"Failed to find valid endpoints!" issue

[sandeshworld]

Description

I can see that Thor is detecting the usb device but when I select the samsung device I get the error:

Reproduction

1. ./TheAirBlow.Thor.Shell/bin/Debug/net7.0/TheAirBlow.Thor.Shell
2. connect
3. Select the samsung device (it is in ODIN mode - albeit with a BOOT Load Fail error)

Expected behaviour

I expected it to connect. I also followed the steps:
"~~~~~~~~ Platform specific notes ~~~~~~~~
You have to run Thor as root or edit udev rules as follows:

1. create and open /etc/udev/rules.d/51-android.rules in an editor
2. enter SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="YourUserGroupHere"
   Additionally, you may have to disable the cdc_acm kernel module:
3. To temporarily unload, run "sudo modprobe -r cdc_acm"
4. To disable it, run "echo 'blacklist cdc_acm' | sudo tee -a /etc/modprobe.d/cdc_acm-blacklist.conf""
   just in case.

Hardware and software

Host: Ubuntu22.04, amd64
Device: Samsung Nav Tab Active3

dotnet --list-runtimes
Microsoft.AspNetCore.App 7.0.9 [/usr/lib/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 7.0.9 [/usr/lib/dotnet/shared/Microsoft.NETCore.App]

dotnet --list-sdks
7.0.109 [/usr/lib/dotnet/sdk]

Additional context

The ODIN desktop app is able to connect fine...

[TheAirBlow]

You should have made a protocol bug report... Anyway, do the same thing but with debug on beforehand.

[sandeshworld]

Great. Will try that. Thank you

It's probably cdc_acm interfering, Thor tells you what to do to get rid of it.
If that doesn't help, send the /dev/bus/usb/AAA/BBB file. To get AAA and BBB, do the following:

1. Connect the device in download mode to your computer and run lsusb
2. Find the line with your Samsung phone, and here's Bus AAA Device BBB

Hey, same issue. I haven't done anything related to Samsung with my Linux machine before, but I followed all the steps on Arch Linux and got this:

Run lsusb with the device connected, you'll get something like this:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Then upload the file called /dev/bus/usb/BUS/DEV, where BUS and DEV correspond to Bus BUS Device DEV of your Samsung device

Try to use an USB-A to USB-C cable, this resolves it for me.

Was just running into this same issue on v1.1.0.

Welcome to Thor Shell v1.1.0!

I used a USB A-to-C cable, ran modprobe -r cdc_acm as root beforehand, and ran Thor as root as well. Still no luck though.
