Why do I have to reboot to use the USB ports?

[Tyrannocaster]

I've been using Linux Lite [4.0] for several months now with mostly no problems. However, there is one dealbreaker which I have been putting up with that has just gone too far. I didn't really understand the problem until yesterday, when I figured it out - although I only figured out the symptom, not the cause. I thought the USB performance was just erratic - sometimes I could copy files to a USB drive, sometimes I couldn't. Yesterday I figured out that when I can't copy to the USB drive, I have to reboot and it will work...until I remove the USB drive. From that moment, no matter what drive I stick in the USB port, the system won't let me copy anything to it.

Is there some way of re-initializing the USB port to avoid this? Obviously, this is not sustainable in a workflow context.

The machine is a HP Pavilion p6110f, if that helps.

Thanks,

Ty

I have no problems on linux lite 4.4. Upgrading within series is simple via lite upgrade.
And if not working install updates with "install updates" before upgrading.

Well, I had this problem all along and apparently nobody else did with 4.0 because I posted about it several times - I just didn't know I had to reboot. The 4.0 has been upgraded every week so it's as current as it can be. I'm not willing to go to 4.4 unless I have a good reason, and so far I don't see why the upgrade would fix it for me when nobody else had the problem before. It's very frustrating.

Maybe I should try booting off the 4.4 install ISO and see if I still have the problem.

I was hoping there is some sort of command line thing that would let me re-initialize the USB port. It seems really peculiar that the USB port works on bootup but stops letting me copy to it after I take a drive out. It reads fine from the re-inserted flash drive, though.

So nobody else has had this issue at all. That makes me feel special.

Are you running Linux Lite as a VM in Qemu or OracleVB?

LOL, I wouldn't even know how to do that! No, it's just a plain installation on a SSD. I just booted from a Bodhi Linux USB and tried using the flash drives and they all worked fine after removal and reinstallation. I haven't tried with a Linux Lite USB because I have to burn one and for some reason I seem to be short on drives at the moment. I need to try that, because maybe the Linux Lite USB disk will work fine too - that would be a real drag if it's just something that happens on an installed version.

But at least I had to reboot to get out of the Bodhi live disk, so I have one use of my USB disk left before I have to reboot. :-)

Hello Tyrannocaster,
you can reset the USB sub system these ways without rebooting - https://askubuntu.com/questions/645/how-...mmand-line 

PS I gave you +1 for your comment, now you is special.

[Tyrannocaster]

Thanks for the +1, LOL!

Wow, that thread has a lot of stuff in it. I did try one but got an error message ("sh: 1: cannot create /sys/bus/usb/devices/1-4.6/authorized: Directory nonexistent") so I will need to go through the whole thread, but it looks encouraging. Thanks a bunch!

[Tyrannocaster]

I've gone over the thread and it's just over my head. This is one of those times where it really is true that "Linux is free if your time isn't worth anything", I'm afraid.

Freedom isn't free.
