It's not _all_ of USB, just:

166 char ACM USB modems
0 = /dev/ttyACM0 First ACM modem
1 = /dev/ttyACM1 Second ACM modem
...

167 char ACM USB modems - alternate devices
0 = /dev/cuacm0 Callout device for ttyACM0
1 = /dev/cuacm1 Callout device for ttyACM1
...

188 char USB serial converters
0 = /dev/ttyUSB0 First USB serial converter
1 = /dev/ttyUSB1 Second USB serial converter
...

189 char USB serial converters - alternate devices
0 = /dev/cuusb0 Callout device for ttyUSB0
1 = /dev/cuusb1 Callout device for ttyUSB1
...

216 char USB BlueTooth devices
0 = /dev/ttyUB0 First USB BlueTooth device
1 = /dev/ttyUB1 Second USB BlueTooth device
...

217 char USB BlueTooth devices (alternate devices)
0 = /dev/cuub0 Callout device for ttyUB0
1 = /dev/cuub1 Callout device for ttyUB1
...

I think you were confused with char major 180 which has
printers/mice/scanners/etc on it.
