asked on USB ports don't respond to removed drive
I have a library on a cd emulation usb drive. The computer describes it as a cd drive. When it is inserted the first time, it works properly. If it is removed, the system no longer recognizes it and it doesn't appear. Sometimes one of the ports reports error 47
Code 47 error is one of the common device manager code errors generated for peripheral devices. The full error message is Windows cannot use this hardware device because it has been prepared for “safe removal”, but it has not been removed from the computer
The device does not come up as a device that needs to be disconnected. How can this be repaired?

Device manager says
Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)
The driver could not be loaded because a previous version of the driver is still in memory.
It seems that most of the solutions are to reboot

There seems to be only the ugly solution of reboot.
I'm also curious to know if this happens when you wake the pc from sleep or hibernate?
If so you can try this,
Open control panel. Now select power options. On the left select choose what the power buttons do.
Click change settings that are currently available.
Under shutdown settings, Uncheck turn on fast startup.
Try again with the usb device after a fresh reboot.
Try putting the pc to sleep and then wake it up to see if the device is now detected and also not in memory.

Either way, go to Control Panel - Administrative Tools - Computer Management, then go to Disk Management and see if it shows up in there. You might have it configured a different way or something.
If you go into Device Manager, have it "show disconnected devices" and see if it appears, then manually remove it and try reinserting.
