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
"12.5 USB On-The-Go Operation"
"Figure 12-15. USB OTG Configurations"
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.
