    mounting sandisk sd card within mp3 player


    I know I made this thread already, but I did not get answer so I am going to try one more time. I have a Lyra RCA RD1071A 182mb MP3 player, and it has a slot for a sd card. I have an sandisk SD 128mb card that I have in it, and when I used FC2, I was able to mount it as sdb1, while the mp3 player itself mounted as sda1. Since I upgraded, FC3 does not even detect the card. Can somebody help me? I really don't want to have to buy a card reader if I don't have to.... (yes, i typed dmesg and yatta yatta, no such sdb1 device, as it says when I try to mount it).

    Lets start off my seeing the contents of an "lsmod" to tell us what modules are loaded, andy maybe you could try and pinpoint if any of your kernel options around USB have changed between FC2 and FC3.

    well, i have no way of telling what usb features changed between FC2 and FC3 for 2 reasons. one, my cousin compiled me a custom kernel in FC2. secondly, my hdd crashed so even if i didn't reinstall FC3 on that hdd, i would have no access to the configuration. also, i found an option in the kernel called "low performance USB Block driver" which is supposed to make USB flash cards more compatable or whatever, but it gave me a warning: enabling this cripples the usb-storage driver. should i try enabling this? at any rate, here are the mods i have.

    the mods:

    Is that what lsmod says when you have both of those devices plugged in?

    oh, no.... this is what it says with my mp3 player plugged in and my SD card plugged into my mp3 player:

    it looks the same to me though :-/

    Are there any entries in dmesg and/or /var/log/messages when you insert the devices? Does the "lsusb" command show anything while these things are inserted?

    [root@localhost ~]# lsusb
    Bus 005 Device 002: ID 069b:070f Thomson, Inc.
    Bus 005 Device 001: ID 0000:0000
    Bus 004 Device 001: ID 0000:0000
    Bus 003 Device 001: ID 0000:0000
    Bus 002 Device 001: ID 0000:0000
    Bus 001 Device 001: ID 0000:0000

    obviously it does not see the SD card I have inside my mp3player (Thomson is the manufacturer of my mp3 player). Any clues?

    Double check your USB options in the kernel. Ensure that usbcore, usbstorage, and the appropriate ehci/ohci, and uhci options are included. "lspci -v" (i think) should describe your USB subsystem and give you a clue as to which of ehci or ohci you should use.

    If they are all included in the kernel, you may have to try loading them as modules. Its a stretch, but I've noticed subtle differences in behaviour with some USB devices when compiled as a module as opposed to directly in the kernel.

    Found this link, which might have more info. Haven't dug into it much yet.

    The thing with these USB devices as well is that they basically use SCSI modules to work (hence the /dev/sda1, /dev/sdb1 lingo).

    sd_mod should be loaded (listed in lsmod), unless it is compiled into the kernel along with usbstorage. Also check the SCSI options in the kernel config.
