Subject: USB: option Add blacklist for ZTE K3765-Z (19d2:2002)
From: Torsten Hilbrich <[email protected]>
commit 7e8e62e4a5d26e4cb45f25dddd093837d75616c2 upstream.
The funtion option_send_status times out when sending USB messages
to the interfaces 0, 1, and 2 of this UMTS stick. This results in a
5s timeout in the function causing other tty operations to feel very
sluggish.
This patch adds a blacklist entry for these 3 interfaces on the ZTE
K3765-Z device.
I was also able to reproduce the problem with v2.6.38 and v2.6.39.
This is very similar to a problem fixed in
commit 7a89e4cb9cdaba92f5fbc509945cf4e3c48db4e2
