I own a small radio station. I use a TuneTracker automation system. Haiku is on this computer. It connects to a switcher for contact closures from my main network. It switches between the network and local content. For some unknown reason, the computer STOPS seeing the usb port the cable is plugged into! The computer no longer sees the closures and no longer plays the local breaks. What would cause this? This has been going on since I installed this system 5 months ago. The guy at TuneTracker is clueless as to why this is happening. Please HELP!!!
Iām not sure that I understand what a switcher is in this context. Is it in context of USB or IP network?
Stumbled on this whilst browsing discussions on newly released Beta1 (I donāt normally read forums)ā¦
@korli We ship some stations with a āBroadcast Tools ā¢ Audio switcherā, RS-232 controlled. It routes audio from a given input jack to an output jack, based on commands sent by the computer on the serial port. Another function those switcher/boxes perform beside audio routing, is getting āpingsā (relay closures) from station heads/servers.
We use some sort of chinese-made USB-to-serial converter I think, since motherboards donāt have an RS232 port these days. It uses the pcserial(?) driver on Haiku. Weāve had some problems beforeā¦
Be glad if you can shed some light on this though 
@Bruce - Dane should have āescalatedā that problem to me, sorry it didnāt happen. Did you send a āCare Packageā, including your syslog ? What happens if you try to access the switcher with the SerialConnect application (or do I understand correctly that the switcherās USB port is not even listed in SerialConnect any more ?) Does the problem get fixed with a (warm) reboot ? Did Dane offer to ship a replacement āusb-to-serialā device in case the one you have is deffective ? (weāve seen that occur at least once before IIRC).
Edit: if all else fails, we could try to upgrade your version of Haiku, in case there wre improvements to the pcserial driver; sending Dane a ācare packageā will allow us to see which haiku hrev youāre using, to determine if thatās relevant
Tunetracker uses a nightly haiku or the old alpha 4.1 like Discover haiku?
An upgrade canāt hurt! I use a Broadcast Tools 4.4 Switcher. This is what TuneTracker recommends. It is connected to the computer via a cable to a little red device then a data cable to the switcher. It is plugged into a usb port on the computer. I am sorry, I get lost with computer stuff. I can sometimes fix it with a reboot or 2 or 3! The switcher relays the contact closures to the computer to tell it what to do, start local programming. When the local segment is done, the computer tells the switcher to resume the network programming.
ttcoder: I do not know what at ācare packageā is. Dane has pretty much thrown up his hands on this. He stopped offering help weeks ago. I see the switcher in SerielConnect. But hereās what happens: It will read: Connect to usb0, switcher ss 4.4 #0. This works! But then it will stop working and I see this: connected to usb0, switcher ss 4.4 #1. At this setting, it doesnāt work. I may have to restart it 2-3-4-5 times, unplug and plug it back in to finally get it to reset to ss 4.4 #0.
Intriguing problem.
It is assumed that your radio station has been using TuneTracker all along.
So, something changed about five months ago:
* Was it a new computer system?
* Was it an update to the underlying Haiku?
* Was it an update to the TuneTracker package(s)?
Reading through the release notes for Beta 1 ( https://www.haiku-os.org/get-haiku/release-notes/ ):
SerialConnect
This is one of the last applications which came with BeOS, but we had not written replacement for at the time of alpha4. Itās a relatively simple and straightforward graphical interface to serial ports, with support for arbitrary baud rates and certain extended features (e.g. XMODEM file transfers.)
In the process of developing and using it, various bugs in our USB and PCI/ISA serial port device drivers were found, and thus fixed.
The last commit to SerialConnect dates back to November 2017. There are no commits to serial/USB codes which would correspond to your timing of five months ago. However, there could have been commits to their dependencies and I donāt know how to find them.
Knowing which HRev of Haiku is used for your TuneTracker installation might guide you toward a solution - ārevertingā to an earlier HRev or āupdatingā to R1 Beta1.
Sounds like it could be an application problem as wellā¦ its pretty common for USB devices to get renamed on insertion/removal or rebooting, if there is only ever expected to be one serial device plugged into the system perhaps the software should just look for it regardless of itās name and connect to it. Or allow searching for and selecting it from the UI.
I am extremely happy to hear that TuneTracker is still kicking around!
May I ask why donāt you just run BeOS 5 with TuneTracker?
I am extremely ANGRY with Tune Tracker because I bought a piece of crap from them and they will not fix it! I donāt understand what you are asking. How do I rub BeOS 5 on this Haiku computer? NOTHING i have done has solved this problem that fails every 10 -12 hours. I am sick of dealing with it.
Frankly anger and computers do not mix. I think we have a good idea of what your problem may be but we need more info and like you I have no idea what a care package is (thereās probably some button or menu option that automatically collects system info) You may want to search your Tune Tracker documentation as it may tell you how to do that, I donāt have a copy of it to reference to tell you where to look though. I know it can be frustrating to deal with problems, but I have a lot of experience with that and people often look at me like Iām crazy when I donāt get mad when working on problems like thisā¦ the PC is as dumb as a rock and me getting mad at it helps nothing. Obviously there is some small problem causing a glitch and youād likely be singing TuneTrackerās praises if it werenāt for this.
Be aware that TT Systems may be at their wits end on this issue and they canāt know everythingā¦ and that weāre all just trying to be friendly and helpful here so lets just proceed with trying to gather the pertinent info and proceed from there. Also while I understand your anger with TT Systems, I also work for an OEM and I understand their position as well in any case lets just move on and try and solve this. This problem may be slightly out of their wheel house so to speak if it is Haiku or hardware driver problem and not a problem with TT itself. This is not a slight against them in the least as they are smart guys too. Also communication can be difficult at times for the best of us and especially for gear headed nerd types like myself so yeahā¦
So, for starters you can just manually collect some system info for usā¦ by posting the following information. Open up a Terminal and type the 3 commands copy and paste the output here after running each one.
listusb
listdev
cat /var/log/syslog
Make sure the system has been runing awhile and the issue has occured at least once before collecting the syslog file, rebooting fresh and plugging in and out the USB adapter may also be relevant. Be sure to collect the syslog file separately each time as this allows is some insight into what is going on when you do these things.
Also, did you originally buy this PC from TT systems? Or was it built by a 3rd party and then TT software installed perhaps after failure of the old hardware you were running TT on? This is significant because the version of Haiku they ship may not work on a 3rd party box that is untested any you may actually have better luck with a newer copy of Haiku.
If the Serial adapter is flakey we may be able to recommend a replacement.
Itās also worth noteing that Haikuās stability has increased significantly in the past few years so there is a good chance that upgrading could fix things. there is a small chance it could break things too ā¦ but Iād rather be honest with you up front about that. I have no idea if TT software is compatible with the new package kit if it isnāt that would be a problem for upgrading but it is likely theyāll upgrade thier software to support it soon since the new Beta is now released. (It was 5-6 years since the last official release).
Also Iām sorry if our initial responses werenāt getting to the heart of the matter quick enoughā¦ this forum is a bit different from commercial tech support but weāll try and there are some very knowledgeable people here willing to help.

