That cannot happen. A single instance of mass_storage cannot¹ be added twice to the same configuration. ¹ To be more precise, not via configfs. A legacy gadget could do that, but that would be a bug in that legacy driver, not f_mass_storage. Moreover, no current legacy gadgets do that though so IMO this is an academic discussion. -- Best regards ミハウ “𝓶𝓲𝓷𝓪86” ナザレヴイツ «If at first you don’t succeed, give up skydiving»
