Hi, I have device, that implement Communication Device Class. And want to connect it to my machine. On Windows give system proper inf file with vendor and product id, I was abble to communicate with device using virtual com port and hyperterminal. Now I want to use it on linux. But the problem is that there are already several devices connected to my machine, that use usbserial indirectly. If I remove pl2303,ftdi_sio,usbserial, then run insmod usbserial vendor= product= All ok: usbserial_generic 4-2:1.1: generic converter detected usb 4-2: generic converter now attached to ttyUSB0 usbcore: registered new interface driver usbserial_generic usbserial: USB Serial Driver core but when other devices connected, I type modprobe usbserial vendor= product=, and nothing happened. So question, how can I use usbserial generic, if I already load and work with: pl2303 and ftdi_sio? -- 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
