SD to USB adapter: No medium found

Werzi2001 · 2015-03-08 10:19:58

Hi,

i have a new micro-SD to USB adapter but i doesn't work properly.

Output of dmesg when i insert the USB adapter:

$ dmesg
[...]
scsi 7:0:0:0: Direct-Access     Generic  STORAGE DEVICE   0272 PQ: 0 ANSI: 0
sd 7:0:0:0: [sdb] Attached SCSI removable disk

In /dev there is just sdb and no partitions although the micro-SD card has already a partition (just one). If i use the micro-SD card in the SD card slot this works properly:

$ dmesg
[...]
mmc0: new SDHC card at address 1234
 mmcblk0: mmc0:1234 SA16G 14.6 GiB 
  mmcblk0: p1

So there must be a problem with the USB adapter.

Here just a few more information:

$ lsusb
[...]
Bus 002 Device 008: ID 05e3:0736 Genesys Logic, Inc. microSD Reader/Writer
[...]

$ fdisk /dev/sdb
fdisk: cannot open /dev/sdb: No medium found

But there is a medium and this medium already has a partition.

I already searched for the "No medium found" error but i could not find a solution. Does anybody has an idea of what is going wrong?

Best Regards

I had very similar or even the same problem some time ago.
Have you recompiled the kernel on your own?
If yes - maybe you forgot to select following option: CONFIG_SCSI_MULTI_LUN?
In my case without this option kernel allocated only one device in /dev/ (sdb, or so on), but with this option the kernel registers 4 block devices: sdb, sdc, sdd and sde. The connected micro-SD card will be accessible in one of those devices.

If this is a standard kernel from Arch distribution you may check it with:

zcat /proc/config.gz | grep CONFIG_SCSI_MULTI_LUN

Resurrecting this thread as I have a similar issue.

I have a 4GB SDHC card that is recognized, and mounts as expected when inserted into the SD card slot of my laptop but not when inserted into a USB multi-card reader. Further, regular SD cards are recognized, and mount as expected when inserted into the USB card reader. I'm trying to get this working for a laptop that doesn't have a built-in SD card slot hence the need for the USB card reader.

It seems the USB card reader (Transcend) doesn't recognize the SDHC card, only SD cards. Is there a driver update/change I can make to get this working or do I have to resort to a different card reader that supports SDHC?