So you received a turnkey system with Haiku and TuneTracker preinstalled?
Or just use BeOS 5, which TuneTracker was designed to work. BeOS 5 is far more reliable than Haiku. It may work with fewer hardware combinations, but in terms of reliability, BeOS 5 (or even 4.5) is where itās at.
I donāt know where you have been for the last few years, but TuneTracker has switched to Haiku years ago and is shipping that ever since. It was not possible to get BeOS compatible hardware anymore, so they funded some of our development (to get serial ports working, in particular) until they could use Haiku as the base OS.
Back to the original issue. ttcoder is not right about the driver being used, for usb adapters this would be the usb_serial driver. @ttcoder, can you tell me which adapters you ship to your users? Which chipset does it use? (listusb would tell): FTDI, Prolific, something else? I donāt mind looking at the info (syslog and all), if you need some help I can dig into the usb_serial driver and try to improve things on Haiku side.

We usually try to āpull our weightā and not outsource customer support to the community (hope youāll all agree weāve done a decent job of not abusing you guys over the years )
But since thereās this kind of synergy going on, what the heck, might as well try this alternate way of doing support, letās see where it goes! Obviously very humbling to have a station call our stuff c*@p so letās see if we can fix it and restore confidenceā¦
@pulkomandy Iām waiting for what we call a CP.zip from Bruce ā the user just has to click the icon āCare Packageā, in the /boot/home directory (sometimes on the Desktop) to retrieve the syslog, listdev and other information. However, I think the USB-serial adapter we ship is almost always the same. So in case it helps, hereās the syslog excerpt for /another/ station, for which I was doing customer support last week; hopefully it is the same as the one discussed by the OP:

Ok, so you have a Prolific PL2303 based adapter. This is handled by the usb_serial driver. The problem can be at several levels: defective hardware, a bug in the driver, a problem at a lower level in the usb stack or another device on the same usb bus interferring, or it can be a problem with how TuneTracker application detects the switchbox.
Indeed the ācare packageā with syslog, etc will allow us to rule out some of these cases. Iām in vacations now but when I get back home I can probably locate a PL2303 based adapter and do some experiments.
We do use nightlies of Haiku indeed; updating the hrev every 6 months or so (so in the 50xxx - 51xxx range, currently); weāre currently testing a pre-beta nightly (why not the beta itself? As Chris Herborth used to say : Thing. Take. Time. * g* ).
We mostly ship āturn keyā stations with everything pre-installed. In my experience, radio stations donāt want to do ācomputer stuffā, they want the computer to get out of the way and do radio broadcasting and not even realize thereās a computer running the system. Haiku (and BeOS previously) of course has tons of advantages to that end, right out of the gate. Just need the hardware to ābehaveā and be stable, so to speak
We have a handful clients who /still/ run their station on BeOS indeed, and happily so (those old computers were rock solid!). Obviously if their computer breaks down some day weād have to upgrade them to Haiku. Canāt make a BeOS based system from off-the-shelf components; and my software wonāt even build since I use many Haiku-specific APIs. Heck I donāt even use my BeOS computer any more these days.
@Stacked_Lambda I think Bruce is saying this problem has existed since the beginning (system purchased 5 months ago), not that he performed an upgrade ā¦etc that broke a previously correctly working system
@cb88 The settings window of TT/CC allows to pick which āserialā port to use (though generally thereās only one of course)
If you guys know of a model/brand for a reliable USB-to-serial adapter, letās see it, links welcome (even am@zon ā¦etc * g* )
PS - weāre also looking into using a new type of motherboard to build our station computers with; our AMD-based F2A55 style ones gave us too much trouble over the last couple years
@pulkomandy Thanks!
I was not active in the BeOS community, apart from funding Haiku every year since it was founded. So your criticism is spot-on!
