"ERROR: USB Error: An interface is already claimed" when running TomTomWatch

[Skylarkin]

I am running Arch-linux, latest kernel, everything updated. I suspect this has something to do with ttwatch because I tried running TomTomWatch before testing ttwatch and the software TomTomWatch was working, the device (TomTom Adventurer) was recognised with correct serial no. HL4486G01240 and updating Quick GPS worked.

OpenJDK Java 21 full runtime environment installed. I have tried uninstalling ttwatch and modifying udev rules back and forth with various alternatives, rebooting system, running as both user and root and also tried the Zadig WinUSB driver in Windows 11 but no luck, I get the same error message in Windows even after installing the Zadig driver according to instructions found here:

I never tried running TomTomWatch on Windows before I started using it on Arch-linux so it was first after the problem arose on linux that I also tried to run TomTomWatch on Windows.

The command: ttwatch --initial-setup is supposed to create a default XML preferences file on the watch, don't know if running this command might have something to do with this issue. I cannot see any XML preference file on the watch when mounted though:

I wrote a new udev rule, 99-driver-prevent.rules. (Directory /usr/lib/udev/rules.d/).

99-driver-prevent.rules:

SUBSYSTEMS=="pci", DRIVERS=="xhci_hcd", ATTRS{subsystem_device}=="0x1b21", ATTRS{subsystem_vendor}=="0x1043", ACTION=="add", ATTR{authorized}="0"

My 99-tomtom.rules:

SUBSYSTEM=="usb", ATTR{idVendor}=="1390", ATTR{idProduct}=="7475", SYMLINK+="tomtom", GROUP="users", MODE="0666"

After adding the new udev rule, I can see that the watch is detected when using TomTomWatch, with the correct serial no. HL4486G01240 showing up and the message "ERROR: USB Error: An interface is already claimed" doesn't show up anymore but it seems as other features as showing activity summary, activity history, show tracked activity etc. is not working so I guess the software now, after adding the new udev rule, is unable to read information from the watch, I can see the following error message when running TomTomWatch from a terminal:

Exception in thread "Thread-31" java.lang.NullPointerException: Cannot invoke "javax.usb.UsbInterface.getUsbEndpoint(byte)" because "this.iface" is null at net.studioblueplanet.usb.UsbConnection.sendRequest(UsbConnection.java:438) at net.studioblueplanet.usb.UsbInterface.getWatchTime(UsbInterface.java:965) at net.studioblueplanet.tomtomwatch.CommunicationProcess.getWatchTime(CommunicationProcess.java:905) at net.studioblueplanet.tomtomwatch.CommunicationProcess.lambda$pushCommand$1(CommunicationProcess.java:161) at net.studioblueplanet.generics.SerialExecutor.lambda$execute$0(SerialExecutor.java:55) at java.base/java.lang.Thread.run(Thread.java:1583)

I have to disable the 99-driver-prevent.rules if using ttwatch, otherwise the software won't work.

This problem is really hard to solve. I don't even know how to clean my system from all the ttwatch stuff

It is very strange indeed, because I know the software TomTomWatch was recognizing the watch correctly before i tried ttwatch. It was the first time i tried TomTomWatch though since I didn't have the need to use it before the discontinuation of TomTom's online service and software so unfortunately I haven't been able to use the software fully, uploading activities etc. I am using AUR packages on my system since I run Arch-linux and the process of uninstalling an AUR package should remove everything from the system so for me this is confusing. Could there still be something left that conflicts? By the way, I am using an ASUS laptop with several usb ports, some usb 2.0 and one usb 3.0, I have tried all of them, same result. I wonder if ttwatch modifies anything on tthe watch itself, after running the command ttwatch --initial-setup, but from what I can see when looking at the files that are on the watch, nothing seems to be changed.

I haven't pinned down the exact configuration, but in this block, I did the following just now:

• Added a watch name
• Added <ephemerisModified>0</ephemerisModified>
• Deleted all but the ConfigURL

Then I recompiled and ran ttwatch --initial-setup again, and things appeared to start working in TomTomWatch: https://github.com/ryanbinns/ttwatch/blob/b95fd2c3bfa2dfa95e406f4c360ada9c14af7451/src/libttwatch.cpp#L924-L936

So for me it did seem to be something related to that preferences file (and it could be something as simple as just the watch name, but I haven't tested bringing back the other configurations yet to see...)
