i'm out of ideas.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
thats my USB-to-serial adapter in Device Manager... code 43 appeared after moving the PC... i tried rolling back the driver, but the button is greyed out :) the same device works perfeclty on my laptop, so the hardware should be fine... if its a driver problem, Id like to fix it properly... if its hardware, Id like to know sooo i can stop wasting time, either answer would be a rleief at this point. im about to throw this thing out the window lol
