Where are sdb1 and sdb2

[amdonati]

Hello,
I have just bought the PQI TravelFlash 5in1 USB Card reader / writer and I wnated to install it in Gentoo.

It is recognised as a scsi device and is put under scsi2 (scsi0 are my cds and scsi1 is the iomega zip).
I suppose this means that I should use sdb1 and sdb2 (I have a CF and a SD card in it) as mounting devices, but I have none.
If I look in /dev/scsi/host2/bus0/target0/lun0/, I only have a "disc" and a "generic" device.

Do you know what devices should I mountor what are the mknod parameters for creating sdb1 and sdb2 (if, as I suppose, the cards should be mounted there).

I do not have usb serial support in the kernel because I do not think it is needed here, am I right?

Thank you for the help,

Adalberto
