Issues with 2.6.13-r3 Linux Kernel - SOLVED

[elrod]

Hi, my uirt is not being recognized by a new linux build with 2.6.13-r3.
It works fine on another server which is 2.6.11-r3.

On the failing server when I plug it in I see a new full speed USB device but nothing describing it. The other server mentions USB_UIRT.

Is there a kernel config option that has to be set differently now?
What config options are required?

Thanks,
Eric

That's unusual -- the ftdi_sio driver is what is used in Linux to drive the USB-UIRT. You may want to look and see if it is included in the your new build's distribution.

Jon, I'll look at that. Would you happen to know how I get the module added in via the kernel .config? Is it USB_SERIAL=y?

[elrod]

Ok, found the correct .config options (duh) and now it gives the message "now attached to ttyUSBO". However, that does not show up in /dev. What does show up is /dev/tts/USB0.

So, I changed the lirc to link to that location.

lircd starts with no errors
irrecord says:

Code: Select all

No UIRT device found at /dev/tts/USB0


I'm using lirc 7.1 and the patch.

Help....

That seems odd (with my limited experience of Linux).

Usually it will be placed at \dev\tty\USBx not tts...

If the FTD_SIO is working correctly, you should be able to open a terminal program on the port \dev\tty\USBx and aim a remote at the USB-UIRT and press some buttons and see junk appear on the terminal screen.

Hi Jon, opened a terminal program and nothing was spit out to the console. However, it did make me pay more attention and I noticed something strange:

1) hitting remote buttons makes uirt flash
2) open console on serial port
3) hit remote, flashes once and then no more flashing
4) no output to console
5) close console
6) uirt flashes in reaction to remote again.

Nothing in dmesg.

Any ideas on how to further debug what is happening?

You may want to take a look at the Linux howto posted by another user today.

Thanks Jon, that got me going.
