[linux-usb-devel] [PATCH] usb: extract sensible strings from buggy string descriptors

-------------------------------------------------------------------------

From: Duncan Sands
Subject: [linux-usb-devel] [PATCH] usb: extract sensible strings from buggy string descriptors
Date: Fri, 24 Sep 2004 02:21:22 -0700

--------------------------------------------------------------------------------
The Freebox is a USB modem popular in France. It returns bogus string
descriptors: while the string part is there, the length and type bytes
are both zero. This patch detects that case and tries to recover a
sensible string by scanning for printable Latin characters. This not
only causes the modem to spring to life (because usbnet gets a valid
MAC address) - it also means you get the correct Product and Manufacturer
strings in sysfs and elsewhere. This patch is in the "mostly harmless"
category.
