From cffcc503580907d733e694d505e12ff6ec6c679a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Fri, 10 Aug 2012 18:26:50 +0200 Subject: [PATCH] usb_storage: Restore non-EHCI support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The commit 5dd95cf made the MSC driver EHCI-specific. This patch restores a basic support of non-EHCI HCDs, like before that commit. The fallback transfer size is certainly not optimal, but at least it should work like before.
