Let me share one solution that I developed recently.
At some point, after numerous reinstallation of Android, my HD2 become undiscoverable for MAGLDR as well as for Android flasher via USB Flasher. I wasn't able to flash anything. "Waiting for USB connection" was displayed until timed out. I did reset phone, removed battery, rebooted PC - nothing happened. I started to think about replacing USB cable.
Here is what helped at the end:
- Disconnect phone from PC
- Open Command Prompt
- Type "set devmgr_show_nonpresent_devices=1", Enter.
- Type "start Devmgmt.msc", Enter.
- Two commands above should be entered in the same command prompt window or it won't have an effect.
- When Device Manager opens select View->Show Hidden Devices
- Expand all nodes and remove all inactive devices - and icon of such device is grayed out
Here is an article about it http://support.microsoft.com/kb/241257
After that when I connected phone with USB cable system reinstalled drivers from scratch and I was able to flash.
