Didn't know about those drivers nameless. I guess they don't really apply to me though since my U3 uses the same chip as the U1, which isn't in those drivers. Anyhow, I still say on the whole the ASUS drivers are far superior to anything Creative ever made. On my setup at least, the ASUS utility was very small and lightweight. There were two processes run by ASUS. One was the little configuration utility itself, which minimized to the system tray. You can set up your sound prefs, apply EQ, etc. there. The other process was a monitoring process that detected the presence of the USB device. When the USB device was unplugged, the configuration utility automatically closes. When you plug it back in, the monitoring process detects this and boots up the configuration utility back into your system tray.
But since I'm anal and hate ANY extraneous icons in my system tray (I only have 3- windows sound icon, windows network icon, and MSI afterburner) I went one step further. Once I set up my sound settings the way I wanted (applied a slight bit of EQ and set up DH processing), these settings seem to be saved somewhere, since everything continues to work fine even if I manually shut down the two ASUS processes via the task manager. Since I don't need to change anything around, I just blocked the monitoring process from starting upon windows boot. The result is, everything works perfectly with no processes involved. When I plug the U3 in, windows switches the sound output to that device (since I set it up to be the default output device) and DH is already configured since I had done that earlier in the ASUS configuration utility. But since I turned off the monitoring process, the configuration utility doesn't actually load (no need for it to load if I don't need to make changes to the settings). So everything works automatically and zero needed processes. FAR better than the Creative crap. Even if you left the processes to run, their memory overhead is very small. It's totally unnecessary in my system with 8GB RAM installed, but like I said I HATE having any unnecessary system tray icons, and go through extra steps to keep as little as possible from appearing there.
