Nokia N900 conected to a PC via USB cable in mass storage mode exports two partitions - one from internal flash, the other from microsd card. WindowsXP sees them both as H: and I: removable discs. However, in gentoo I see only /dev/sdb, no /dev/sdc at all. Reproducible: Always Steps to Reproduce: 1. buy N900 2. connect it to a gentoo system via USB cable and select "mass storage mode" on the phone 3.ls -l /dev/sd[bc]* Actual Results: brw-rw---- 1 root disk 8, 16 Jan 25 21:37 /dev/sdb Expected Results: brw-rw---- 1 root disk 8, 16 Jan 25 21:37 /dev/sdb ..... /dev/sdc ....../dev/sdc1 dmesg log: hub 1-0:1.0: state 7 ports 8 chg 0000 evt 0002 ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001002 POWER sig=se0 CSC hub 1-0:1.0: port 1, status 0100, change 0001, 12 Mb/s usb 1-1: USB disconnect, address 5 usb 1-1: unregistering device usb 1-1: usb_disable_device nuking all URBs usb 1-1: unregistering interface 1-1:1.0 usb 1-1:1.0: uevent usb 1-1: uevent hub 1-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x100 hub 1-0:1.0: state 7 ports 8 chg 0000 evt 0002 ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001803 POWER sig=j CSC CONNECT hub 1-0:1.0: port 1, status 0501, change 0001, 480 Mb/s ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001002 POWER sig=se0 CSC hub 1-0:1.0: debounce: port 1: total 150ms stable 100ms status 0x100 hub 1-0:1.0: state 7 ports 8 chg 0000 evt 0002 hub 1-0:1.0: state 7 ports 8 chg 0000 evt 0002 ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001803 POWER sig=j CSC CONNECT hub 1-0:1.0: port 1, status 0501, change 0001, 480 Mb/s hub 1-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x501 ehci_hcd 0000:00:1d.7: port 1 high speed ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001005 POWER sig=se0 PE CONNECT usb 1-1: new high speed USB device using ehci_hcd and address 6 ehci_hcd 0000:00:1d.7: port 1 high speed ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001005 POWER sig=se0 PE CONNECT usb 1-1: default language 0x0409 usb 1-1: udev 6, busnum 1, minor = 5 usb 1-1: New USB device found, idVendor=0421, idProduct=01c7 usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1: Product: N900 (Storage Mode) usb 1-1: Manufacturer: Nokia usb 1-1: SerialNumber: 372041756775 usb 1-1: uevent usb 1-1: usb_probe_device usb 1-1: configuration #1 chosen from 2 choices usb 1-1: adding 1-1:1.0 (config #1, interface 0) usb 1-1:1.0: uevent usb-storage 1-1:1.0: usb_probe_interface usb-storage 1-1:1.0: usb_probe_interface -

Looks like some kernel options are missed. Also you get better chances to resolve this problem on support forums on in gentoo-user mailing list. Have you tried to ask there?
Post your .config, please. Do you have SCSI_MULTI_LUN enabled in your kernel? If not, can you enable and rebuild your kernel and test, please. Symbol: SCSI_MULTI_LUN Location: Device Drivers -> SCSI device support
Thanks, SCSI_MULTI_LUN was it. Sorry, I was not aware of this option, N900 was the first multi-LUN device I met. Perhaps this option should be Y by default, or would that cause some problems? I am sure I was not the only ignorant user...
No need to apologize, that's why we're here. We actually don't set anything in .config, we go with upstreams defaults as we try to keep things as close to them as possible.
