USB disconnect when downloading images from Canon PowerShot S50

I have been attempting to download photos from my Canon PowerShot S50. When I connect the camera it is correctly detected. However, when I attempt to download (a large number of) photos it fails after some time, and I see the following in the kernel ring buffer:

$ dmesg | tail
[17203180.356000] usb 2-1: USB disconnect, address 2
[17203648.852000] usb 2-1: new full speed USB device using uhci_hcd and address 3
