Hi all, I have a USB attached multi slot memory card reader which I use with FreeBSD-4.11. It has worked just fine with CFC cards for ages. A while ago I managed to get it work briefly with the MMC card used in Nokia 9300 mobile phones. Later when I have tried the same physical MMC card again it refuses to co-operate, but the CFCs seem to work just fine. This does not seem to be a problem in the MMC itself because it still works fine with the phone. The MMC just no longer works with FreeBSD and multi slot reader. Is this a known symptom of some sort of a quirk missing in scsi_da.c or something similar? When I apply "camcontrol rescan 4:0:2" this gets logged to the system console... da6 at umass-sim0 bus 0 target 0 lun 2 da6: <Zynet USB Storage-MMC I03A> Removable Direct Access SCSI-0 device da6: 650KB/s transfers da6: 122MB (250880 512 byte sectors: 64H 32S/T 122C) So, the MMC definitely is there, and it has been recognized. When I try to mount the thing... mount -p -t msdos /dev/da5s1 /USB/flash I get this... (da6:umass-sim0:0:0:2): READ(10). CDB: 28 40 0 0 0 0 0 0 1 0 (da6:umass-sim0:0:0:2): MEDIUM ERROR asc:11,0 (da6:umass-sim0:0:0:2): Unrecovered read error da6: reading primary partition table: error reading fsbn 0 msdos: /dev/da6s1: Input/output error WHat should I make of this? Do these symptoms ring a bell? Are there any hints what to try next? Cheers, // jau .--- ..- -.- -.- .- .- .-.-.- ..- -.- -.- --- -. . -. / Jukka A. Ukkonen, Mawit Ltd, Finland /__ M.Sc.
