In case your bootloader can take that decision (eg. if the device is present at boot time, and the bootloader has the proper probing logic or simply knows the device has to be there), that would be an pretty easy way. But let me add another usecase, which might be a bit more tricky: Let's assume we can plug in some more complex device, which consists of several (pretty standard) subdevices, behind certain bus'es (maybe it's attached via USB, and somewhere behind are some I2C bus'es with regulators, pwm-generators, etc). Let's further assume, we already got some DTS or some piece of memory with an DTB subtree for that device (eg. some simple bulk endpoint that just gives back a bunch of bytes with the DTB). Now, when the device is plugged in, I'd like to get that piece of DTB loaded and the corresponding drivers initialized. And, of course, when it's plugged-out, everything should be shut down cleanly. How could we achieve that ? --mtx -- Enrico Weigelt, metux IT consult +49-151-27565287 MELAG Medizintechnik oHG Sitz Berlin Registergericht AG Charlottenburg HRA 21333 B Wichtiger Hinweis: Diese Nachricht kann vertrauliche oder nur für einen begrenzten Personenkreis bestimmte Informationen enthalten.
