When I connect the N900 to my desktop PC (Gentoo GNU/Linux), Gnome automounts it and I can access my home directory. (Looks ugly, but works.)

I can not, however, access (or even see) the microSD card. Both SD card and home directory disappear from the file manager the mopment I connect the USB cable, so I guess that on the N900 side things are OK... kind of.

dmesg gives me
usb 2-6: new high speed USB device using ehci_hcd and address 3
usb 2-6: configuration #1 chosen from 2 choices
scsi9 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 3
usb-storage: waiting for device to settle before scanning
scsi 9:0:0:0: Direct-Access Nokia N900 031 PQ: 0 ANSI: 2
sd 9:0:0:0: Attached scsi generic sg7 type 0
usb-storage: device scan complete
sd 9:0:0:0: [sdg] Attached SCSI removable disk
sd 9:0:0:0: [sdg] 56631296 512-byte logical blocks: (28.9 GB/27.0 GiB)
sd 9:0:0:0: [sdg] Assuming drive cache: write through
sd 9:0:0:0: [sdg] Assuming drive cache: write through
and mount tells me it's a VFAT volume:
/dev/sdg on /media/Nokia N900 type vfat (rw,nosuid,nodev,noatime,uhelper=hal,shortname=low er,flush,uid=1000)
Especially the output of dmesg doesn't look like there's anything besides /dev/sdg that could be mounted.

How does it look on other GNU/Linux computers? Is there something wrong with Maemo, with my N900 or with my desktop computer?
How does it work in Windows?

Sorry, I can't speak for the N900 but I used to have a multi card reader that showed up as two drives and only one appeared under linux. The problem was a kernel option called something like "SCSI: Probe multiple LUNs" needed to be enabled.
Failing that, why not try "mount -o bind /sdcardmountpoint /home/MyDocs/sdcard" on the n900 so you can just access the sd card from within the home directory.

EDIT: I've just noticed you run gentoo. That's what I used to run, and probe multiple luns isn't in the default kernel config, or at least it wasn't two years ago...

In Ubuntu when I plug it in it shows the N900 and the microSDHC card as two seperate mounts.

In Windows it operates the same way.

Thanks, I could verify on a friend's PC (Vista) meanwhile that my N900 does operate correctly, it does expose both the SD card and the home directory and Vista shows it as two separate drives.

The "Probe multiple LUNs" kernel config is something I'll have a look at, thank you very much, patstew!
I'm not at home right now but I'm sure I wouldn't have discovered that as a possible cause for my problem. I'll let you know if it was.

Mhm... probably this *would* have been the solution, but: As soon as I set this option in the kernel, the system refuses to boot. It re-boots almost immediately after I select the respective kernel version from the GRUB menu. - Well, guess I'll have to look into this later. Just good to know there's nothing wrong with my N900 and that, in fact, this LUN-setting is probably it.
