Heimdall: ERROR: libusb error -7 whilst sending bulk transfer. Retrying

[Vatish Sharma]

I am using Heimdall v1.4.2. I have compiled it from the source code.

I have run the `heimdall detect` and `heimdall print-pit --verbose`.

My device is successfully detected by the Heimdall but the second command failed. I am using Samsung S10 5G device(Qualcomm). Following are the logs:

```
heimdall print-pit --verbose

I have read another similar issues and tried following things:

1. Tried different cables (Type-C to Type-C, Type-C to USB)
2. Tried different ports.
3. Plug-Unplug cable before run command.
4. Reboot the machine after Heimdall source code compilation.
5. `sudo apt update && sudo apt upgrade`.
6. Below is the `libusb` detail:
```

Please suggest how can I resolve this issue.

I moved this from the Galaxy S forum (for the ancient original Galaxy S phone) to the S10 forum for more appropriate traffic.
