from the dump:

Jan 25 15:54:19 CST 2013 serial 213453 [jmk]
Jan 25 15:54:19 CST 2013 /n/sourcesdump/2013/0214/plan9/386/bin/usb/serial 213453 [jmk]
Dec 10 21:27:37 CST 2012 /n/sourcesdump/2013/0125/plan9/386/bin/usb/serial 211141 [sys]
…

the Dec 10 version works with Prolific USB-to-Serial devices.
The more recent one does not and ends up breaking on treeinsert:
