Ability to flash multiple teensys?

[mgcrea]

I have an Ubuntu box with 5 teensy boards connected, I'm trying to flash them with an .hex file, but it looks like I can only flash a single one. Any idea on how to solve that? Would it be possible to add an optionnal parameter to select the device?

You could try adding this to the soft reboot code. But how to distinguish which device? I can't get involved in this.

I'll try to find something, thanks.

I think there might be something to do in open_usb_device with libusb_get_string_descriptor_ascii to retrieve and filter by serialNumber.

Here is the output with debug enabled:
