I have added module parameters to the functionfs module in the kernel commandline. I used escaped quotes surrounding the Strings that have space. This is my commandline: mem=128M console=ttyS0,115200 mtdparts=atmel_nand:256k(bootstrap),256k(bootvar),256k(envvar),256k(dtb0),3M(kernel0),55M(rootfs0),256k(dtb1),3M(kernel1),55M(rootfs1),11008k(userfs),-(reserved) rootfstype=ubifs ubi.mtd=5 root=ubi0:rootfs lpj=1314816 quiet g_ffs.idVendor=8022 g_ffs.idProduct=26 g_ffs.bcdDevice=512 g_ffs.iManufacturer="This string does not work" g_ffs.iProduct="this one neither" g_ffs.iSerialNumber=123456789 g_ffs.bDeviceClass=255 The strings that are diplayed are: for iManufacturer: "This iProduct="This" for iProduct: "USB Function Filesystem" Without the spaces it works. I have 1kb for the command line. All I did was add the epo polling to f_fs.c. Could this have caused the behaviour? -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
