Subject: USB key generates ioctl_internal_command errors


Whenever I insert my Iomega Mini 1Gb USB key, I get a stream of
ioctl_internal_command errors. The device works just fine (mounting,
copying files, unmounting, etc), but the messages are annoying...

And this goes on and on...approx one message per second if hal is
running, otherwise only the first two ioctl_internal_command messages
are shown. I assume that hal is doing some kind of polling on the device
which triggers the error message. What does the error mean and how do I
fix it? I've seen some other posts on the list with similar error
messages but found no answers...

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

/*
* Pete Zaitcev <[email protected]>, 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",
US_SC_DEVICE, US_PR_DEVICE, NULL, US_FL_NOT_LOCKABLE ),

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 :-)
