I have confirmed that at least on x86_64-linux (service usb-modeswitch-service-type) works with the default config and that (service usb-modeswitch-service-type (usb-modeswitch-configuration (config-file #f))) works, passing no config file, leading to different defaults. Manual use as described in a comment of the usb-modeswitch package works as well. I hope using putenv before wrap-program is OK. I tried using computed-file #:options instead, but could not get it to work. I am uncertain if having paragraphs like this in modem-manager-service-type and usb-modeswitch-service-type is a good idea: This service is part of ‘%desktop-services’ (*note Desktop Services::).
