Today I noticed that USB 3-3 (bottom right when viewed from above) wasn’t working. Only until I unplugged and reinserted the card did it start to work. After some time, I tried again and it wasn’t working again. Again, after unplugging and reinserting the card did it start to work.
The same behavior is observed while sitting in the BIOS.
I tried a different USB-A expansion card in the same slot, and the problem seems to be unique to the slot, not the card itself.
I naively thought a reboot would be enough but no, the above is correct and you need an actual full two minutes off to have the USB-A device return to life. It is not really a workaround: it’s much simpler to just remove and re-insert the expansion cards (and that works reliably)…
@Matt_Hartley is this BIOS 3.06 regression on your radar? I mentioned it in the 3.06 beta thread but i suspect it was lost in the noise… It’s quite a regression, and the workaround (unplugging the USB-A card and plugging it back in) works, but it’s quite annoying…
For those who do not have TLP installed, please try different expansion slots and some A/B testing with the installed distro vs a Live distro. It’s annoying, but it provides to environments from which to test from.
@anarcat For TLP, I’ve used this setting successfully with some devices. Not using with USB-C expansion myself, but am using for DP and HDMI.
thanks @Matt_Hartley ! as it turns out, using another USB-C port seems to have fixed the issue… And anyways, I have switched to a dock now, so the issue is less pressing (or, rather, changed radically), see:
For what it’s worth, I have since then replaced my YubiKey and the problem doesn’t seem to occur anymore.
To anyone else having such issues, make sure you can’t reproduce the problem on another computer first! I haven’t actually tried that, but it does look like the newer YubiKey doesn’t suffer from those issues…
