Read values from custom USB device
Frage
I have a USB device (bicycle computer) and want to read from it values (odometer value, average speed, etc.) through the USB port. After some steps I managed to detect the computer and read some parameters (like vendorId
, sessionId
, deviceName
etc.), but I don't know how I can read bicycle values.
There is no documentation for this device. I am looking for a solution on an IOKit framework.
