From 97cd49ebf74e3bee49d541a47ef085df1fbfac7d Mon Sep 17 00:00:00 2001 From: Stepan Moskovchenko Date: Wed, 9 May 2007 14:53:04 -0400 Subject: [PATCH] USB: ftdi_sio.c: Allow setting latency timer on FT232RL The new FT232RL allows setting and getting the value of the latency timer, like on the FT232BM. However, the driver will not create the sysfs entries for the RL without this one-line patch. I have tested it on two systems with successful results.
