So, it seems that if I connect my Edirol UA-5 audio thingummy to a different USB port, the computer detects it as a new device and installs it all over again. Also, if I connect it whilst the “advance” switch is turned off, it doesn’t install the ASIO drivers. Indeed, to get it to install the ASIO drivers, I have to turn it off, turn the “advance” switch on, turn it back on again and wait for it to be re-detected and installed as yet another new piece of hardware.
On top of this, my USB hub sucks, because even though it will do USB2, the moment you plug a USB1.1 device into it, it drops all the connections down to USB1.1 – and the Edirol UA-5 simply does not work over USB1.1, so it just disconnects itself, without warning.
In conclusion, I don’t think I’m going to be able to plug all my devices in simultaneously without buying another USB hub to plug the 1.1 devices into. I thought USB was supposed to make all this sort of stuff easier. Bah.
