There is no usbserial protocol due to some "fun" issues with the USB spec group a number of years ago. So this means that you will need to create your own protocol, and write your own driver for it. Or figure out how one of the current usb-serial devices work, and implement the protocol that they use. > Especially i want my device: > - to be recognized as valid usbserial without specyfing id=... > - get flow control to work > > It seems that INT entpoints are not used. For some usb-serial devices, INT endpoints are used, it all depends on what you want to do. > I have also found an example with CLASS_REQUEST in control endpoint, but > it seems they are not called by usbserial. > Should I report one control interface (with INT endpoints) and onother > interface (with IN/OUT data enpoints) , > or just one interface with all enpoints? One interface with all endpoints is the best. I suggest you read up on the usb spec for how devices should work for help with this. good luck, greg k-h ------------------------------------------------------------------------- Take Surveys.
