[SLUG] mouse driver

[henry]

Dear Sirs:     I use "ls -l /dev/mouse" ,           I get "                5                 Jan 3 2002            mouse->psaux" There is Minor_ID (5), but no Major_ID .(it's supposed to appear in front of Minor_ID(5) )   I want to link mouse to another device(say USB mouse instead of ps2 mouse ), But after removing the link (mouse) I found that I cant         "mknod  mouse  c  NULL 5 "     .(I try use NULL as Major_ID,but shell said it's illeagal.)   BestRegards Henry
