Re: SD card suddenly not recognised by laptop

I've found USB to be a bit finnicky at times.   I've had occasions where I remove one card and slam another one in too fast and the USB driver doesn't seem to get a chance to reset - it ignores the new card and all the other cards inserted from that point on.   But the cards work fine if inserted into a reader attached to a different port.

My reader is connected to an external USB cable, so I'm able to to unplug it, wait for a few seconds, and then plug it back in again to reset it.   But if it was connected internally then I'd have to reboot my system.
