Tellstick DUO not found after ubuntu upgrade

Hi,

I recently upgraded my ubuntu htpc, which is responsible of handling all my telldus businness.

For some reason it does not recognize my tellstick duo anymore.

'lsusb' lists it as it should.
I've tried both with: modprobe usbserial ; modprobe ftdi_sio and without.
No change, I never get a line in dmesg saying it assigned it to /dev/ttyUSB0 or something like that.

uname -a gives me
Linux HTPC 3.2.0-38-generic #61-Ubuntu SMP Tue Feb 19 12:20:02 UTC 2013 i686 i686 i386 GNU/Linux

Also, if the telldusd daemon is started it keeps hogging the cpu at 150% and builds up more and more ram , aprox 1% per second...

root@HTPC:/var/log# telldusd --version
telldusd 2.1.1

I'm not sure where to start debugging this bad boy, any clues?

Kind regards
Tommy

After a modprobe ftdi_sio and usbserial and unplug+plug in of the device I get the following in dmesg.

[ 355.411748] usbcore: registered new interface driver usbserial

Everyone else seems to be getting a line mentioning ttyUSB0, what could I be missing?

That explains why the cpu is hogging anyway..

As you can see /dev/bus/usb/002/025 is the Tellstick DUO

And when I examine the strace it looks like telldusd is going through all the available usb-devices and finds it.
The only apparent error I see is:

ioctl(3, USBDEVFS_IOCTL or USBDEVFS_IOCTL32, 0xbfeb72f0) = -1 ENOTTY (Inappropriate ioctl for device)

I'm not sure if I'm missing something in the kernel or what the heck is going on here...

Re: Tellstick DUO not found after ubuntu upgrade

Ok, after digging around for awhile in the source code I found out that the CPU-hogging problem seems to be totally unrelated to the usb-device.

If the socket-file /tmp/TelldusClient was already created before starting telldusd all hell broke lose.
Which is quite strange, considering there is a unlink(name.sun_path); inside of ConnectionListener_unix.cpp

I added a simple check around it:

Code: Select all

   if (unlink(name.sun_path) == -1)
     printf("Could not unlink %s: %s\n", name.sun_path, strerror(errno));
which gave me the output

Code: Select all

Could not unlink /tmp/TelldusClient: Operation not permitted
It seems perhaps the original telldusd was running with another user/group set and after the upgrade something changed / broke.
Simply removing the file fixed the cpu usage, however, perhaps a check should be added in here to atleast stop the entire application in case of such a fatal error. Instead of bringing the computer down ;)

And I still haven't gotten the device recognized yet :|

Ok, scratch that!

It seems to be working now for some reason, let's just hope it still works after my yearly reboot ;)
