I think many devices has such a bottleneck. On my mobile phone I 
have to select "enable IRDA" too, and then this connection stays open
at least for 3-5 minutes. 
I can think at least of two ways to help solving this problem nicer:
a) pop up a messagebox to ask the user to switch it on (he selected to connect
to the device by hand, so he can just do it, or press the Cancel button).
b) always cache the last contents you once read/wrote to the device.
Then show those contents and update this cache in the background. If a data-type
has been deleted from the device, then the user will get an errorcode like NOTFOUND.

Regards,
Helge
