After moving the devices you specified from "Management" to their
correct category, all the remaining devices were usb, so I renamed
the category to USB (Management is empty, so removed) 
Regarding the ISA devices, I spread them between categories:
name "isa-ide", bus ISA, categories "Storage"
name "ne2k_isa", bus ISA, categories "Network"
name "isa-parallel", bus ISA, categories "Input"
name "isa-serial", bus ISA, categories "Input"
name "isa-cirrus-vga", bus ISA, categories "Display"
name "isa-vga", bus ISA, categories "Display"
name "isa-applesmc", bus ISA, categories "Misc"
name "isa-debugcon", bus ISA, categories "Misc"
name "isa-debug-exit", bus ISA, categories "Misc"
Regarding the I2C device, I moved it to the misc Category, I
was misled by the name. Thanks

As mentioned above , the "Management" category disappear, so Assembly
includes should be now controller/hub/bridge

I'll release a version soon.
Thanks!
