What is the correct syntax for using gdb with termux-usb?

Question

I am writing a program in C using the libusb library, to enable an Android phone to communicate with a USB device.

The C program runs in the termux emulator on the phone. It uses termux-usb to make the usb device visible to the C program as follows:

>termux-usb -l
>termux-usb -r /dev/bus/usb/001/002
>termux-usb -e ./program /dev/bus/usb/001/002

What is the correct syntax to use if I want to run and debug the program using gdb together with termux-usb?

I've tried all kinds of combinations of gdb --args and termux-usb -e, but none recognize the /dev/bus/usb/001/002 argument.

Answer 1

maybe: gdb | termux-usb or termux-usb | gdb like, If you run curl with just url and no args, it will write to terminal, but If you run curl [url] | cat < a, it will write to the file "a"
