USB does not recognise camera

[mytinfox]

When I connect camera via the micro usb, nothing happens.

The tablet is supposed to be able to read the camera SD card directly via the USB.

I've tried two different cameras, both work fine via PC usb connection.

Seems to be real problems with the USB connectivity. I've reported similar issue with trying to access SD card via a reader.

Anyone else having similar problems?

Do you connect the camera directly to the Xperia tablet? As far as I understand you have to connect through a USB host adapter.

Do you know if the camera connects using MSC or MTP?

I connect via micro usb to female usb adapter. Same one I use for reading memory sticks and card reader.

I'm not sure whether MSC or MTP, I'm assuming MSC as on my laptop I read the sd card in the camera as a storage device.

Why is this topic assumed answered? There is no answer here.

If you assume stuff it won't help

You have to find out for sure which MSC/MTP is. The change the Settings in the tablet to match that.

However since you were also not able to read a card via the card reader you have to find out if your OTG adapter really works. Can you try another one ?

Make sure you can read a card via the reader first and then move onto the reading the camera problem.

Thanks for your suggestions.

I have tried connecting the camera with the Tablet set to MSC and then MTP - makes no difference.

I am able to read the SD card via a card reader connected via the OTG adapter. In fact I bought a second, high quality OTG adapter to eliminate this as the problem.

I also plugged the camera into the laptop to ensure the camera cable I'm using is ok too.

When I plug the camera into the laptop, the camera immediately recognises it is connected via USB (changes to copy mode) but when plugging into tablet nothing happens, ie it doesn't recognise a USB connection. The tablet also doesn't show it has anything connected via USB.

The only thing I would try more would be to connect the camera to the tablet via a powered USB hub (and that via the OTG adapter of course). It may be that the camera needs more than the 0.5A that the tablet is giving.

[mytinfox]

The camera works fine using computer USB 2.0 connection which is only 0.5A.

My suspicion, and that of others posted in this forum, is that the tablet is not giving the full 0.5A via the USB, so some devices are not getting enough juice.

No idea how to prove it though,

Actually most of the time it's the other way around: the PC-s don't obey the standard and give more current than as per the spec...
