Hi, Thanks for the reply. Right now I am working kernel 3.5. I want to connect USB to Serial device (FDTI FT232R base) and be able to use /dev/ttyUSB. (I can mknod manualy). In fact I am going to connect hub, and I will need up to 4 serial ports. I used make menuconfig - and I marked all the required item, but how I intialize instance of USB serial port driver? I think it require some definition in the .dts file. BTW, I am going to use complete kernel build (no dynamic module loading) I hope I am more clear now Thanks Avner ________________________________________ From: Greg KH [gregkh@xxxxxxxxxxxxxxxxxxx] Sent: Thursday, October 25, 2012 7:19 PM To: Avner Flesch Cc: linux-usb@xxxxxxxxxxxxxxx Subject: Re: PPC Serial over Host USB On Thu, Oct 25, 2012 at 04:42:09PM +0000, Avner Flesch wrote: > Hi, > > I have Freescale's MPC8308RDB board, and I would like to activate the USB as host and use it as Serial port.

In what way? What kernel version are you using? greg k-h -- 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
