Hello everyone, I've been having trouble with the Nokia QT SDK for Windows 7 64 bit. Can anyone suggest an alternative or solution to my problems?

I am developing an OpenGL ES 2.0 application using QT 4.7.

The first problem I'm having is that the USB Network connection between my desktop and my N900 continually disconnects. At most I can either get 1 or 2 builds sent to my N900 before it times out and complains about "Host not found." What I've been doing is disconnecting the usb connection and reconnecting it. This sometimes fixes the problem for a few mintes (I get to send a build or 2) but then it disconnects again.

When it's not disconnection issues it's rebooting issues. Whenever the N900 feels like connecting successfully, 50% of the time my N900 reboots automatically during the deployment stage when I try to run my application. Here's the output:

Code:
Cleaning up remote leftovers first ...
Initial cleanup done.
Files to deploy: C:/Users/XXXXXX/Documents/Visual Studio 2010/Projects/cityGLes2\citygles2_0.0.1_armel.deb.
*N900 REBOOTS HERE*
Deployment failed: Could not uplodad file 'C:/Users/XXXXXX/Documents/Visual Studio 2010/Projects/cityGLes2\citygles2_0.0.1_armel.deb':
I don't know what's causing this. This happens not only to my application but also every QT example application I build and run using this method.

My 3rd issue is that I'm unable to use the Maemo Emulator to test my OpenGL ES 2.0 application. First, is there a method to accelerate performance of the emulator? It's incredibly slow and choppy even on my beefy desktop (Less than 1 frame/sec in ui/menus). Also, although I successfully linked the emulator with QT creator, opengl es 2.0 applications are unable to run because the SDK complains about the emulator's drivers being 24bit and it's looking for a 16bit environment.
Edit: It's this
Code:
Warning: EGL suggested using X Visual ID 33 (ARGB0888) EGL config 1 (ARGB8888), but this is incompatable
That's outputted in the SDK. I then found this
http://bugreports.qt.nokia.com/browse/QTBUG-9444
Marked as invalid?

I've tried using esbox on a native linux installation but I'm having the same emulation issues (turtle emulation,etc.)

Nokia QT SDK is fully up to date and I've got the latest version of Mad Developer on my N900 (from extras, version same as devel).

Can anyone suggest any solutions/workarounds/alternatives? Thanks!
