+Subject: [PATCH] linux_usbfs: Fix parsing of descriptors for
+ multi-configuration devices
+
+Commit e2be556bd2 ("linux_usbfs: Parse config descriptors during device
+initialization") introduced a regression for devices with multiple
+configurations. The logic that verifies the reported length of the
+configuration descriptors failed to count the length of the
+configuration descriptor itself and would truncate the actual length by
+9 bytes, leading to a parsing error for subsequent descriptors.
+
+Closes #825
