-Subject: [PATCH 046/114] fiq_fsm: Implement hack for Split Interrupt
- transactions
-
-Hubs aren't too picky about which endpoint we send Control type split
-transactions to. By treating Interrupt transfers as Control, it is
-possible to use the non-periodic queue in the OTG core as well as the
-non-periodic FIFOs in the hub itself. This massively reduces the
-microframe exclusivity/contention that periodic split transactions
-otherwise have to enforce.
-
-It goes without saying that this is a fairly egregious USB specification
-violation, but it works.
-
-Original idea by Hans Petter Selasky @ FreeBSD.org.
