флешка SD memory Card, нашел в ядре опцию:
SanDisk SDDR-09 (and other SmartMedia) support, включил.
Теперь имеется:
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: eUSB Model: MultiMediaCard Rev:
Type: Direct-Access ANSI SCSI revision: 02
Как мне с этим работать?

Монтируй как скази-диск и работай.

в том то все и дело, scsi0 отсутствует, что еще можно подмонтировать я без понятия.

Usb имитируется SCSI - это стандартный прием

хех, я вижу что это эмуляция scsi :)
я спрашиваю - какой девайс может это все держать, как его имя в /dev/, или как мне узнать это все, где смотреть? :)

Смотреть - usbvew,  dmesg
устройства - /dev/sda1 .... /dev/sdMN

вобщем  перебрал /dev/sdaX,sdbX,sdcX,sddX,sdeX все: is not a valid block device.
usbview отсутствует, dmesg выдал:

вот такая вот петрушка.

все разобрался, забыл в ядре включить SCSI Disk support
