Well, the drive doesn't actually work on the other computer, so something 
important is wrong.  The fact that the other machine silently fails is maybe 
more telling?

After many years in the USB game I feel a need to emphasize again, that many of 
the mass storage related errors reported here are not a USB HOST problem. There 
is a USB standard defined at www.usb.org, that we are trying to comply to.

I totally respect that, but all these devices work with other OSs (which shall 
remain unnamed).  There's intellectual purity and then there's getting the 
freaking things to work.  How do these other OSs deal with the quirks?  Is it a 
matter of downloading piles of drivers?

I do like the idea of a FreeBSD Seal of Approval.  It would save us all a lot 
of time.


Probably some that can be discussed at the next EuroBSDcon !

Any suggestion for fixing the problem?  (Other than the long term, but probably 
fruitless, suggestion of complaining to Western Digital?)

Could you try to look through the quirks list, using usbconfig and see if your device is really quirked like it should. I know there has been introduced an attempt to auto-detect quirks, and this is disabled if any quirks are set manually.
