To my knowledge it is possible to "flip the removable media bit" on USB Sticks with the device manufacturer's tool, to make them appear as fixed media (or back to removable media) under Windows. Could you include this feature in your USB stick config tool?
"The removable media device setting is a flag contained within the SCSI Inquiry Data response to the SCSI Inquiry command. Bit 7 of byte 1 (indexed from 0) is the Removable Media Bit (RMB). An RMB set to zero indicates that the device is not a removable media device. An RMB of one indicates that the device is a removable media device. Drivers obtain this information by using the StorageDeviceProperty request."
