The RTL8192DU is an older Wifi 4 dual band chip. It comes in two flavours: single MAC single PHY (like most Realtek Wifi 4 USB devices), and dual MAC dual PHY. The single MAC single PHY version is 2T2R and can work either in the 2.4 GHz band or the 5 GHz band. The dual MAC dual PHY version has two USB interfaces and appears to the system as two separate 1T1R Wifi devices, one working in the 2.4 GHz band, the other in the 5 GHz band. This was tested only with a single MAC single PHY device, mostly in station mode. The speeds in the 2.4 GHz band with 20 MHz channel width are similar to the out-of-tree driver: 85/51 megabits/second. Stefan Lippers-Hollmann tested the speed in the 5 GHz band with 40 MHz channel width: 173/99 megabits/second. It was also tested briefly in AP mode. It's emitting beacons and my phone can connect to it.
