Subject: [PATCH 3/6] gspca - gl860: USB control message delay unification
Date: Wed, 02 Jun 2010 00:57:48 +0200 [thread overview]
Message-ID: <1275433068.20756.101.camel@miniol> (raw)
gspca - gl860: USB control message delay unification
From: Olivier Lorin <o.lorin@laposte.net>
- 1 ms "msleep" applied to each sensor after USB control data exchange
This was done for two sensors because these exchanges were known to
be too quick depending on laptop model.
It is fairly logical to apply this delay to each sensor
in order to prevent from having errors with untested hardwares.
Priority: normal
