The man page for lsusb shows a file of USB devices

/usr/share/hwdata/usb.ids
              A list of all known USB ID's (vendors, products, classes,
              subclasses and protocols).

Perhaps, your device is not yet in that file, and so isn't recognized?

I've never done this, so can't help.  What about putting a blacklist
file in /etc/modprobe.d for the rtsx_usb driver?  If the kernel then
doesn't automatically fall back to usbhid, you can modprobe it after
start, and it should pick up your device.
