Hello everyone!

I want to create a new topic for incremental learning with usb for beginners. I've started to learn usb library, seen examples, but I have many questions. First of all, I can't undestand, how to configure pins VBUS, ID, DP,DM fot host.

Use the Host example directly. The USB library has example for Host-HID and Mass-Storage.

See for UM1021(

I try efsl using example from st stm32f105_107_usb_fw. When I use usb flash storage 16 Gb capacity I had problems with efsl initialization bacause of fs_varifySanity returns 0 (BytesPerSector>512). When I try mobile phone sd card (2Gb capasity) with FAT I have succeed. When I make partitions on flash, one partition is 2Gb capacity, and formate it with FAT or  FAT32 I have fs_varifySanity=0 because of SectorsPerClaster=128(supported only 2,4,6,8,16,32,64). When I make partition 1Gb capacity on usb flash storage, formatted with FAT or FAT32 I have succeed.  Where is problem? What can I do to use any usb flash storage with any capacity?

Can anybody help me?

Probably not a lot. The USB and SD examples posted by ST pass addresses as 32-bit values, you'll clearly have problems with media >4GB in these situations. It is important to use BLOCK NUMBERS and not OFFSET ADDRESSES. I've posted a fixed version of the SD/MSC code for the STM32F4-Discovery board. Suggest you review that.
