USB ports no longer recognize anything (Mint 19) [SOLVED]

Post by adamblack » Fri Jul 20, 2018 2:09 am

USB ports were working great until I plugged a hub into the 20-pin port of my motherboard. Once I did that and rebooted, none of the ports worked.

I took that hub back out again and powered off, unplugged, rebooted. Still no USB ports.

lsusb shows nothing plugged in. I'll put a thumb drive into a port and it'll blink once then sit there.

lspci sees the device:

Code: Select all

00:00.0 Host bridge: Intel Corporation Device 3ec2 (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Device 3e92
00:14.0 USB controller: Intel Corporation Device a36d (rev 10)
00:14.2 RAM memory: Intel Corporation Device a36f (rev 10)

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
And Nemo's still set to automount USB devices. Which means I'm out of ideas. Let me know if you've got some! Thanks!

Device a36d, I believe is the USB 3.x Controller. I'm not seeing any USB 2.0 controller in the list. Motherboard 20-pin is normally for USB 3.x.

Any chance USB is disabled in BIOS?

If you have any rear USB 3.x ports, are they working?

Have you tried pulling the power plug on the system and letting it sit for 10 minutes? I'm assuming you pulled the power plug when you added or removed the hub from the system, as USB can have power with system shut down.

Does the hub have its own separate power connector?

Also, please run the following commands from Terminal and post back the results.

Code: Select all

inxi -Fxz

Thanks for the reply!

Not that I can see, but I'm going to double-check it in a minute. I'm gonna boot from the live CD just to see how the USB ports behave.

EDIT: When running from the Live CD, all USB ports behave as normal.

There are two back there; neither of them work.

Did both these things, hence the confusion.

It doesn't, but I did try another one that did before I plugged this one in. It also gave me some weird issues that went away once I took it out.

Terminal cut & paste:

Can you provide links or reference to the hubs you've tried?

I see you do have the standard USB 3.x 20-pin connector on your MB. I'm wondering if there is a limitation on the connector for use with only front ports (no hub).

Also, please run the following command from Terminal and post back the results. I'm wondering if USB was somehow blacklisted due to fault. The dmesg kernel log might have a tip.

Code: Select all

dmesg | grep USB

Well! I may have fixed it in spite of myself.

Late last night I was running through the syslog and noticed a TON (and I mean megabytes) of pci-related error messages. So I looked that up and found this site: https://askubuntu.com/questions/771899/ ... -corrected

It says that you can keep those out of syslog by getting into /etc/default/grub and changing:

Code: Select all

GRUB_CMDLINE LINUX DEFAULT="quiet splash"
to:

Code: Select all

GRUB_CMDLINE LINUX DEFAULT="quiet splash pci=nomsi"
Once I set it back to normal and updated grub, it's all working again! Bonus: those messages are gone from syslog.

Remember, kids: don't fiddle with grub! Especially late at night when you're half-asleep and thinking, "Huh. I'll try that. What could it hurt?" :oops:

Thanks again for your help!

Ahhh....that explains why it's working from Live vs. installed. I was thinking ANOTHER kernel 24 bug, but glad it was simple to get working again.

So, does that fix also make the hub(s) work when connected?

Good question! I'm waiting to retry those until another day.

This is my new 100% Work Computer, and I've got to broadcast a Google Hangout tonight for my subscribers. Both my camera and headset are USB, which made the last 24 hours pretty interesting! :lol:

Once I'm not worried about interfering with work, I'm definitely going to give some thought to trying these hubs out again.
