Just trying to get it as close to the GUI as (un-confusingly) possible. Your average Joe is going to know bupkis about OHCI or EHCI, or 1.1 or 2.0. You could even take the *HCI out of the settings, and nobody would complain ;)
> For showvminfo, just replacing 'USB' with 'OHCI' is probably the simplest change that's not misleading and does not need to go into excessive detail to be accurate.
Perfect! I believe that you're familiar as well with the "K.I.S.S." principle ;)
> For that reason, changing the machine readable output is a big no-no and pointless -- it will break existing software that parses the output, and does not help users who are not expected to look at it. Changing the human-readable output is OTOH perfectly fine.
I thought that you might object to that. I simply wasn't aware of parsers. Which makes sense to keep it as is. If you want to machine parse the settings, you'd better know what's going on...
> I'll also look at changing the modifyvm --usb option, or rather leaving it in place but hidden and adding modifyvm --ohci.
Hey, that's a good one too! Or, something like:
VBoxManage modifyvm --<usbohci|usbehci|usbxhci> <on|off>
while keeping the "--usb on|off" available for backwards compatibility?
