I had plug an external USB hard drive which was detected here:

device: 
/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-7/1-7:1.0/host2/target2:0:0/2:0:0:0/block/sdb/sdb1
You probably know it better as /dev/sdb1 It's formatted as ext3!

and there:

Internal drives, anyone?  With serial numbers?
/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-7/1-7:1.0/host2/target2:0:0/2:0:0:0/block/sdb:
SAMSUNG_HM500JI_1F90179626FF-0:0 
/sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda:
ST910021AS_5MH0A42E

/dev/sdb is the external one, on USB, /dev/sda the internal one. The
output doesn't seem right and I understand your questioni now.

On the other hand, there was a CD in /dev/sr0, as shown here:

device: /sys/devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0
You probably know it better as /dev/sr0 It's formatted as iso9660!

I plugged an USB mouse at the end of the test, as asked.
