Maybe I should set it to 1 as I have never seen an RT5592 recover from this. The system remained relatively stable until after I tried forcibly removing and then loading the rt2800usb module. A simple `ifconfig` then triggered a kernel panic. Sadly I couldn't capture it in time but I did spot that more phyN (up to phy4) devices had been added. Kind regards, jer
