The problem with these dongles is that sometimes there’s a rev A and a 
rev B which use entirely different chipsets and hence are entirely 
different drivers.  That is rarely observable from online shopping sites 
or even product packaging.   I haven’t checked this particular case 
but if you can send me a usbconfig dump_device_desc for it I can go an 
have a look.
