I dont think that that adapter will work at all. The pin configuration is different.
HTC products have 11 pin ExtUSB and that is a 4-5 mini USB.
HTC products use ExtUSB, which is an HTC proprietary connector that features a USB (with power) and Headset connections in a single combined connector.
You need something like this.
