However, in doing that, I had the opportunity to do some thorough testing on my USB ports. I'm reasonably sure they're not the problem. They all respond the same way to the card reader and the camera, but they work fine with my flash drives. Funny thing, though, is that the ATA-to-USB converter I am using to transfer the disk images from my old 40GB Maxtor to a not-as-old 160GB Maxtor is flaky - I would copied all the files on the 40GB partitions (2) to one of my hard drives, changed disks and copied them back from my hard drive to the 160GB drive's larger partitions (something that MaxBlast used to do nicely but is now almost totally useless for, unless you want _it_ to control the partitioning), and I could never get a consistent file compare through the connector. I could run three compares in a row and get three different results. (Did this whole process twice, too.) BUT, when I copied the files from one of my hard drives to another, those all compared perfectly (of course), and when I tested the exact same USB port using a flash drive, I also had no problems with the compares. Also tested on another USB port (on the back, through an extension cable) - same result (good compare). Bottom line: I'm pretty sure my CentOS box USB ports are all just fine (they'd better be - I just got a new motherboard last fall), but I'm going to get a new card reader today for the camera/SD issue, and I'm thinking of returning the ATA-USB converter to the manufacturer as defective, just as soon as I get the XP box up and running and can verify _there_ (under a "supported" OS) that the same problem occurs. > Try a completely different PC, That's next if the new reader doesn't like my CentOS box, or vice-versa, unless I get the WinXP box up and running first.... > and if that doesn't work, you need to > call Canon. Canon doesn't support Linux (hahahahahahaha!), but they did recommend using a card reader, so, hopefully, the new one will be that answer. Just for the heck of it, I also tried playing the SD card in my wife's SX5 and that was a bust - for one thing, the SX5 is 8MP and the SX10 is 10.3, and it looks like they use different video formats, but the SX5 also said the SD card was in an unrecognized format (!) - not sure exactly what to make of that (other than that the SX5 will not help - duh!). Thanks, all. mhr
