Hi

I have downloaded the STM32_USB-Host-Device _lib_V2.0 library for USB Mass storage Application.I have taken the mass storage example and compiled  for my board(STM32f217). But when I connect my pendrive to the board and during debugging it is frequently coming to the HOST_ERROR_STATE and the device is not getting connected.Iam using On chip full speed phy.Can anyone tell the steps of initialization. #stm32f217-usb-mass-storage

I seem to recall hear other complaints like this on the forum, but can't dig out any specific cites right now.

The implementation is sensitive to low quality flash drives without crystals and operating outside the USB specs. One of the better USB MSC Host examples is the Firmware Upgrade example for the Discovery F4 boards, and which should be relatively portable. The USB v2.1.0 library?
