[SOLVED] firmware from USB stick during install

view story

http://crunchbanglinux.org – greetings!i'm currently installing #!11 on a laptop. there is a firmware file which is required, and the installation gives me a window saying to insert removable media containing the file (it also says that media can be CD, floppy, or USB stick).when i insert a USB stick which has the file on it and hit "continue", the installation just cycles back to the message window described above, without mounting the USB stick and reading the file.do i need to manually mount the stick or something?this is not a big deal, since i know i can add that file post-install... mostly i'm br (HowTos)
