Comment (by markh):

 I attached a small part of the syslog that shows what happens when the WD
 Elements drive is attached with TRACE_USB_DISK enabled.
 I did some further digging and I think I know where the problem is. The
 sense data contains additional data and this data clarifies exactly why
 the device is not responding (see
 https://en.wikipedia.org/wiki/Key_Code_Qualifier for the list). The WD
 Elements drive returns 04 01 as the response as can be seen in the log. I
 suspect the card reader returns something like 3A 00.
 If so, then we need to add code to interpret this additional data.
