I'm developing a Windows Mobile app using the .NET Compact Framework 3.5 and VS2008, and for debugging using the Device Emulator V3, on Win7, and seem to have constant problems with Windows Mobile Device Centre (6.1) connecting.
Using the Emulator Manager (9.0.21022.8) I cradle the device using DMA in WMDC. The problem is it's so flaky at actually connecting that it's becoming a pain.
I find that when I turn my computer on, before I can get it to connect I have to open up WMDC, disable Connect over DMA, close WMDC down, reopen it again, and then it might cradle. Often I have to do this twice before it will cradle.
Once it's cradled it's generally fine, but nothing seems consistent in getting it to connect.
Connecting with physical devices is often better, although not always. If I plug a PDA into a USB socket other than the one it was originally plugged into then it won't connect at all. Often the best/most reliable connection method seems to be over Bluetooth, but that's quite slow.
Anybody got any tips or advice?

I thought I'd add some notes to this so I could close it off. Generally I found not the following to make it a little more stable:
1) Don't setup a partnership. While this doesn't provide a major issue, if there is a partnership in place, a blank dialog window pops up whenever I connect a device.
2) Always make sure you connect the device (via USB) to the same USB port that it was first on when the device driver was first installed. Moving the lead to a different port will often cause the device to not connect.
3) If it doesn't connect then opening WMDC and un-ticking allow DMA connections, close the WMDC screen, re-open it and re-tick the DMA option, and it will generally suddenly connect.
4) Also if you're using the device emulator and have it cradled, ensure you disconnect the ActiveSync connection before saving the state of the device when closing it. If you fail to do this it will no be able to connect when you restart the device, until you fiddle about with the connection enough for it to realise that it's not actually connected.
If anybody else has any tips to making it more stable then feel free to add them in.
