Hi all! And Happy New Year to everyone!
3 days ago I faced the problem which I could not solve using Google. Currently I work on board with PXA255, kernel 2.6.10, and I need the ability to access the board through USB from both Linux and Windows hosts. I built the kernel with USB Gadget support for PXA2xx (in kernel) and File-backed Storage Gadget (as a module). Then I created the storage file on the partition with YAFFS (mounted to /app). # dd if=/dev/zero of=/app/file_storage bs=1k count=10000 # insmod g_file_storage.ko file=/app/file_storage Next I connected my board to the Linux host and created the DOS partition with 'fdisk /dev/uba' command. Due to mkdosfs does not work with USB directly (it failed with " unable to get drive geometry for '/dev/uba1' "), I did following: # cat /dev/uba1 > tmp_file # mkdosfs tmp_file # cat tmp_file > /dev/uba1 # mount -t msdos /dev/uba1 /mnt/usb After that my board works fine as a mass storage device with Linux host. But I have problem with connecting to Windows hosts (I tryed to connect my board to the host with Windows XP Pro SP1). After plugin the cable I can see many messages in the board console: ........ udc: USB reset udc: USB reset g_file_storage gadget: full speed config #1 udc: USB reset udc: USB reset g_file_storage gadget: full speed config #1 ... and so on. Sometimes, after about 3...5 minutes of waiting, it connects and WinXP opens a folder with the flash contens, sometimes not. But all this time WinXP shows that Flash Mass Storage device driver works correctly. I enabled debugging info in file_storage.c and here is the output of dmesg during the Windows connection: ---------------------------------------------------------------------------------

a newcomer in USB :( Could somebody be so kind to point me what I did wrong?
