Kobo Touch corruption

[George Deluca]

Got new Kobo Touch. Works fine with Kobo Desktop, no problems. Add 1 book via CaLibre and Kobo on power up it starts reporting eReader memory corruption and recommends a Factory Reset. Cannot connect any longer to Kobo Desktop, it goes "Oops! your reader needs a Factory reset. After doing the reset and re-initialize at least three times and ending back at the same spot, I tried again and this time instead of adding the book with CaLibre, I just copied it with Windows Explorer and all has been fine.

Sure looks like CaLibre and the Kobo Touch do not get along well together.

CaLibre is at 0.8.10 I see 0.8.11 is out but nothing in the changes seems to address this issue).

Kobo is at 1.9.6 (r30320), Jul 13, 2011)

I am also having a problem with the attachment of Kobo Touch. I have to copy the books to the root directory of the Touch. After entering several books and disconnecting the device it does a "Processing Content" This never seems to encounter a loop.

[George Stout (georges611)]

The following info was shown for the device.

USB Vendor ID (in hex): 0x2237
USB Product ID (in hex): 0x4163
USB Revision ID (in hex): 0x0326
Windows main memory vendor string: KOBO
Windows main memory ID string: EREADER

I also have a Kobo Touch and have the same problem.

After copying a book to the touch, it shows up as 2 books on the touch. One book appears to be the cover and the other is the book with no cover. The book itself shows html code as the first page and the following pages are not properly formatted. HTML appears on several pages. I am using 0.8.12 on calibre and the latest fix level on the touch. Windows 7. The touch appears as a drive letter plus another drive letter for the SD slot.

Hi

Are you connected through an USB hub or extension cable? I am using Linux and the only time I encountered this issue was using an extension cable. It was reliably repeatable with the cable but has not reoccurred with the original cable only.

Hi Timothy,

I was connected directly, no hub. Corruption occurred using my desktop
system or my wife's laptop, so I don't yjhink using or not using a hub is
involved.

I was also connected directly through a USA port on my desktop system. I had to do a "Save to Disk" since there is no driver available yet.

[George Stout (georges611)]

In order to eliminate the USB connection I did the following test:

copied a book to the a Micro SD card in my card reader (Windows 7 Desktop)
put the SD card into the Kobo Touch
It then shows 2 books ( a cover picture and a book without a cover)
The book itself seems to be fine.

Even without transferring a book from/to the Kobo Touch, I've had this problem.

Started Calibre, plugged in the Kobo Touch then safely removed it. When unplugged, Kobo asked me to do a factory reset. Since I've stopped using Calibre to side-load books to my Kobo, I've not had this problem.

[George Deluca (gddeluca)]

Last night my Kobo installed a new update (1.9.9) so today I updated Calibre as well to 0.8.15 and thought I'd try these all out together. The Kobo update said it included 'stability fixes' (whatever that means) so I thought it was worth a test.

So far all now looks just fine. I've Sync'd Kobo with Kobo desktop. I've added a book to Kobo via Calibre and Kobo seems happy. Previously, this was where a power on ended up with memory corruption errors and Kobo Desktop issued "Oops, you Kobo need a factory reset" messages. I've Sync'd again with Kobo desktop. Powered on and off the Kobo, switched books etc. and all seems well.

Not exactly an exhaustive test, but previously all of this would have been impossible. So, since Kobo mentioned 'stability fixes' and Calibre doesn't seem to have changed at all in this area, it sure looks like Kobo was at fault in this problem. Only longer term usage and other users experience will let us know for sure.

Fingers are crossed this has been resolved. Looking forward to other users comments
