6 looking at the ebuild for 'pci-utils' we see::
7
8 RDEPEND="${DEPEND}
9 sys-apps/hwids
10
11 So if you want the latest data on hwids, install::
12 'sys-apps/hwids-99999999'

21 OK, so both of you guys should use serial sniffers and usb sniffers and log
22 those sessions on a separate machine for rigorous analysis. Commercial
23 sniffers are very user friendly. Some cheap embedded boards can sniff usb
24 readily (but you'll have to search them out yourself).
25
26 For a usb sniffer, you may need special hardware to intercept those singnals
27 from the actual communications link. sniffing from inside
28 of a host is sometime problematic on catching every charcter, timings,
29 and other such critical signal information. sniffing RS-232 is well
30 documented around the net. When I sniff usb, I try to first use usb-1.0
31 or 1.1, as the slower speeds are easier to watch and collect critical data.
32
33 good-hunting.
