The specification for usb is at: http://www.usb.org/developers/devclass_docs => Personal Healthcare => Personal Healthcare Rev. 1.0, Errata for USB Personal Health Care Device Class and Personal Healthcare Adopters Agreement. For this device usb only is used to bypass the information from the device to the application manager (at user space). My question is about how I must adding support for it. I must implement a kernel device driver or at user space with libusb?
Personally, I'd like a kernel driver better. But add all the constants and data structures from the Specification to a common header, something like include/linux/usb/health.h, so that it can be re-used for both host and gadget drivers. -- balbi -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
