Description Andrew Charnley 2016-06-08 06:52:10 UTC 
This device supports 128Gb cards but the rtsx_usb driver corrupts the data. Devices are found but the mounting process will fail due to the corruption.

A quick search on Google indicates others have had this problem on Linux, but few are using 128Gb cards at the moment so it's not widely reported.

My card is: Kingston SDXC I SD10VG2/128GB

(this card is genuine, capacity tested and works fine in other readers. It also works fine on the RTS5129 within Windows).

This bug report will be emailed to Realtek.
