"It works, but we're sending you a new one." is about what the message on the answering machine amounted to. I sent in the USB hub & card reader that wouldn't read the camera's CompactFlash card as it was still within the warranty period. The message was from someone who claimed to have tested the thing with a few CF cards and had it read all of them. He said that a new unit would be shipped, but went on to suggest that large size cards don't show up right away (256 MB is hardly large these days and the 512 MB flash drives show up without any significant delay) and that the format makes a difference. I'm not sure what filesystem Canon uses, but that I could see it at all indicates that that should not be the issue.

Having done some troubleshooting and dealing with similar though not identical issues, I don't doubt that every test he did showed a(n apparently) properly working device. But that doesn't change that the device didn't work me or for jmaynard. I am a bit suspicious of the offered explanations. Hopefully the replacement hub & card reader will work for me and not just the test bench.
