USB Question

EricArcadia · 08-12-2014, 03:39 PM

Am I the only one that faces very slow USB connection when connecting the Onyx Lynx T68 to the PC, as the PC reads the device when it's connected, but Calibre will take 3 mins to 20 mins to just register all the books and contents of the SD card? I've wasted so much time trying to work around this when it happens.

calibre always must scan all the books on the device before registering it. Usually, it will cache the results of the scan in a file called metadata.calibre, on the device. That way calibre only has to look for new stuff.

T68 -- that's the e-ink tablet. Since it is a tablet, it probably has stuff all over the place in the file system. calibre has to scan all of that even if most of it isn't books. You can set calibre so only certain folders are scanned for books, from the device driver. Exclude the places where books never go.

"Configure this device" in the dropdown under "Device" (in the toolbar).

Alright, thanks, I'll try that.

FWIW, I have almost 4000 books on my T68, and run Calibre Conpanion on it. The initial connection dialogue with Calibre (via the wireless connection of course) takes no more than 30s. If you've not looked at CC, I'd advise doing so.

I have CC

Why are you using a USB connection then? Sorry, I'm a little confused

EricArcadia · 08-15-2014, 03:04 PM

It's for transferring my books, and other data such audio books or mangas to the SD card. Sometimes the PC won't recognize the SD card that's in my T68, and I have to keep retrying for minutes, and then after that at times the Calibre program is very slow to read all the data on the SD card.

You should be using CCs wireless connection to transfer books.

Sorry, I perhaps didn't make myself clear before. What I was asking you is why you are using a USB connection with Calibre if you have Calibre Conpanion. CC's wireless connection is so much faster: as I said earlier in the thread, for me it does its initial sync with Calibre in under 30s, whereas you're find that a USB sync can take up to 30m. My question is why you're doing a USB sync at all.

EricArcadia · 08-16-2014, 01:36 AM

I don't use the wireless sync since I think it won't transfer the books to the SD card, but instead the on board memory of the device.

Well that transfer the books to the SD card, or the onboard memory of the device?

No, it will transfer books to wherever you tell CC to store its books. In CC, go to the "Settings" menu and use the "Formats and Folders" option to tell CC which formats to accept and where to store them. I have mine configured to only accept ePub and to store them in a folder called "Books" on the external SD card.

Alright, thanks I've tried that suggestion you gave, and it worked quite well, and it seems that I just need to be more patient as when I connected to the PC it took some time for the PC to register that there is a SD card attached to the T68. Thanks for your help.

Thanks, by the way, did you ever get a replacement for your T68?
