Ronald -- A quick review on the verbose log shows a few interesting things: 1) The device claims to use the USB Mass Storage Class, so it should work with usb-storage. 2) The device identifies itself to the SCSI layer as "rockchip rk28 sdk demo" -- a string like that is not very encouraging to me in terms of believing this is a released and fully-tested prodcut. 3) The device should appear as /dev/sdb according to the logs 4) Something in your system is polling the device, waiting for it to become "ready". HOWEVER, the device is continually answering with "Not Ready: Medium not present" Matt On Thu, Feb 14, 2013 at 10:47 PM, Ronald <ronald645@xxxxxxxxx> wrote: >> This e-mail is a follow-up as requested in this bug[1].
