weird..Yes. No problems with the 1641 on the laptop used it on laptop for years. Actually the 800 fails more frequently on the desktop than the laptop.
Tried adjusting latency settings on the 800, but doesn't make any difference.
so you`ve obviously had the 1641 for a while, and its various drivers installed on both comps, then...installed the us-800 on both comps..
might wanna try wiping the laptop clean, then re installing the drivers for the us-800..
sounds like something is conflicting..
I`d like to think that most tuscam products are fairly reliable, as far as build quality..I`m sure theirs been a bad unit sent out here and there..but for the most part, I think 99% of problems people have, are not related to the unit it`s self, but rather the computor their installing it on..
I mean, why would it work perfectly on my computor which is also running on windows XP...but not your`s??
odd...
