This seems to be a really nice way... For my device disabling the cd-drive works very well.. but i got some response from a guy that he only gets one tty-device.. maybe this can fix this problem...
it also seems the content of the cd-image is not the same on all devices.. my (branded) device does not contain any manual, numbers, oder something else... only a strange proprietary tool to dial in.... so if i understand right the patch to unusual_devs.h is removed and the one to the option-driver remains... seems to be a good solution.. will test it next week... 73 Zitat von Rui Santos <[EMAIL PROTECTED]>: > Hi All, > > IMHO, this patch should be removed...
