Hello, I've been playing around with the Ergodex DX1 keypad and am trying to figure out how to approach the driver. It has two USB interfaces. Interface 1: - A pure USB HID keyboard interface - No problems with the stock usbkbd driver Interface 2: - Vendor specific interface - Programs keys with keycodes emitted on interface 1 - Controls two LEDS - Emits events when an unmapped key is pressed - Sets/clears device test mode I've tested the device using libusb to program the keys and control the LEDS. But, I think there are several advantages to a driver: - Supporting the EVIOCGKEYCODE and EVIOCSKEYCODE ioctls - Handling suspend/resumes properly - Creating LED class devices - Emitting MSC_SCAN events on unmapped keys I've been digging through drivers/hid and drivers/usb/keyboard looking for examples of how to pick up a specific interface and handle it, but I haven't found one yet. Any suggestions? -- 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
