We have a number of phones in my household (different makes/models) and generally the computer will always detect a new device when connected via USB (a little pop-up notification will come on the right hand side of the screen).
Try plugging in and unplugging the phone if you don't see it straight away then "click" on the notification to open the location/device.
Alternatively you may find your phone when connected by looking on your PC for "Devices and drives".

Yes, really poor. Hours of waiting and poor response. Phone jammed after three weeks, complete reset, all data lost, Then it jammed again after another two weeks, all they offer is a repair for a known problem. If I wanted a reconditioned phone, I would have saved money and bought one. I think this phone is being sold cheaply because they want rid of their stocks.
