I'm not sure I follow. Why should the download stop when I connect the USB cable?
Amending subject for now.

This issue seems to be related to -

[B2G][Contacts][Import]Plugging in USB cable while importing contacts from SD card does not halt import.

Both issues involve the SD card in use prior to plugging in the USB cable.

It starts to make sense. My first guess is that we're not talking about "USB debug", but "USB storage".

From a quick test:
* If I plug the cable before doing anything with downloads, I get warnings that the SD card is in use.
* If I plug the cable after the download has started, memory won't be available until the download is complete.

I wonder if this is just the expected result.

If the app doing the download wants to interrupt the download, then it can watch for events that indicate that sharing is being initated.

Currently, the AutoMounter detects that there are open files on the volume to be shared, and defers sharing until the files are closed.

The Gallery/Music/Video apps detect that sharing is desired and will close the open files.

So I either behaviour is achievable. Which one is "correct" is really a UI decision.
