Subject: [U-Boot-Users] [PATCH] ISP116x: delay for crappy USB keys.
Date: Tue, 24 Apr 2007 15:40:10 +0200 [thread overview]
Message-ID: <20070424134010.GH9973@enneenne.com> (raw)
ISP116x: delay for crappy USB keys.
Using some (very) slow USB keys cause the USB host controller buffers
are not ready to be read by the CPU so we need an extra delay before
reading the USB storage data.
