I suppose there might well be power supply issues when chaining too many
passive hubs and devices off a single USB port on the host controller.
I've now put an active USB hub (separate power source) at the end of
my long-cable hub and so far things are looking good. I'll report back
if my problems appear in this configuration, too.
My setup changed from
[ehci host]<--[usb extension cable hub]<--[usb keyboard (+hub)]<--[usb mouse]
to this:
[power adapter]

[ehci host]<--[usb extension cable hub]<--[active hub]<--[usb keyboard (+hub)]
