Something interesting I found while writing this: lsusb for me shows all devices I have under root hub 1.1
. It may be that because I don't have USB devices that are high-speed, VMware/VirtualBox doesn't put them under EHCI? It's somehow strange, because I can't find an USB device around that is high-speed(considering what lsusb says)
.
Wait: lsusb from within VMWare
and from the host OS? As in, you either don't have an EHCI controller/EHCI support in the host OS (unlikely...) or you can be certain that you don't have any USB 2.0 devices (not
very likely, but possible...). There are USB 1.1 thumb drives, but I think they'd be hard to find any time recently...
If you are truly only connecting USB 1.1 devices to the system, then yes, they would be handled by the UHCI companion controller, not EHCI...
If you are connecting USB 2.0 devices and they are showing up as USB 1.1 devices, then that might be an indication that VMWare has a problem with EHCI (but it might also be a problem that the virtualized OS isn't properly configured...).
