OK, so you had a keyboard in this port during the last boot. Is this keyboard always connected to the same port? There is no bus 1 port 2 device on your earlier lsusb output, so it was either not connected there or not detected due to malfunction.

So this port was getting reset in the past. Can you also check: - how many of those resets were followed by "HC died" - if all "HC died" events were caused by resets of port usb 1-2 (or some other port)
And for the record, what exactly was the original problem which you reported to Suse and believe to be caused by a kernel upgrade? Was it "HC died" and loss of multiple devices, or just the keyborad failing to work and spamming "reset USB device numebr x", or something else?
