Hi, i still try hard to get my mouse running, but until now, no chance. I looked at my .config from the actual Kernel. I remembered that i read somewhere, that ACPI should be deactivated by default on Fedora. Seems that i misread this, as my .config sys acpi=y. Could it be an issue, that acpi somehow blocks my usb-hid-mouse? How can i deactivate acpi permanently without recompiling the whole kernel? is it sufficient to insert acpi=off in the grub.conf? thx in advance Roger btw. thx to Alexander didn't remark just taking one recipient instead of the list....
