So I've been using a Modi for awhile now on my computer which hasn't gone through any recent changes. However the DAC started to fail a couple weeks ago. Upon turning on my computer, it would simply be undetected, and I would have to play a game of unplugging it, and plugging it back into various USB ports and this would usually resolve it. However as the week went by, one day it simply failed to detect properly no matter what I did. At the time, I assumed this was likely a power issue so ordered a Wyrd to resolve this. And sure enough once I got it and put it in, it immediately started to work again. However the next time I powered on, I was faced with the exact same issue. It wasn't detecting, and I had to unplug, turn it off/on, and try different ports until it magically detected. But now a few days later, no matter what I do once again it is no longer detecting. It seems as if Wyrd is detected fine, as I get the generic usb hub installed message, but then its followed by "installing device driver software" then "....was not successfully installed." My next thought is to think something might be wrong with the DAC itself, but I've test it on my Macbook as well and it seems to function perfectly fine on there, even running off of USB power only. Subsequently aside from the DAC failing, my USB ports seem to be fine. I've tried plugging various other peripherals into them, and they seem to function without issue. At this point, completely at a loss at what to try next. So any thoughts/ideas on the matter would be appreciated.
