From 2cbd3f5ccd43ba823e183f98a798d4b23cfb12b8 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 3 Nov 2014 05:16:07 +0100 Subject: [PATCH] Bluetooth: btusb: Add internal callback for USB bulk rx data Some vendors require special handling of the rx data from the USB bulk endpoints. For that case provide an internal callback that can overwrite it with a custom receive function.
