What's happening here? USB and SSD's connections disappeared suddenly

[jggimi]

No significant change - only USB 3.0 has been discovered and attached.

I looked through the OpenBSD mailing list archives and the public dmesg database maintained at nycbug.org, and do not see any dmesgs posted with the same "F11" August 2015 American Megatrends BIOS.

If you post this dmesg to the misc@ mailing list with your symptoms and the make/model of the system or motherboard , it is possible that someone has the same hardware, if not the same exact BIOS, and may be able to provide further guidance.

What is the output of # usbdevs -dv?

During the installation of the OS or post-installation?

Anyway below's the output, post-installation, of #usbdevs -dv:

That output shows that you have a single USB 3.0 (superspeed) controller chip, or that OpenBSD only recognizes that one.

Your mouse (port 5 addr2) and keyboard (port6 addr 3) are USB 1.x devices (low speed) . Your Kingston USB stick is USB 3.0 (superspeed).

On my older amd64 box I only have USB 2.0 (high speed) and USB 1.x (low/full speed):

$ usbdevs -dv

Controller /dev/usb0:

Per the dmesg files betweendayandnight attached and the follow-on discussion, the kernel probe only discovered a single USB 3.0 controller. The dmesg does not report any unrecognised hardware components, and the only device without a kernel driver ("not configured") is the Intel MEI.

Am I right to assume that the single USB 3.0 (superspeed) controller chip is backward compatible with USB 1.xx and USB 2.0 devices?

[jggimi]

It's not what I would expect in a dmesg, which is why I recommended:

1. Checking BIOS settings - you reported an attempt above.
2. Making an informal problem report to the OpenBSD misc@ mailing list, describing your hardware, posting your dmesg, showing the USB disconnects.

The latter may help because:

• It is a much larger audience -- there are 4600+ subscribers at the moment.
• Someone may have the same hardware, and have guidance for you.
• About half of the developers follow that list.

Yes, it is supposed to be backward compatible. That is why your USB 1.xx gear like USB mouse and USB keyboard is listed in that usbdevs -dv output.

Also see the man page of the xhci driver: xhci(4)

I have a further question.

Suppose I boot into the RAMDISK kernel and reach the stage where the following message appears:

(I)nstall, (U)pgrade, (A)utoinstall or (S)hell?

I type s to get a shell prompt.

As an example I do the following stuff like:

#cd /dev
#sh MAKEDEV sd1
#mount /dev/sd1i /mnt
#dmesg > /mnt/my.dmesg
#umount

How do I get back to

(I)nstall, (U)pgrade, (A)utoinstall or (S)hell?

so that I can type i for (I)nstall to proceed with the OS installation?

[jggimi]

# exit

Or

# install

Either will work.
