Question MP3 player sd card mounting?


I have a RCA Lyra 1071 mp3 player with 128 MB flash memory and a 256 MB SD CARD for extra memory.
The unit itself(that is it's internal flash memory) mounts fine as such:

/dev/sda1 /mnt/lyra vfat defaults,noauto

My question is: How do I mount the expansion SD card ?
Under Windows XP it shows up as a separate hard drive. Unfortunately right now I have to use Windows to access it.(Pretty much the only thing I use Windows for) I hope it is possible to mount this card under Linux.

I am running Slackware 9.1 with kernel v. 2.6.2

well i'd guess it will be registered as either sda2 or sdb1, when you plug it in, check what "dmesg" tells you about the assignments.

I have tried sda2-15 and sdb1-2 and I always get a not a valid block device message.

When I dmesg the output is:

I just solved my own problem. I needed to reconfigure my kernel to enable it to search through multiple luns under scsi options. The sd card now mounts correctly under dev/sdb1 !

Thanks for the help

I am actually pretty frustrated. I even post a "how to mount your lyra" message some days ago. Now, I am having problems with the unit (I recompiled my kernel)

This is what dmesg reports when I connect the unit:

hub.c: new USB device 00:07.2-2, assigned address 10
usb.c: kmalloc IF c9edb780, numif 1
usb.c: new device strings: Mfr=1, Product=2, SerialNumber=3
usb.c: USB device number 10 default language ID 0x409
Manufacturer: Thomson
Product: RD1021 71 75
SerialNumber: 0000A1030193440A
usb-storage: act_altsettting is 0
usb-storage: id_index calculated to be: 75
usb-storage: Array length appears to be: 77
usb-storage: USB Mass Storage device detected
usb-storage: Endpoints: In: 0xd0644bc0 Out: 0xd0644bd4 Int: 0x00000000 (Period 0)
usb-storage: Found existing GUID 069b070f0000a1030193440a
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 10
usb.c: usb-storage driver claimed interface c9edb780

Apart from that, if I select the KDE Information module (USB Devices) I see the following:

RD1021 71 75

Manufacturer: Thomson
Serial #: 0000A1030193440A

All these modules are loaded:
usb-storage 69424 0 (unused)
scsi_mod 106200 2 [usb-storage sr_mod]

hid 21700 0 (unused)
input 5824 0 [keybdev hid mousedev]
usbcore 83264 1 [usb-storage hid uhci]

Only one of these are loaded at a time
------------------
usb-uhci 25868 0 (unused)
uhci 29712 0 (unused)


Do you think that I should?
a) Try with the usb-uhci modules instead of the uhci one?
b) Try to recompile the kernel and edit the usb-storage options

I hope somebody can help me here, since I was "helping" others before ;(

Regards

When I try to load the EHCI-HCD module I get this:

[root@localhost xavier]# modprobe -v ehci-hcd
/sbin/insmod /lib/modules/2.4.20-8custom/kernel/drivers/usb/hcd/ehci-hcd.o
Using /lib/modules/2.4.20-8custom/kernel/drivers/usb/hcd/ehci-hcd.o
Symbol version prefix ''
/lib/modules/2.4.20-8custom/kernel/drivers/usb/hcd/ehci-hcd.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20-8custom/kernel/drivers/usb/hcd/ehci-hcd.o: insmod /lib/modules/2.4.20-8custom/kernel/drivers/usb/hcd/ehci-hcd.o failed
/lib/modules/2.4.20-8custom/kernel/drivers/usb/hcd/ehci-hcd.o: insmod ehci-hcd failed

Any ideas?

When I unplug and plug my device I see the following:

May 27 20:17:18 localhost kernel: hub.c: new USB device 00:07.2-2, assigned address 4
May 27 20:17:18 localhost kernel: Manufacturer: Thomson

May 27 20:17:18 localhost kernel: SerialNumber: 0000A1030193440A


Could anybody tell me what does it means?

Ok I loaded the Scsi Generic Drive:
modprobe -v sg

Now, I receive this error (I started receiving it after I recompiled my kernel)

modprobe: Can't locate module block-major-8

Could anybody tell me where can I enable that block-major-8?

Is there any easier way to know which devices are connected to your Linux box?
I know I am offending many people, but Windows (haven't used it in months) has a nice Device Manager information

Is there any place where I can check which devices are connected to my pc?
(I would really like a graphical interface)

Regards

Hello,

I'm a newbie for that sort of things using Fedora Core 2. I can mount the internal memory of my PDP2444 (Thomson name for RCA PD1021) but not the external memory card.

Can you explain me with more details what you've done ?

Thanks.

SD Memory Card on Lyra Player

I've experimented with my wife's Lyra 1028 player on my MEPIS Linux Box with a KDE Desktop. The SD card won't show up so I found a "Work Around ".



* I put the SD card in the Card Reader intended for my digital camera
* It shows up in the KDE file browser (Mounts O.K.)
* I copy MP3 files using drag and drop techniques
* I put the card in the Lyra player - the songs show up on the menu.
