Hi. I'm trying at91_udc driver with g_file_storage on AT91SAM9260-EK board. I'm using kernel 2.6.24 and 2.6.22(+at91-exp.patch).
When I load the g_file_storage module, host can detect storage device soon, but take few _minutes_ to detect its partition table. This storage image file works fine with another udc driver on another platform. So I don't think it is a image problem or host side (or cable) problem. Has anyone seen problem like this? Here is an UDC side log: # modprobe g_file_storage file=/fatimage udc: at91_udc version 3 May 2006 g_file_storage gadget: File-backed Storage Gadget, version: 7 August 2007 g_file_storage gadget: Number of LUNs=1 g_file_storage gadget-lun0: ro=0, file: /fatimage g_file_storage gadget: full speed config #1 ...
