Hi Engineers,

              Dear all:

 When I use the g_file_strogae.ko module, I failed to write big file to

 the disk.

 Hardware platform:

 CPU: S3C2440A

 SDRAM: 32M sdram

 Kernel:2.6.19 
 processor:AT91SAM9261
 
 I plug a 256MBytes 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=/dev/sda removable=1

 where /dev/sda is the external 256MB flash disk.

 Then in the PC side, XP can recognize the board as a usb mass storage

 device. And read big file(3Mbytes) is OK.

 But when I write a big file(3Mbytes) into the board from XP side, the

 speed is very slow and finally failed. (Write a 3KBytes 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?


Regards,

M.Maheswaran
