I am unable to use my SD card reader. Several weeks ago on inserting an SD card the system popped up the 'What would you like to do with this..' window and all went as expected. At the end of the session I umounted the card and removed it. The next time I inserted a card there was no response from the system, nothing was shown in either syslog or dmesg to indicate the card insertion had been noticed.
Running 'sginfo -l', as root, shows:-
/dev/scd0 /dev/sr0 /dev/sda /dev/sdb
/dev/sg0 [=/dev/sda scsi2 ch=0 id=0 lun=0]
/dev/sg1 [=/dev/sdb scsi4 ch=0 id=0 lun=0]
/dev/sg2 [=/dev/scd0 scsi5 ch=0 id=0 lun=0]
This is the same regardless of whether the card has been inserted or not.
The card reader is built into the PC & connect via USB. 'lsusb' shows it as:-
Bus 006 Device 002: ID 0aec:3050 Neodio Technologies Corp. ND3050 8-in-1 Card Reader
When inserting the card the led on the readers front panel flashes. That appears to be the only response from the computer.
I do not know whether the system is using HAL or vl-Hot. How do I find out & what is involved in changing over to the alternative should this be the problem? Whichever, this has not been changed, unless the system changes itself, since before card insertion worked several weeks ago.
'cat /etc/vector-version' gives 6.0 KDE-Classic built on November 8, 2009. Kernel is '220.127.116.11kdg' (the only changes from stock were CPU optimising for my Phenom x4).
No other system has problems reading or writing to this card. It is a new 'brand X' 2Gb card & was last written to by an XP box and was subsequently read from by my Garmin GPSmap 450 with no problem.
