I don't know.
If your magician has USB client directly from PXA SoC (not external PHY), then only host port 2 can be muxed with client.
Intel® PXA27x Processor Family, Developer’s Manual

I think there was no implementation in the Windows Mobile, but I was able to switch this mux and use a wifi usb dongle on the same connector as USB client.
