 +
 +This device is recognised as a mass storage device which doesn't actually work.
 +
 +In Linux add this on the RPi to /boot/cmdline.txt and reboot.
 +
 +<code>
 +usb-storage.quirks=483:3744:i,483:374b:i,483:374e:i
 +</code>
 +
 +With ARMBIAN, update /boot/armbianEnv.txt and reboot.
 +
 +<code>
 +usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u,0x0483:0x3744:i,0x0483:0x374b:i,0x0483:0x374e:i
 +</code>
 +
 +Similar modprobe options are used if mass storage is a module.
 +
 +<code>
 +options usb-storage quirks=483:3744:i,483:374b:i,483:374e:i
 +</code>
 +
 +When the device is plugged in, something like this is logged:
 +
 +<code>
 +usb-storage 1-1.2.1:1.0: USB Mass Storage device detected
 +usb-storage 1-1.2.1:1.0: device ignored
 +</code>
 +
 +This will stop mass storage using the device, however, it
 +doesn't mean it will function correctly and will take
 +a number of probes until it operates and may never work.
 +
 +A solution is as follows
 +<code>
 +#! /bin/sh
 +#
 +# ON DEVICE ERROR
 +# RUN THIS SCRIPT
 +# UNPLUG STM32 VL Discovery
 +# PLUG IN STM32 VL Discovery
 +# CTRL-C
 +#
 +while test 1; do
 +        openocd -f "interface/stlink.cfg" -c "transport select hla_swd" -f "target/stm32f1x.cfg"
 +        sleep 0.1
 +done
 +</code>
 +
 +===Clocks===
 +
 +<code>
 +HSE 8000000 X2 ESA8.00000F20D25F
 +HSI 8000000
 +LSE 32768   X3 MC306-G-06Q-32.768
