| Post subject: | Help with a USB to serial adapter for IR receiver |
I am stumped and unsure what to try next... I have a new machine (Dell 531s, dual core Athlon 4000) replacing an older HP machine that has worked fine for years. I have a serial IR attached and it works fine. The new one has no serial port so I bought a usb to serial adapter. The adapter is recognized but I cannot get the IR receiver to be recognized and I am past my knowledge now. Specific info follows... root@mythtest2:/# lsusb Bus 002 Device 001: ID 0000:0000 Bus 001 Device 003: ID 067b:2303 Prolific Technology, Inc.

It looks like lirc is running as you have both lirc devices in /dev. Have you tried running irw yet? Bruce S. |

I have and I get no response. As best I can tell everything looks like it should work but I am missing something... Any other ideas? |

Hi, I see this as two separate issues.. no irw response & usb/serial For the usb receiver, I use the 150 with dogbone. Assuming R5F1 some folks have had to make a couple of tweaks in the hardware config to look at the correct location. There was just a post today in a different section about this very item. Also I think tjc's Hints&Tips covers this issue at least in part. Maybe some can help further with the usb/serial as com ports are rapidly disapearing on new boxes we will this more frequently.. Mike. |
