Realtek card reader reports as an external USB storage when empty
 
Hi everyone and thanks for helping

I have a Toshiba Satellite L305-S5939 laptop and recently I noticed that when I was in Windows 7 and card reader was empty, it was still showing as a removable disk in 'My Computer'. At first I thought it was a driver problem. Then I formatted the hard disk and wanted to install OpenBSD on it (for learning purposes) and I got the AHCI PHY offline error. The result was that it couldn't access the CD-ROM and thus couldn't install the OS.

After that I went for installing Arch and in the TTY, this error showed up every minute:

Code:

sd 6:0:0:0: [sdb] Assuming drive cache: write through
sd 6:0:0:0: [sdb] Asking for cache data failed

So I ran 'dmesg | grep ahci -A 500' and got this (sda is the main hdd and sdc is Arch live usb):

Code:

What might be the problem?

rtmistler 03-05-2014 07:28 AM

It does not appear that you included your entire system log file, the detection part where this device is seen is not shown, I do not see any events for USB detection of this device in that system log.

Can you get a run of dmesg as it stands with the device in.

Unplug the device, wait a few seconds, then plug it back in, and then copy over the newer logs which appear in your system log showing the removal and re-detection? And then include the output of lsusb if it's any different from what you have now?

My question to you is whether or not there is any problem with cards in this drive? I always see that event "Assuming drive cache: write through" although I mainly see it once. I also know that for multi card readers it creates a device; such as /dev/sdb, or /dev/sdc, and so forth and when you plug in a SD card, Compact Flash card or whatever the multicard reader can read, it then makes driver enumerations matching the original letter. For instance if the reader is /dev/sdb, and you plug in an SD card with two partitions, it will then create /dev/sdb1, and /dev/sdb2 and most systems will try to mount them.

So the real question is why you think this is a problem at all? Are you not able to read cards when plugged into this reader?

Here's the full system log (The log was to long to mention here):

http://pastebin.com/bhfK8DmH

As I said, it is a laptop and the card reader is built-in; it's not an external device and even though nothing is in it, it still reports as a block device and system tries to access it. I have another laptop with a card reader and it does not report as one until I plug an SD card in. The error shown at the end of the dmesg spawns every minute on the TTY and in the middle of the prompt, and I have to clear the whole screen to be rid of it.

rtmistler 03-07-2014 07:04 AM

Sorry I misread and thought it was USB attached. I get that it's internal.

Your concern is that on the default console in ARCH Linux you get this notification message about once a minute?
Code:

sd 6:0:0:0: [sdb] Assuming drive cache: write through
sd 6:0:0:0: [sdb] Asking for cache data failed

That may be debug from the driver which is a complaint that there's no media there to read. Do cards work when plugged into that reader?

WinonuX 03-08-2014 09:15 AM

I don't have any card to try it with, unfortunately.
Is such a thing even normal? Have you experienced a similar problem?

Soadyheid 03-09-2014 05:47 PM

Realtek card reader reports as an external USB storage when empty
 
My multi card reader shows up when empty as well but I don't see it as a problem. I can access a card if it's loaded. The A: drive shows up on a windows machine as well but you can't access it if nothing's loaded. I don't think it's a problem.
Play Bonny!
