Имеем
- Ubuntu 14.04 32bit
- STM32VLDISCOVERY
- STM32F107VC
- OpenOCD 0.8.0
- arm-none-eabi-xxx
В качестве отладчика пытаюсь запустить discovery. Пока что все попытки не увенчались успехом.
при подключении discovery ядро (dmesg) выдает:

IF YOU HAVE AN STLINKv1
~~~~~~~~~~~~~~~~~~~~~~~
The STLINKv1's SCSI emulation is very broken, so the best thing to do
is tell your operating system to completely ignore it.
Options (do one of these before you plug it in)
*) modprobe -r usb-storage && modprobe usb-storage quirks=483:3744:i
or *)1. add "options usb-storage quirks=483:3744:i" to /etc/modprobe.conf
*)2. modprobe -r usb-storage && modprobe usb-storage
or *)1. cp stlink_v1.modprobe.conf /etc/modprobe.d
*)2. modprobe -r usb-storage && modprobe usb-storage

stlink_usb: Fix swallowed error on read/write operations, add retries on SWD WAIT, clean up error debug output.
- stlink_usb_get_rw_status() had a bug where FAULT or WAIT responses
in read/write operations were ignored, leading to incomplete data.
- Added wrapper stlink_cmd_allow_retry to handle
SWD_AP_WAIT/SWD_DP_WAIT statuses in most commands. These statuses
appear if an SWD read or write received a WAIT ACK response from the
target more than 4 times in a row. The driver retries the operation
(with exponential backoff) before failing outright (in testing 1
retry was always enough.)
- As part of the implementation of stlink_cmd_allow_retry a large
number of lines of boilerplate were refactored.
- Fleshed out stlink_usb_error_check and added it to some more code
paths so WAIT or FAULT responses are logged to debug. WAIT responses
will be logged even if they are subsequently retried, which should
help in case the retries have subtle side effects (none
anticipated.)
Tested with two targets: STLINK F0 Discovery, Nordic NRF51822. Only
tested with STLINK V2 programmers.
Но даже откомпилированая последняя версия openocd выдает:

Как я понял, ребята успешно запускали OpenOCD на STLINK V1
Может я что-то упустил, в чем может быть причина того что OpenOCD не стартует ?
P.S. Spoiler работает не совсм коректно...
Add #1
======================
The discovery’s stlink (both st8, st32) implementation of the USB protocol violates the USB standard in multiple ways and it's too much broken for the linux kernel driver. Although it's possible to intercept the core and write/read a data in some for that designated SRAM region, there isn't any direct communication channel to the chip over the USB. The right (but long term) solution will be to replace the stlink firmware.
