Does your device have a USB Host interface, as opposed to USB Slave? Almost all Palm OS devices only work in slave mode right now. And yes, the device has to open the USB port for it to become active. This is what shorting the HotSync lines does -- it activates the HS app, which then opens the port. -- Ben Combee, DTS technical lead, PalmSource, Inc.
