In search of my problem with my new USB-3.0-Cardreader i found this mailiglist. I collected some more facts about the problem reading SDHC-Cards with an USB-3.0 cardreader: Cardreaders: - I have the same problem with the Transcend RDF8K - same problem on Kingston Media Reader FCR-HS3 - same problem on Hama All in One SuperSpeed-Multi-Cardreader Problem is also on different USB-3.0-Chipsets: - NEC Corporation uPD720200 USB 3.0 Host Controller (rev 03) - Renesas Technology Corp. Device 0015 (rev 02) - Etron Technology, Inc. EJ168 USB 3.0 Host Controller (rev 01) not working cards I have tested: - SanDisk Extreme III SDHC 8GB - SanDisk Extreme III SDHC 4GB - SanDisk SDHC 4GB The cardreader works: - attached to USB-2.0 - with SDXC-Cards MacOS seems to have the same Problem, on Windows 7 all works as it should without a special manufacturer driver for the cardreader. Tested on following kernels: - 3.1.10 (opensuse) - 3.5.1 (opensuse) - 3.6.0-rc1-20120814 (vanilla) Since now only a few people use USB-3.0 and the special cardreaders. I hope my facts will help and the problem will be solved soon.
