Hi Matthias, > * There's at least one other driver which has been cloned from option.c > in the kernel, as well as at least one which is still based on the > "standard" usbserial but shouldn't be. It'd make sense to (re-)unify > these. I think you might be talking about the sierra.c (which was actually cloned from the airprime.c driver)? In a perfect world I agree, it would be great to unify the drivers. However Sierra is slowly but surely adding more and more proprietary feature support (e.g., USB vendor specific commands, change in end-point support, etc.). Granted this still could all be maintained in a single driver it will likely get _very_ ugly. This is not to say we shouldn't encourage collaboration with each other, esp. with throughput issues, those will likely affect all drivers similarly. -Kevin
