There's no way to tell what's going wrong without more information. You should turn on USB Mass-Storage verbose debugging in the kernel configuration (CONFIG_USB_STORAGE_DEBUG). That will cause a lot of extra debugging info to appear in the system log. If it's at all possible for you to use a 2.6 kernel instead of 2.4, you should do so.
