Would you know of a function that could indicate if USB is available on the current emulator?

Haven't checked, but a quick look at the code suggests that may
not give the correct answer if the USB is provided by an emulated
PCI USB card?

It is ok. I have solved this problem by I think checking for a USB bus.
