Проблема при загрузке с USB флешки

Добрый день. Есть необходимость загрузить QNX 6.5.0 c флешки.
- флешь накопитель Verbatim на чипе SM3255AA , память Samsung K9LCG08U1M, VID = 090C PID = 1000
- Материнская плата Advantec AIMB-785
Режим работы USB накопителя переведен в режим USB-HDD.
С помощью fdisk-a создан раздел QNX6(179)+Boot+Loader. Отформатирован и скопированы все файли для успешного запуска.
При загрузке выдает сообщение:

Цитировать

Unable to mount a qnx6 filesystem as /fs/hd10-qnx on /dev/hd10t179 (Read only file system)

Я так понимаю, что devb-eide не может корректно работать с massStorage.
Под самой же QNX, если флешку "скормить" devb-umass, то все хорошо монтируется.
Пересобирал ifs c "наглым" запуском devb-umass для флехи, но не помогло.
Код прилагаю:

Подскажите, пожалуйста, куда копать?
