+ Originally, this driver used scsi pass through commands, which required the
+ usb-storage module to be loaded, providing the /dev/sgX links. The USB mass
+ storage implementation on the STLinkv1 is however terribly broken, and it can
+ take many minutes for the kernel to give up.
+
+ However, in Nov 2011, the scsi pass through was replaced by raw libusb, so
+ instead of having to let usb-storage struggle with the device, and also greatly
+ limiting the portability of the driver, you can now tell usb-storage to simply
+ ignore this device completely.
