Mogul no longer recognized by Activesync/PC

[phunzoid]

my Mogul and Activesync were working fine, on 2 different PCs, but now the mogul is not recognized at all by either PC...i get the same error message on both PCs about a USB device not working properly and that XP can't recognize the device

i completely uninstalled then reinstalled the latest Activesync on both computers, soft booted the mogul a couple of times, but still nothing....just that nasty error message

the only thing i've been playing around with is syncing my mogul with Mail2Web.com's exchange servers and Yahoo Go!...but this hasn't caused a problem with AS before

what could have caused this?

also, i read something about changing some settings at Settings-Connections-USB to PC, but when I try to go to that screen i immediately get dumped back to the mogul's desktop...which leads me to believe something got corrupted somewhere
