Hacking Complie Hermes with Swapped USB ports

One of my USB ports on the Wii has stopped working properly, and naturally, it's the one I need for loaders to function. At least that's my assumption at this point - I haven't been able to get any USB loader to work for a few months, and it died overnight one night without me making any changes. I've found that if I revert back to Wakinono's cIOS Rev10, I can successfully access my wbfs partitions using the other USB port - but not using the one commonly used these days.

Looking at the source code for Hermes Rev 4 (Or oggzee's FAT version), it *looks* like I should be able to modify tiny_ehci_glue.c within the ehcmodule and just change ehci->num_port=1; to a "2"... but I've tried that, and (at least for me) it doesn't have any effect. Oggzee suggested I should be able to compile just the ehcmodule and store the resulting .elf in the usb-loader directory. When that didn't result in any change, I went as far as substituting both the ehcmodule4_elf and ehcmodule_fat from the build's data directory and modified the file sizes in sys.c - still with no apparent effect.

Did or could someone attempt to switch the USB ports in this manner? I'm thinking my programming changes may be much easier to test on a known good Wii - or by someone that really knows what they're doing with this code. My C skills are weak, and my Wii programming skills are far weaker. I would be very grateful if someone could either build me a working ehcmodule with the ports switched, or at the very least, attempt to change the 1 to a 2 for the num_port setting and let me know if that successfully enables the other port for you? I don't have another Wii to test with, and although I'm able to compile things, it just doesn't seem to be working out for me.
