detected at all?

You should keep your post to one topic. The audio issue should be dealt with in a seperate thread.

@ferrari

My question is only on one topic.
My clear question is: can this kind of problem occur due to opensuse 42.1 leap?

no device getting detected at the USB ports. (That's what I meant by USB port not working)
even though the problem seems different but it happens in one go hence seemed to be triggered by one particular thing.

Hi sudiptaOpensuse,

Welcome to LQ!

With PCs you learn that anything is possible. But try the lsusb command and see if your device is there. And also look here: http://www.linuxquestions.org/questi...osting-356388/

It could be an issue with the OS, yes. Or it could be that its disabled in your BIOS. The headphone thing could be unrelated, has it ever worked? Is this a laptop? What make/model?

Why do you say its happening due to the OS? What leads you to believe that? We dont know if youre right. We need more info from you. Is there a fix, maybe..

When you plug in any USB device it should be enumerated by
and examine the kernel output as well
You could try a live distro perhaps. Assuming it is not hardware failure, it should boot, and USB devices should be detected.

Hi ferrari,

Here are the outputs:
My pen drive was plugged in and it is a working pen drive, I tested it properly.
I don't see any trace of the pen drive.

Hi erik2282,

Model: HP xw8600 workstation
vlsilab-8:/home/sudipta # uname -a

OS: OpenSuse Leap 42.1

I am hoping it is from OS because that can be fixed easily.

I noticed something like as follows was showing during boot:
USB-USB5=port1: connect debounced failed

I googled it. some similar stuff came up and they were OS issue but I couldn't understand the fix.

Thanks & regards,
Sudipta

Unlikely to be OS-specific IMO. (I've never encountered such an issue reported in openSUSE Forums or here.) A quick check online does suggest that it could be due to either a hardware fault or BIOS issue. Start by resetting the BIOS (back to default) if you can

Hi ferrari,

Thanks for your advice. I will try setting the BIOS to default. I don't really know how to do it for this type of machines.
I will try to find out. If you know anything then please let me know.

Thanks & regards,

So I used my USB drive to install Linux, after I formatted in windows (Fat32). When I inserted into my openSUSE Leap 42.3 system it could no longer be detected.
I simply left the USB inserted, and restarted my laptop (Lenovo Yoga 700). And voila, my usb is detected after start up.
Nothing like good old turn off, turn on.

Hope this helps someone.
