[] Possibly, but then why is it ok with USB 1.1 cards? What do you mean by this? You can read 512MB if you plus the reader into a USB 1.1 port? As Wolfgang said, the CF cards are neither USB 1.0, 1.1 or 2.0. David |

I just wonder if mine is forwards compatible with USB 2.0 I think that's called precognition in metaphysical parlance. g I see your point, the compatibility would have to be in the hands of the card manufacturer, allowing it to be read by older readers. dvus |

As Wolfgang said, the CF cards are neither USB 1.0, 1.1 or 2.0. Ok, then I guess the question becomes "Why will my older reader read 256 Mb cards but not 512 Mb cards?" I suppose it may have been built unable to address over 256 Mb, if I could find the "manual" that came with it I might be able to verify this. Or, it could be a faulty pin, as WW suggested, however it seems the chances of losing only the pin(s) that allow addressing higher capacity cards seems remote. -- dvus |

Some of the older readers didn't anticipate the need for greater than 256mb cards. Some cameras can't read SD cards that are 512+mb. As I posted elsewhere, an answer from SanDisk expresses an incompatibility situation. They said: "We have seen some problems with our Newer Cards not reading correctly in the SDDR-75. (Extreme) (Ultra2) (All new Cards) These newer cards are much faster then our older cards and the reader may be having problems reading these faster cards." Guess I'm screwed with the SDDR-75. dvus |
