Pentax Optio 50L


13 years 6 months ago #2087 by sleepydwarf
I have a little Pentax Optio 50L which has been working perfectly up until the weekend. Now every time I want to transfer pictures to the computer it comes up with: “Power Surge on Hub Port: - A USB device has exceeded the power limits of its hub port; Click this message; A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device. To re-enable the port, disconnect the hardware and click reset”. Okay, so I did this and still nothing. Does anyone know what this actually means and why all of a sudden it won't let me access my pictures? More importantly, does anyone know how to fix it?

Is it a powered hub? i.e. it has a mains transformer plugged into it? If it is, and the transformer is no longer powering the hub then the hub might be working as an 'unpowered hub' and doesn't like the extra load of your camera i.e. exceeding the current supply limits of unpowered hubs. Check fuses, connections etc of the transformer.

I forgot to mention, that I have an older digital camera - fujifilm FinePix - and I am able to plug that in to the same USB connection and download photos, but it just now decided it doesn’t like the Pentax - for no apparent reason. I have had the Pentax for 5 months and have had no problems - the camera works fine. I have checked all connections etc, but given that one camera works and now the Pentax doesn't, I initially thought it was the actual USB connection cable - which it isn't.

It simply means that the camera is drawing too much power. If it is plugged in Via a USB hub, plug it directly into the computer. The other camera working has nothing to do with it - perhaps the Pentax runs off the PC's power when the other one didn't. Or perhaps they just have different power requirements. As to why it's just happened now - have you added a new USB peripheral or anything? Or it might just be a Windows update or something that allows the computer to recognize that the camera's drawing a bit too much power. But using a USB hub (if you are) is generally a bad idea. Plug the cable directly into the PC or if it directly in the PC at the moment, try a different socket (I.e. if it's plugged in the back, try plugging it in the front and vice versa). But the best thing to do would be to buy a card reader.

At one of the schools I work at they had a Canon Ixus which would happily transfer pix from camera to computer using a usb cable then one day it suddenly would not transfer photos despite of trying another usb cable which worked on other cameras, weird. My solution was tell them to buy a card reader.

I second that suggestion - buy a card reader and put the SD card in the reader, so there's no need to connect the camera to the pc.

The camera could have developed a fault, which is causing it to draw more power than it should. As suggested get a card reader, downloading from the camera is a crap way of doing it.
