Hi
Thanks for the detailed report. According to the system log, the device does seem to be on /dev/ttyUSB0 but the serial driver does not find it there.
I notice that you are using the 'USB (for Linux, Mac)' which is a method where BT747 has to look for the best corresponding port. I made some changes in the latest development version where I am more selective on the ports (V1.67.8) so I suggest that you try this setting there.
Further, in the File menu you can find 'Find serial ports'. This will populate the pull down menu with ports that are identified as serial ports. Look what you can find in there and try some plausible port names. You are not required to do this find: you can type the path directly in the port pulldown menu box.
Previous version were working/opening the same port?
Thanks for the quick response :)
I've checked the output of dmesg, and it specifies /dev/ttyUSB0 as being the device the cp2101 converter is attached to.
When trying to use the dev version I get the following.

The serial (com?) ports are fully populated and provide no difference.
Regarding this working before, it's a new device so I've not tried it with this application previously.
I can confirm that mtkbabel is able to connect and download the traces, if that helps?
Hi
If MTKbabel can connect to this port, then it is a good port.
The 'COM' ports are listed by default, the search should add ports to the end of the list.
Is '/dev/ttyUSB0' added? Is there any port added? Do you get a message when looking for the ports (File menu)?
When RXTX reports this message, it indicates that it could not find the port in the list it constructed. This is a superset of the ports I add (I select serial ports only) to the GUI.
You did not indicate the platform you are on but I presume this is Linux. Is it 64bit mode or 32 bit mode? 64bit may still give some trouble - I have one user for whom the driver crashes in 64 bit mode and works in 32 bit.
Heyah
Looks like we are in the same timezone :) Always handy.
I'm running Fedora 10 (Linux gbgh-dsk-00089.sig.ads 2.6.27.9-159.fc10.i686.PAE #1 SMP Tue Dec 16 14:59:37 EST 2008 i686 i686 i386 GNU/Linux).
I should have probably provided these lines as well.

It is a 32bit platform.
When starting the app, and then going to the File drop down menu and searching for ports, I see no messages appear under info, nor do I see a pop up.
The drop down list is not populated with any additional information either, /dev/ttyUSB0 has been specified by me, as you said by typing it in.
One thing of note (possibly), if I don't specify the device manually, some times it comes back with /dev/ttyUSB-1, not sure where it picks that up.
Is there any more debug information I can provide?
Something is going wrong in RXTX.
I suggest you try the 'webinstall' if you did not do so already (http://bt747.free.fr/content/?q=webinstall). It should not make a difference but you can try the latest version and the stable version.
Further you could try a development version of RXTX (http://rxtx.qbang.org/wiki/index.php/Download). This involves downloading and extracting the package and changing run_j2se.sh to point to it.
I would try to look where java goes looking for the file to make sure it is taking those from the package (using "strace -f" and possibly'-e' option (I think '-etrace=file').
Okay, this initial problem was a configuration option on my side, however, running strace/debug of rxtx allowed me to get hold of the errors.
The problem was that my user had to be in the "lock" group on fedora for the rxtx system to work. gtkbabel worked with the user in the uucp group.
I'm still having some issues, regarding downloading of traces, but the device at least connects.
I'll have a poke about, and raise a new ticket if need be.
Sorry for the run around, and thanks for the assistance :)
No problem.
It would be interesting that you post some more details regarding the strace and the group so that your experience counts for other users.
Regarding the strace output, I'm not sure what would be of use, beyond the error "Can't create Lock, read INSTALL" some thing or other, for which of course there was not INSTALL file :)
However, a quick google search revealed that being a member of the following groups solves the problem.
uucp and lock (lock may be sufficient, but as I need uucp for mtkbabel, I've not tested with out it).
Now with me in the above groups, both the devel and stable version work first time.
On opening the application the correct /dev/ttyUSBx device is listed (as opposed to the generic USB for linux line.
Connection wise, every thing works a treat.
