My problem is: I need to find a way to tell Linux not to load the usb-storage module when a certain peripheral, whose signature I know, is inserted. For now the only way I have found is putting usb-storage in the blacklist but this means module doesn't load when I plug my usb key or my external hard drive so I look for something finer grained Details I own a cell phones who han USB connector and can be accessed either as an MTP device or as a mass storage one but the latter works if, and only if, it has an additional memory card inserted (presently I have none). The phone prompts for the mode at coonect time b ut no matter what I select the usb-storage loads itself, unsuccessfully tries to put the phone in storage mode (normal behaviour since the phone has no external memory card) and after a minute or two, gives up, unloads itself and removes the peripheral from the list of present USB devices. In other words even after the usb-storage module has unloaded I cannot use the phone in mtp mode.
