USB Drives, Icons & Setup
I'm using Mandrake Linux 10.1 on a Compaq Deskpro PC which has two USB ports. I recently plugged in a 64MB 'flashdrive' into the USB port, and was delighted to find that Linux not only found the disk drive automatically, but also mounted the disk and showed it as an icon (both under Gnome and KDE) with the correct name. Files put on the USB drive by Windows 2000 could be read, and I was able to write new files to the drive. When I'd completed this I dismounted the drive using the "umount" command before removing the drive from the USB port, and the drive icon disappeared from the KDE (and Gnome) screen.
My problem arose when I later re-inserted the drive into the USB port. Whilst the drive lights flashed, the icons did not reappear and the device had to be mounted manually. Whilst this is OK, it lacks the convenience of what happened beforehand. How can the original situation be restored such that it happens each time the drive is inserted? How should I remove the memory stick from the USB port - simply pull it out, or is some form of "umount" or equivalent command required (as for Windows) beforehand?
I noticed that the device appears as a SCSI drive. As I already have a SCSI disk 'sda1' on the system, the USB pen drive was seen as 'sdb1'. I don't know if this has any bearing on the problems I'm experiencing.
I subsequently went on to connect a USB-based memory card reader to the same USB port. Under Windows this appears a 4 drives, and under Linux I expected a similar result. However, no drives were detected at all, even though one slot contained a compact-flash card! Are there problems with detecting such devices in Linux? My hope was to be able to archive the JPEG files on the card from my camera onto the hard disk before processing them using the GIMP.
I hope you can cast some light on these problems!
