USB connection of K30

I don't have a card reader or a card slot in my computer, so I attach my K30 to the computer with the supplied USB cord.

However, I have been having problems with this connection. This doesn't happen all the time, but occasionally as I am copying data over, the camera just disconnects itself from the computer and the computer says "eject disk before removing".

Then I have to turn the camera off, turn it back on again, wait as it copies more photos over before disconnecting again

Anyone else been having this problem, or anyone know a solution? Again, this doesn't happen all the time, only occasionally

Could be a loose USB connector or low battery voltage. This started happening with my phone's USB cable, so I replaced it and that solved the problem.

Probably cheaper and more convenient to by a card reader. You can get USB to SD readers for next to nothing.

If your computer has both frontal and rear USB ports, and you are using frontal ones, try to attach the camera to one of the rear ports.
It helps with some devices.

no problem here, but I am using a powered usb hub.

But the K-30 is really, really slow. I get a multitude higher transfer rate using a cheapo card reader. So if I am transfering more than just a handful of files, I take the card out.

Agree with Adam, it could be mechano-electrical. It might just be over cautious, but those tiny sockets and their connections inside seem a little fragile for really frequent use without risk of some sort of loose connection forming. I try to avoid using plugs and cables for routine connection to things that fit that much soldering and that many pins into one small area - if there's an alternative. It's friends' phones I hear most of the horror stories with.... A memory card reader seems a safer bet for long term reliable use.

1+ on the card reader option.

But it doesn't do this all the time. And it doesn't take long for it to stop. Also, the camera isn't turning off, but only disconnecting.

But i'll make sure to check what my settings are. Thanks!

make sure you are not using ptp. Make sure you connect the cable either to one of the onboard usb ports or a powered (!) hub. If you have an AMD based mobo, make sure C1E is turned off.

picture transfer protocol. It is in the camera settings. Can either be MSC or PTP. With MSC the camera acts like an usb stick.

Get a cheap USB 3.0 single slot SD card reader if you have USB 3.0. My 6 Betron from Amazon flies. I gave up on multi-card readers as most mess up Windows Explorer with a multitude of phantom drives.
