Re: Mode/Status not updated in shared mem mode

Hi, its not about Telepathy... :(

its about a middle-ware, which does not flag the validity of its data! I 
wonder, what the difficulty is. In my simple mind, it could be solved by 
a simple semaphore like thing, where read_gps would set it to 0 and a 
new write from the GPS device would set it to 1. So if the GPS device 
disconnects, the semaphore remains 0 and the APP can recognize, there 
there's only obsolete data.

I ran into this problem, because Debian at some point in time (aft. 20 
min) decided to put the USB controller into Power Safe state, despite 
the fact that GPS was connected and working.
