Ignore timeouts during initialization.

Browse Source 
Some Veo devices never respond to the initialization command, but have
no problem to continue the communication. Therefore a timeout with no
data received is ignored. If there happens to be a real problem, it will
be catched when sending one of the other commands afterwards.
