I have two Sun Blade 150 clients, one loaded with Solaris 8, the other Sola=
ris 10.

I noticed that if I put the clients on a "dumb" KVM (Avocent SwitchView USB=
 4-Port), that the Solaris 8 machine works when switching between KVM chann=
els (the /var/adm/messages log shows 20+ usb related events from kernel and=
 usba)

The Solaris 10 machine will not reconnect to the KVM, and I have to SSH int=
o the box and reboot it.

What's going on with Solaris 10?  Why is it not as robust as Solaris 8 when=
 the USB keyboard/mouse is switched on a "dumb" KVM?

Anyone had similar experiences?

When I SSH into the misbehaving Solaris 10 machine and do a "cfgadm", I can=
 see that the USB devices have disconnected, but they are never able to rec=
onnect, no matter what combination of cfgadm commands I try.  Only a reboot=
 of Solaris 10 fixes the problem.  A sub-optimal solution.

And yes, newer "smart" KVM's work (IOGear GCS1734), just not the Avocent.

Any help is appreciated.
