I am connecting a USB to serial driver port to my system and I get about halfway to where I need to go. When it is plugged in dmesg indicates:

<6>usb 2-1: new full speed USB device using sl811-hcd and address 4
<6>usb 2-1: configuration #1 chosen from 1 choice

and lsusb

Bus 2 Device 4: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 2 Device 1: ID 0000:0000  
Bus 1 Device 1: ID 0000:0000  

I get a series of usbdev2.4 (usbdev2.4, usbdev2.4_ep00, etc) devices in dev but no ttyUSB0 or anything that I can open with minicom.

How do I get the system to create the /dev device?

Thanks

Dave

Tough it may belong on superuser. It's one computer and USB isn't generally used in server systems, at least not in this way. –  Omnifarious Aug 30 '10 at 20:30

<6>usb 2-1: new full speed USB device using sl811-hcd and address 4
<6>usb 2-1: configuration #1 chosen from 1 choice

The messages above only indicate you have the basic USB support loaded in your kernel.

I guess you don't have the usb-serial kernel module loaded. What does lsmod | grep serial return?

What distribution are you using? And is the kernel the one bundled with the distribution or have you compiled your own?
