afaik, ferrite is to prevent noise/spike from and to the usb data line and rt2571 from the look of the picture. you can probably damage the usb side (pc) if...
1) you make unnecessary hack/mod like adding voltage to it (wireless adapter) circuit.
2) there is super strong megatonne watt EMI going on around, which is very unlikely i think.
as the posibility damaging the wireless adaptor due to noise from pc, well, u just bring it back from death, then what are u worrying about? the second death may means RIP baby. and i believe if you motherboard is "no shit" brand, then it is well designed to prevent such event (noise). maybe you can still keep looking for the part, or leave it as is, the same to the linked picture by me above, in the mean time, enjoy the device!

ps: be aware, ferrite or no ferrite, modding the device will render the warranty voided and possibly damaging your device (manufacturer advice)
