windows 7 and omnia trouble

[valetudo025]

I did a quick searched and really didn't find anything helpful for my problem.
I just upgraded all my computers to windows 7 and i love it! but i just recently noticed that when i plug my phone into my computer windows seven cant recognize it. windows attempts to load drivers when i plug it in but fails to find them and the install fails. When i start WMDC manually it doesn't see it.

i thought maybe because the OS is new that may be the problem, but we are talking about a windows phone to a Windows OS...kinda silly they cant talk to each other.

my phone is running a custom ROM, its windows 6.5 with HTC touchFLO cooked by Adrynalyne.

PS i'am also using a new OEM USB cable i got from ebay beacuse i lost my original...don't think that matters but you never know. thanks for anyone that can help!
