Another interesting thing to note is the Mini-USB port. It’s actually eerily similar to HTC’s traditional ExtUSB ports. In fact, it looks just like it except that it’s symmetrical enough to only fit a Mini-USB connector inside.
There’s not too much to note on the front except the USB PHY, which we believe to be developed by SMSC. Again, similar chips with similar markings were found on other devices.
