I'm using Windows XP and Windows Vista x64 for developing, and it works on both.
I expericened the discriped problems too, but after a Hotfix form MS (via autoupdate) whitch should improve the compatibility of vista the problems where gone.
(also whith the 1.0.1a version)

sounds to me that we need to have the loading screen redraw,
and do more of the loading in background threads.

this would make it all round nicer on all platforms anyway I believe.

Is it possible to determine which hotfix it was? Cause if we know that we could offer a solution for the Vista users who still have the problem (non-auto update users, illegal copies..).

Gonna test this on my GFs comp tmr, if it works there - all bare Vita systems should work flawlessly then - THEN we can close the ticket :P

Loading screen redraw would be nice anyways, remember the loading bar I wanted to do? Have a look at StepManias loadingscreen, it sure needs more time without any output - but it does look broken if nothing moves on the screen..

I can't say whitch update fixed the problems. Itjust started to work afer an update.
I googled a bit and may be the fixes discribed on this page where responebile.

USDX works on both of my Vista (last windows update on 20th november) computers.

Maybe one of the following patches fixed the reported problems:

July 2007 Windows Vista Application Compatibility Update

Cumulative update rollup for USB core components in Windows Vista

October 2, 2007

I found out why Vista resisted to start USDX, and you'll probably laugh:
Vista checks if something like a microphone is plugged into the 3,5 jack. So if nothing is plugged in, Vista denies that it has any input devices - which causes USDX to hang up in the loading screen.

We can solve that in two ways.
First one:
We write it into the documentation, to the blog and the wiki. A sentence like "Plug in your microphone if you want to start USDX", which would save us work - BUT I really wouldn't recommend that way of "Bugfixing".

Second one:
We check if there are microphones plugged in (we already do that), if none are found we simply pop up a error dialog (already implemented) stating that there were no input devices found, maybe we could even start a "Input Device Wizard" then.

hmm strange that users reported this kind of issue..

then again...

who wants to open a SINGING game without using any mic?

maybe indeed an idea, like there was in windows 98, if yeah loaded up windows 98, with nu ps/2 mouse and used a serial mouse or a usb mouse, you would get a message telling you that no PS/2 device was detected and that you could plug in a PS/2 compatible mouse, maybe such a think could be implemented into USDX? that USDX dectects whether or not a mic is put into a jack (even the AC97 audio drivers have this), plus, this way, if the users get's this message, in any OS, they know: ok i need to plug in some stuff to use this program/game propperly

mh current runk works for me von vista even without having a micattached

let's close it then..
