I think it's harmless. I saw things like that, and initially I plugged
them with workarounds like this:

* Pete Zaitcev <zaitcev@xxxxxxxxx>, from Patrick C. F. Ernzer, bz#162559.
* The key does not actually break, but it returns zero sense which
* makes our SCSI stack to print confusing messages.
UNUSUAL_DEV( 0x0457, 0x0150, 0x0100, 0x0100,
"USBest Technology", /* sold by Transcend */
"USB Mass Storage Device",

But perhaps we want the SCSI stack to do something about it, dunno.

If you're nervous about messages, use ub, it's mostly silent :-)
