Dotaz: udev, mass storage, rozne spravanie

[Balu]

Dobre rano prajem.
Natrafil som na mensi problem s USB mass storage zariadenim. Ked pripojim USB kluc (Apacer 256MB USB 2.0), okamzite mi najde a vytvori vsetky potrebne /dev subory (sdX, sdX1, sg0) a mozem mountovat. Ked vsak pripojim digitalny fotoaparat (Panasonic FZ10, 128MB SD SanDisk, USB1.1), vytvori mi iba sdX a sg0. sdX1 mi vytvori az nasledne po fdisk -l /dev/sdX . Az po tom mozem mountovat. Sksual som prehrabat vsetky mozne konfiguraky udev, ale nic rozumne som nenasiel (alebo si len nevsimol). Divne mi pripada to odlisne spravanie sa zariadeni, rozum hovori ze mass storage je mass storage a ma sa spravat vzdy rovnako. Ma niekto nejaky napda, co s tym?

Nenapada ma co este by som uviedol, ak ma niekto nejaku myslienku, skuste poradit. Dakujem.

Je mi to opravdu divné, jediné co mně napadá (a tebe už asi taky napadlo)je nakonfiguraovat hotplug/udev tak aby po připojení foťáku provedl fdisk -l ...

[Balu]

No hej, napadlo ma to, ale je to skrabanie sa lavou zadnou za pravym uchom, chcelo by to nejake elegantnejsie riesenie. Pokial nikoho nic nenapadne, tak sa asi budem vrtat tymto smerom.

mass storage by se chovalo standardne, kdyby vyrobci ten standard dodrzovali. Nekteri se neobtezuji na klicenkach ani vytvorit oddil, o fotakach vubec nemluve.

Problem bude podla vsetkeho v jadre. Na tejto diskusii sa to riesi.
