im using this wirless keyboard and mouse combo, seem it works fine but here is weird thing, not on all USB ports on my PC. Lets say if i connect wirless adapter to port X it works fine, then i connect to port Y it starts to lag, i connect USB hub, i connect wirless adapter to USB hub's port A that is connected to port Y (on wich it was lagging), it works fine, i connect to port B of USB hub, works fine, i connect to port C of USB hub, i get BSOD.
I connect same combo mouse/keyboard to my laptop port, works fine, i connect to other laptop usb port, it lags. I connect via USB hub on same port i got BSOD on previous PC, it works just flawesly.
What reasons can be of such weird behaviour?

There are no devices on the hub i just switch ports of mouse reciever and on some lags on some not
