Hi, everyone I wish to use my embedded system as USB storage gardget. I installed module g_file_storage as follows : #insmod g_file_storage file=/dev/mtdblock5 mtdblock5 is NAND flash JFF2 file system (root file system of my device) but in windows or linux pc, I cannot see the USB storage device above. The following message appear periodically : g_file_storage gadget : full speed config #1 When I "cat /proc/bus/usb/device", the device is shown as follows : T: Bus=01 Lev=01 Prnt=01 Port=03 Cnt=01 Dev#= 3 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=0525 ProdID=a4a5 Rev= 3.13 S: Manufacturer=Linux 2.6.27 with at91_udc S: Product=File-backed Storage Gadget S: SerialNumber=372041756775 C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 2mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.)
