Card reader invisible to USB port

[David H]

My Jessop's card reader works perfectly on my laptop, but after some months on the PC started turning on and off randomly, until the off virtually took over after having to plug it in and take it out endless times to get it to work. I checked the device manager and got this beauty:

"Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47)"

I followed the official Microsoft advice to no avail, and the only alternative was some shonky program that will probably want money after running before it'll do anything. There's nothing faulty as all the usb ports work for the other hardware as I've swapped a few to check, and I haven't done anything new since I installed it so what can I do as it won't connect at all now, the power is on but it won't actually become active when a card is plugged in.

To sum up, the card reader works on the laptop, but not the PC. But your can plug other things into the same PC USB port and they work ok.

My guess would be a driver issue. Try reinstalling whatever you used to get the thing running on the PC initially.

The recommended fix from MS is to restart the computer while the reader is plugged in.


If that doesn't work I'd start device manager showing non-present devices (see below) delete the entry for the card reader, do a restart and then plug the reader in again.
