Since starting with OpenIndiana, I have encountered a problem that
sometimes the keyboard is claimed (in /var/adm/messages) to be removed
and then immediately restored with exactly the same messages as if the
keyboard was physically unplugged and then plugged back in. This
happens up to three times per day. I encountered this with a Sun Type
7 keyboard (two units tested) and a Logitech keyboard.
When a KVM is involved, then all connected hosts see the same event as
if it originates from the keyboard (or is specific to the keyboard KVM
input). When using the KVM, Solaris 10 and Windows 7 hosts recover
properly but with OpenIndiana the keyboard input is dead, even though
similar messages are produced as for Solaris 10, or for physical
replug.
The messages are similar to this:
Sep 27 04:01:10 weerd genunix: [ID 408114 kern.info]
/pci@0,0/pci15d9,62c@1d/hub@1/hub@1/keyboard@2 (hid9) removed
Sep 27 04:01:11 weerd usba: [ID 912658 kern.info] USB 2.0 device (usb430,a2)
operating at low speed (USB 1.x) on USB 2.0 external hub: keyboard@2, hid9 at
bus address 7
Sep 27 04:01:11 weerd usba: [ID 349649 kern.info] Sun USB Keyboard
Sep 27 04:01:11 weerd genunix: [ID 936769 kern.info] hid9 is
/pci@0,0/pci15d9,62c@1d/hub@1/hub@1/keyboard@2
Sep 27 04:01:11 weerd genunix: [ID 408114 kern.info]
/pci@0,0/pci15d9,62c@1d/hub@1/hub@1/keyboard@2 (hid9) online
If I unplug and replug the keyboard into the KVM, or into the host,
the keyboard recovers.
If I plug the mouse into the USB hub in the Type 7 keyboard, then the
mouse is removed as well when the keyboard goes away, except that the
mouse always recovers.
The hardware involved (for OpenIndiana) is SuperMicro hardware and is
a Sun Ultra-40 M-2 for Solaris 10.
I am told that recent OmniOS exhibits the same problems when using
SuperMicro hardware and that a cold boot of the system is necessary to
unhang the keyboard since otherwise the USB bridge on the motherboard
does not re-initialize properly.
Do others experience this problem (hung keyboard)? Is there a
work-around to avoid the hang?
