You mean the "generic" one? That's does not mean it is "supported" at all, only that it happens to have a pair of bulk in and out ports :) You want and need line speed settings, which the generic driver will not provide you. > If i use minicom to communicate to the firmware of the device, i can > read some things, but i can not write to it, i firstly thought it was an > encoding problem, but then when searching the kernel messages i founded > that there was something more (check my other email for details about it). > What i am needing is some documentation about usb-serial module > implementation, but as you said there isn't :( There is no need for documentation about the core usb-serial module, from a device standpoint. It only handles bulk pairs of endpoints to shove data through. I was referring to the USB standard for usb to serial devices. thanks, greg k-h Using Tomcat but need to do more?
