218e99
Add serial number compat properties to the rhel6 machine types,
218e99
to match rhel6 behavior.  Two things we have to watch out here:
218e99
218e99
First the HID devices flipped serial from "1" to "42" to indicate
218e99
remote wakeup capability, in RHEL-6.2.
218e99
218e99
rhel6 commit 85ae0a096fdbc4a6f5a660bf60a74c092f9c0f7a
218e99
218e99
Second devices get unique serial numbers, by appending host adapter
218e99
pci address and port path, in RHEL-6.4, for usb-hub and usb-storage.
218e99
Also usb-net + usb-serial + usb-wacom, but those are disabled in RHEL.
218e99
218e99
rhel6 commit e91156bc452250291f72b82b43654540be7101be
218e99
218e99
usb-ccid has a unique serial in RHEL-7 but not in RHEL-6, so we need
218e99
a compat property for all RHEL-6.x machine types.
