Well overall its an extensive list.
SNES - you have things like the super gameboy and multitap
Gen - Sega CD though really an add-on than accessory
PS2 - racing wheel
PC - console controller converter
Wii - Wii Speak, perfect shot, 2 classic controllers (soon to be 3 with only 2 Wii remotes lol), Balance Board, Guitar, drums, looking into the 1080p upscaler next
360 - headset
PS3 - PS eye, MGS headset
Xbox - Pump it up pad
GC - DDR pad
N64 - Hey you pikachu mic
NES - lightgun
GB - link cables out the wazoo, magnifiers, external lights
GBA - recharge kit
DS - Sword stylus/keychain, Max Media Dock
PSP - Batman (the Joker) skin, improved thumb stick
So really the only console I didn't own accessories on would be the PS1... amazing unless gameshark counts then I had one for just about every console since the GB.
