[solved] USB to Serial Convert Cable - Device node not created

pyther · 2010-01-29 15:04:29

Hello. I have a USB to Serial Convert Cable http://www.monoprice.com/products/produ … 4#feedback

However, the device is not showing up in /dev or at least I can't find it.

dmesg output:

[14172.044094] usb 4-4: new full speed USB device using ohci_hcd and address 3
[14172.234122] usb 4-4: New USB device found, idVendor=067b, idProduct=2303
[14172.234157] usb 4-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[14172.234165] usb 4-4: Product: USB-Serial Controller
[14172.234170] usb 4-4: Manufacturer: Prolific Technology Inc.
[14172.234379] usb 4-4: configuration #1 chosen from 1 choice

I am assuming that I simply need to create the device node and create a udev rule, but I'm not sure how to go about doing this.

There at least 3 reviews that state the device works with Linux.

Any help would great!

I have a pl2303 Prolific USB to serial adapter (it's a gps mouse) and I'm having a hard time getting it working. It seems there is a problem with the driver pl2303 - it should be using pl2303x, but that's not included with the kernel. There are patches on the interwebz but they seem to date back quite a way and I haven't tried them.
I found out from http://www.linuxquestions.org/questions … ce-614758/ that my device should use the pl2303x driver but then other threads say that the pl2303 driver has been updated in later kernels. Whatever, it's not working for me.
Sorry not to be of help, but I'd be interested if you get any further with this.

I have a different usb->serial convertor, but it just works. I can find the device (it has 2 serial ports) thusly:

[2010-01-29 13:04:43 baldr:/dev/serial/by-id]
445 by-id % ls -ltra /dev/serial/by-id/
total 0
lrwxrwxrwx 1 root root 14 2010-01-25 15:24 usb-FTDI_FT232R_USB_UART_A7006o4s-if00-port0 -> ../../tts/USB0
drwxr-xr-x 4 root root 80 2010-01-25 15:24 ../
lrwxrwxrwx 1 root root 14 2010-01-25 15:24 usb-FTDI_FT232R_USB_UART_A7006o4q-if00-port0 -> ../../tts/USB1
drwxr-xr-x 2 root root 80 2010-01-25 15:24 ./

Maybe yours is lurking somewhere similar?

I'm an idiot. I have a custom kernel with no support for the device compiled in/as a module!!

Arch Linux
