While I understand your interest, I question whether this list is appropriate 
for such a discussion. I raised the point that the problem was a system one 
so members would realize KDE (with other desktop developers) are attempting 
to resolve a problem they should not, imho, have to address.

I think you miss the point, here. The usb technology does not provide traffic 
lights, nor does it specify intersections. It is more like car manufactures 
who merely define what their cars do, not how they should be driven. It is 
the responsibility of operating systems to allow users to 'drive' their usb 
devices as they see fit and ensure they don't 'crash at intersections'. 
Installing 'traffic lights' requires users obey the system, not the reverse.

I would like to make it clear that users who do remove sticks unsafely, and 
fail to remedy the situation, get what they deserve - a useless stick. I am 
not suggesting the system must be able to guarantee perfect reliability, but 
that it can reliably detect and correct sticks that are removed 'at the wrong 
time', nothing more. 

If I gave the impression that users can act irresponsibly, that was not my 
intention. On the one hand users should know that devices should not be 
removed while the system is working with them, and on the other hand, 
removing a device, while the system is still busy with it, is not 
catastrophic. If systems could recover gracefully, I believe users will get a 
feel when sticks (or any peripheral) can be removed, without being 
technically the wiser.

Regards,

Peter
