Hello to the group.
My remote system is working very well. However, since yesterday morning, I have been unable to connect any logging software (N1MM+ and DXLab). What I noticed was that after I connect to the remote, I plug the USB cable to the RRC control unit and it does not create the Microbit Virtual COM ports.
I have uninstalled Microbit Setup Manger and then reinstalled it (v1.31) hoping that it was a driver issue but obtained the same result - no virtual com ports are created when I plug in the USB cable. I have tried three different cables along with two laptops.
I am using software version 2.91 with a Windows 7 and 10 laptop as well as with a K3s and K3/0 Mini.
Not quite sure what happened. The connector on the RRC does not appear to be damaged in any way.
Any assistance as to what I can try next would be greatly appreciated.
Thanks
Serge

Hi
If nothing at all happens when you connect, no sund or anything from the PC it's probably a broken USB-cable.

Hello Mike. Thank you for your response.
I thought that it may have been the cable so I have tried three different cables with the same result. I also tried two laptops.
I opened up the RRC and the connector does not look broken/damaged. I will try again later on this morning. Will let you know how I make out. Thanks.

OK we have never received a RRC with a USB interface which is not working. So the risk that it is a hardware problem in the RRC is very small. I think we have received one where the USB connector was broken off the PCB but that's all.

Thank you again Mike.
Tried another cable and the error message I receive is that the USB device that I connected is not recognized. The device malfunctioned and Windows does not recognize it. No Virtual Com ports are created. As mentioned, this is the same issue on two laptops.

If you try with Setup manager, can Setup Manager communicate with the RRC ?
If it works with SetupManager it's a PC issue

Hi again Mike.
If I use Setup Manger, I am in fact able to see the ip addresses for both the RRC Control and Radio units.

Mike, when I use the Setup Manager although I do see both the control and radio unit IP address, if I click on the Serial Port Tab, I get an error. See attached screen shot.

Further update.
I am not able to communicate with the RRC Control unit by attempting to use its IP address in the web browser. I am however, able to communicate with the Radio RRC unit via the web browser.

If the SetupManager in anyway can communicate with the RRC the hardware interface and cable is working. The problem is the PC.

Thanks Mike for your response. Please bear with me as I am trying to understand what is going on.
I am in fact able to see the IP addresses of both the RRC Control and Radio units with Setup Manager (btw both units are within my LAN). I am able to use the browse button within Setup Manger to browse to the RRC Radio IP address. I am not however able to browse to the RRC Control unit IP address.
As both Laptops that I tried are connected to the LAN (via Ethernet) as is the RRC Control unit Setup Manager does see both units and provides me with their respective IP address. However, even though the RRC Control unit is connected to the network (Solid Green LED above the USB connector) I am nevertheless unable to access the unit via the web.
I do not have the USB connector connected at this point. Could this problem/behaviour also be related to the loading of the USB virtual com ports? Should I try a factory reset to see if that has any impact?
Thanks

if you cannot browse the unit the IP settings are wrong or the Ethernet Interface is not working.
Factory default reset only resets the IP number and passwords it does not do any magic

Thanks Mike.
Will try to see if there is a problem with my router/ethernet connection.

Hello again Mike.
I replaced both the ethernet and USB cables to be sure that neither one was causing my USB issue. Connected the RRC Control unit to use my desktop computer computer instead of my two laptops.
I am able to find the IP address of the Control unit using Setup Manager. I am also able to bring up the settings in web browser. So it is connected to the network and working properly.
Now, when I plug in the USB cable from the front of the RRC Control Unit to the desktop computer I get the following message that pops up:
USB device not recognized
The last USB device you connected to this computer malfunctioned and Windows does not recognize it.
I am able to connect the K3/0 Mini using the RRC Control unit to the remote K3s (all located within my LAN). As I also mentioned, the USB connector on the front of the RRC unit look fine as well.
Thanks again for your time and effort.

Mike and Serge,
I have had a USB connector come loose from the PCB after several months of use. All of a sudden, I had no COM ports just like you. The USB connector is soldered on to the PCB without any through holes to anchor it. I sent the PCB to RR so they could see the issue. This is definitely a weak area if you use the USB connector a lot.
Serge, if the unit was working fine and it suddenly does not create the virtual COM ports, I would open up the box and re-solder the USB connector. Always look for mechanical failures first. You have already ruled out the cables. The software has not changed and there is no reason to debug the computer. The RRC electronics has been rock solid for me for over 4 years without any electronic failures inside the RRC box except for the mechanical failure with the USB connector on the PCB.

Thank you Nizar. That thought did cross my mind.
The unit has been working properly and I have been using the USB port quite a bit.
I hope to get some time later on this afternoon or this evening to open up the RRC and resolder the USB connector. Will keep you updated.
Thank you very much for your response and suggestion Nizar.

Hello Nizar / Mike
I took the RRC apart and re-soldered the USB connections to the circuit board. With the same result. I tried the unit on three computers with two different cables (just to be sure :-)) I still get the USB device not recognized message. It was an excellent suggestion though. Thank you.
Mike, as I am not sure what else to try, I will see if I can get the unit to you via a friend of mine who travels to Sweden on a regular basis (works for Ericsson here in Canada).
Would that be okay? Could you please let me have your mailing address as I am not sure where you are located in Sweden and the unit may have to be mailed to you from Stockholm.
Thank you in advance.

I think you have stared a new tread for the same topic. As far as I remember you wrote that the Microbit setup Manager can communicate with the RRC. If so the USB interface is working. If the interface is really not working it can't be repaired as the USB interface is integrated in the CPU. And it's not resonable to replace the CPU, the whole PCB need to be replaced. But you can send it to us if you want. address is Microbit 2.0 AB, Nystaden 1, 95261 KALIX, Sweden.

Thank you for your response Mike.
Based on your comments, I will just order a new control unit then.
Thanks to all for your comments/feedback.

Hi Serge,
I posted some links to USB test software the other day.
http://www.remoterig.com/forum/index.php?topic=5328.0
Since you can connect to the RRC through the manager it is very unlikely that there is something wrong with the interface in the RRC. The USB device view software will help you to investigate this problem. At the very least you should be able to see if the USB drivers were ever installed correctly. To do this you do not need to have a functioning connection to RRC. You can also uninstall individual USB drivers from your PC.
It will only cost you a few hours of time before you order another control unit.

Hi Serge,
Sorry I'm a bit too late responding to this, but I just wanted to mention that even if the issue ends up being the mini-USB port on your Control-RRC, you could still use the RS-232 ports for the same purpose. You would just end up with two cables between your laptop and Control-RRC instead of one. Alternatively, you could buy an RS-232 server and have no wires between it and the laptop.
You have, in the mean time, very likely ordered a new Control-RRC, and that's a good thing, but don't throw away the old one. You can still use the old one , even with the damaged USB port, for setting up a fully functional station. After my Control-RRC's USB port got damaged, I ordered a new one, too. The new one is at my home location, and I use the damaged one in my car.
