usb/177895: similar 1TB Western Digital "My Passports" - some load, some don't

[Velcro Leaf]

Got a new one of these with the same model number as the previous versions, but still different behavior this time.

When you connect it, it says this:

usbd_setup_device_desc: getting device descriptor at addr 2 failed, USB_ERR_STALLED
ugen1.2: <Western Digital> at usbus1
umass0: <Western Digital My Passport 07A8, class 0/0, rev 2.10/10.33, addr 2> on usbus1

The USB_ERR_STALLED thing is new.

The drive seems to work on some machines, but on at least one machine, nothing at all happens when you plug it in.  (Well, no messages, anyway.)


I've updated to 9.1-RELEASE-p4 but I don't think that has included any of the potential USB fixes, such as the patch here: http://www.freebsd.org/cgi/query-pr.cgi?pr=178771

Any tests I can run to try to get this one figured out?

I can't work out a reasonable backup plan when every third drive (all of which have the same model number) doesn't function properly with FreeBSD.
