From 49bb607fa0bd94e4855ee695f9ed3ecee7579cc6 Mon Sep 17 00:00:00 2001 From: Jeremy Katz Date: Tue, 19 Jun 2007 17:15:38 -0400 Subject: [PATCH] USB: Support Blackberry Pearl with berry_charge The Blackberry Pearl (8100) needs similar tweaks as older Blackberry models to be able to charge when connected via USB. The Pearl also adds an additional need to go into a separate mode for fully accessing the device; do that by default as well.
