Description David Hamilton 2006-02-20 08:07:18 UTC

I'm having trouble mounting my RCA Lyra 1080 MP3 player (either its internal memory or SD card). I've compiled and am currently using kernel 2.6.15.4, but this identical problem occurs with the default kernel.

When I plug the device in dmesg reveals the following:

Mounting as /dev/sdb1, dmesg gives:

Mounting as /dev/sdb, dmesg gives:
end_request: I/O error, dev sdb, sector 0
FAT: unable to read boot sector

The command: fdisk /dev/sdb gives:
Unable to read /dev/sdb

I can successfully mount the Lyra's 1gb SD card in a separate USB 2 card reader using the same USB port. I can also use the player without problems in Windows XP and seem to recall getting it working in a version of Suse 9. I've got the latest firmware for the player installed.

Please also post the logs of the successful atempt with the other card reader.
And please attach cat /proc/bus/usb/devices for both cases.

Comment 5 Greg Kroah-Hartman 2006-02-21 22:56:51 UTC

Is there any way you can run a 2.6.15.4 kernel with CONFIG_USB_STORAGE_DEBUG enabled?  And if so, can you attach the kernel log output?  That will help
us try to figure out how to fix this device.

Judging from your usb-storage debugging log, the player reports that the card has one more sector of storage than it really does.  This patch should fix the problem.

Comment 11 David Hamilton 2006-02-22 22:54:35 UTC

Awesome!  The patch worked -- the device mounts successfully and there are no problems reading or writing to it.

Many thanks to all involved!

I'm not sure what the process is to get this into future linux kernels (or if it's indeed appropriate to burden linux users with a few extra bytes in the kernel sources to allow for this device's weird behaviour).  In any case I'll hold tight to that patch.  Thanks again!

Comment 12 Greg Kroah-Hartman 2006-02-23 23:14:37 UTC

Alan has forwarded me the patch.  It was just added to our internal kernel
source tree and will show up in the next kernel update.

It's also been added to my development tree and will make it into the main
kernel source tree soon.

Thanks for helping out in fixing this problem.
