It works much better with sanXi reader (<20120824111628.usmh54g2iv2yxcxo@xxxxxxxxxxxxxxx> for more info), though not very fast read/write speeds (can xhci debug slow it down?). But with RDF8 reader I just got write errors pretty quickly after starting writing to the Transcend SDHC. With Sandisk card it works OK just like with older kernels. (Also, my Nikon D60 has no trouble accessing any of the cards.) dmesg-xhci.txt https://docs.google.com/file/d/0B_EMXtsx7o56Z2dFYnpUM05iNFk/edit usbmon-rdf8-usb3.txt https://docs.google.com/file/d/0B_EMXtsx7o56OWNSTEVkX2xkRnc/edit usbmon-rdf8-usb2.txt https://docs.google.com/file/d/0B_EMXtsx7o56ZUd1Tk9DR2xlTGM/edit -- Do what you love because life is too short for anything else. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
