Hi linux-scsi people, the problem described (and worked around) during the conversation below seems to be related to your realm. I apologize if this is redundant and for not taking my own time to suggest a patch for it. However, as it affects users, I still wanted to get it out of my backlog and at least mention it here. Cheers Daniel -------- Original Message -------- Subject: Re: New USB storage device, not detected by Ubuntu 12.10 (kernel 3.5.0-17-generic) Date: Sun, 27 Jan 2013 13:22:42 -0800 From: Matthew Dharm <mdharm-usb@xxxxxxxxxxxxxxxxxx> To: Daniel <daniel@xxxxxxxxxxxxxx> I don't know. You would need to ask the linux-scsi mailing lists.
