USBs having trouble working
For the most part I haven't had any trouble with my USB ports but lately it seems like they don't have enough power to keep everything going, I have some audio things plugged in and only 2/3 seem to work at a time. First it was a MIDI Piano that wouldn't connect without a specific USB cord (but it worked with any cord on a different pc), now it's my Focusrite 2i2 when I plug it in no matter what cord I use it flashes on then off. I have a 750 watt PSU that seems like it would be enough. Even if I unplug some things the device that's having trouble won't work idk why this is at all, the support person for M-Audio told me it wasn't drivers but a USB HUB/Not enough power issue. Is there anything I can do to get more power?
