Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  usb microSD card reader report incorrect size (32gb instead of 64GB)
  of microSD card.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Using a 64GB microSDXC card in a usb sd card reader gives wrong SD
  card size (32GB). When putting the same microSDXC card in a a SD
  adapter it correctly gives 64GB size.

  Hardware:

  sdCard: SanDisk Extreme microSDXC UHS-I (http://www.sandisk.com/products/memory-cards/microsd/extreme-uhs-i-action-cameras/?capacity=64GB)
  USB card reader: Kingston FCR-MRG2 (http://www.kingston.com/us/support/technical/products?model=fcr-mrg2)
  SD adapter: Kingston (http://www.kingston.com/en/flash/microsd_cards#MBLY)

  Here is the output from terminal:
  Accessing it through USB card reader:
  $ sudo fdisk -l /dev/sdb 

  Disk /dev/sdb: 27.5 GiB, 29504831488 bytes, 57626624 sectors
  Units: sectors of 1 * 512 = 512 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disklabel type: dos
  Disk identifier: 0x00000000

  
  Accessing it through sd card adapter and the built-int sd card reader:
  $ sudo fdisk -l /dev/mmcblk0

  Disk /dev/mmcblk0: 59.5 GiB, 63864569856 bytes, 124735488 sectors
  Units: sectors of 1 * 512 = 512 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disklabel type: dos
  Disk identifier: 0x00000000


  
  My conclussion is that the driver for the usb card-reader.

  I will attach the output of lsusb -v -d 090c:6200
