I have to ask - what drivers are being used in Device Manager for the various listed USB host controllers?
Look in Properties, in General, Driver, Details and Events Tabs?
I have no problems with using and ejecting USB drives, and have upgraded on this path:
10074->10240->10525->10532->10547->10565, no clean install.
I did make sure that all the Intel chipset drivers were upgraded from Microsoft generic to Intel in 10240, and that the Intel (R) drivers were in place in each subsequent update, and have migrated OK.
I have an AMD laptop (HP/Compaq Presario u/g to Windows 8.1) that point blank will not load the latest Catalyst AMD drivers, and if I individually force update ("have disk" and point to the driver location) the USB filter drivers to AMD, complains that it is "not recommended" because "Windows cannot verify compatibility with your hardware" - but the installation completes OK - Windows driver certificate and all. At some future time Windows will rollback to a generic MS USB driver. Frustrating.
