Dear Engineers,

 When I use the g_file_strogae.ko module, I failed to write big file to
 the disk.
 Hardware platform:
 CPU: ARM926T
 SDRAM: 32M sdram
 Kernel:2.6.19.  patch


 I plug a 512MBytes usb flashdisk(fat32 type) into the board usb host
 interface, and connect a usb line between the board usb device interface
and a PC with WinXP OS.
 In the board side, I use the following command:
 #> insmod ./g_file_storage.ko file=/fat.fs removable=y
 where /fat.fs is the external 512MB flash disk.
 Then in the PC side, XP can recognize the board as a usb mass storage
 device. And read big file(3Mkbytes) is OK.
 But when I write a big file(above 30kbytes) into the board from XP side, the
 speed is very slow and finally failed. (Write a 30KBytes file is OK). In
 the board side, kernel repeatedly printed following message every
 several seconds. "g_file_storage gadget: full speed config #1".
 What's wrong with it? and i have face i/o device error when writing the big file.
please can you help me.

Thanks & Regards,
A.PERIYANAYAKI
