[Qemu-devel] [PATCH 2/3] ohci: fix Host Controller USBRESET


From: Hervé Poussineau
Subject: [Qemu-devel] [PATCH 2/3] ohci: fix Host Controller USBRESET
Date: Sun, 20 Dec 2015 00:23:50 +0100

Specification says that, when entering this state, "the contents of the 
registers
(except Root Hub registers) are preserved by the HC. [...] The Root Hub is 
being reset,
which causes the Root Hub's downstream ports to be reset and possibly powered 
off."
