Same here !

Standard USB stuff is not really suitable for embedded use.

Due to electrical disturbances the data on the USB line can be corrupted 
and the link between host and device can be lost. In that case the 
_device_ needs to initialize a reconnection. The host can't do that 
because the protocol does not offer this option. But OTOH in many cases 
the device can't detect that the link is lost at the host. You can help 
this by doing your own software in the device and implement a life check 
protocol. But Standard devices don't feature this.
