Kindle USB "device probem"
I posted about mounting a kindle last year but I'm starting a new thread because this is a different problem on a different desktop (Dell Optiplex 3020).
When I plug in the kindle,it seems to be recognized at first and it does charge. But I can't mount the device and there is a dmesg entry (repeated multiple times) saying there is a device problem. Here is the relevant part of dmesg and also the output of disklabel. dmesg: uhidev3 at uhub0 port 5 configuration 1 interface 0 "vendor 0x1949 USB Charger" rev 2.00/2.00 addr 5 uhidev3: iclass 3/0 uhid2 at uhidev3: input=1, output=0, feature=0 uhid2 detached uhidev3 detached umass0 at uhub0 port 5 configuration 1 interface 0 "vendor 0x1949 Internal Storage" rev 2.00/4.01 addr 5 umass0: using SCSI over Bulk-Only scsibus4 at umass0: 2 targets, initiator 0 scsibus4 detached umass0 detached uhub0: device problem, disabling port 5 disklabel: # /dev/rsd0c: type: SCSI disk: SCSI disk label: WDC WD5000AAKX-7 duid: b4afcc40682f0dc2 flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 60801 total sectors: 976773168 boundstart: 64 boundend: 976768065 drivedata: 0 16 partitions: # size offset fstype [fsize bsize cpg] a: 2097152 64 4.2BSD 2048 16384 12958 # / b: 8714560 2097216 swap # none c: 976773168 0 unused d: 8388608 10811776 4.2BSD 2048 16384 12958 # /tmp e: 24769152 19200384 4.2BSD 2048 16384 12958 # /var f: 4194304 43969536 4.2BSD 2048 16384 12958 # /usr g: 2097152 48163840 4.2BSD 2048 16384 12958 # /usr/X11R6 h: 104862624 50260992 4.2BSD 2048 16384 12958 # /usr/local i: 12594976 155123616 4.2BSD 2048 16384 12958 # /usr/obj j: 251674272 167718592 4.2BSD 2048 16384 12958 # /home |

After some more experiments, I find that I can mount a different Kindle (Paperwhite). The problem is specific to the Oasis. I'm continuing to experiment.

Thanks very much, Iggimi; illuminating, as usual. It was very useful to know that the module had not changed recently.
Encouraged by this, I had another go at the Oasis and found getting it to be recognised depended on the exact sequence of steps. I needed to connect the USB lead first and then to put the Kindle to sleep and wake it up again. A bit odd, but it works. |

I'm coming back to this because the solution I posted last time turned out not to be the full answer. I still found both my kindles not being recognised most of the time. But I think this time I have got a solution: after I do a hard reset on the computer (turn the power off complately for about 30 sec.) the device is recognsed correctly. I've now done this several times and it seems to be reliable.
