Here it is:
root@test:/sys/class cat scsi_host/*/can_queue
1
root@test:/sys/class cat scsi_device/*/device/blacklist
root@test:/sys/class cat scsi_device/*/device/inquiry
Intenso Speed Line 1.00
root@test:/sys/class cat scsi_device/*/device/model
Speed Line
root@test:/sys/class cat scsi_device/*/device/queue*
1
none
root@test:/sys/class cat scsi_device/*/device/vendor
Intenso
I do not know, if there is something special about it. If needed, i can
take it apart to see what controller is used.
