You need the opposite of outb_p(DEVICE_ENABLE, HTCPEN_PORT_INIT); here.
It is actually working; it also works after suspend/resume without any issues. I currently do not know a safe way of disabling the device, as HTC did not offer any specifications or datasheet when I requested, so everything in the driver has been reverse engineered. Let me know if you think it's ok to leave it as is, otherwise I'll try to find the proper way to disable the device (it should not be much different than the way of enabling it).
