targets: remove "acm:"` prefix for USB vid/pid pair

Browse Source 
This prefix isn't actually used and only adds noise, so remove it.

It may have been useful on Linux that makes a distinction between
/dev/ttyACM* and /dev/ttyUSB* but it isn't now. Also, it's unlikely that
the same vid/pid pair will be shared between an acm and usb driver
anyway.
