When I put off my floppy-device (/dev/fd1) and put in my cdrom-device (/dev/hdc; both no pcmcia-devices) or vice versa, the kernel doesn't recognize this change. The change - LED of the laptop is blinking until I suspend the laptop for example with apm -s or with the keyboard Fn-F4 and rewake it. After this "little sleep", the kernel suddenly knows about the new hardware and it can handle it. I tested the hotplugging-feature of the kernel 2.4.x - but I couldn't get it working. Is there any other possibility to give the kernel a chance to detect a hardware change without going through the suspend-mode? I mean, is there a piece of software, which does the same as in the wake-up-situation of the notebook after suspend? Thank you for your advice, Andreas Hartmann
