After jump to DFU Bootloader Device resets on DFU command

[pmark]

I use JumpToBootloader() to jump to bootloader, device enters bootloader and shows device

i then send it this command

dfu-util -d 0483:df11 -S 305737513432 -a 0 -s 0x08000000:leave -D fw.bin

and device resets 

Erase [ ] 0% 0 bytesdfu-util: Error during special command "ERASE_PAGE" get_status: -9 (LIBUSB_ERROR_PIPE)

If i enter the bootloader via the BOOT pin it works fine

It is like something else needs to be reset ?

dfu-util 0.11-dev
