From aa0850e1d56623845b46350ffd971afa9241886d Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Mon, 26 Oct 2015 18:58:14 -0200 Subject: [PATCH] [media] airspy: increase USB control message buffer size Driver requested device firmware version string during probe using only 24 byte long buffer. That buffer is too small for newer firmware versions, which causes device firmware hang - device stops responding to any commands after that. Increase buffer size to 128 which should be enough for any current and future version strings.
