January 16th, 2015 here and STILL, nothing has been done about this error! I experience this on a somewhat consistent basis; the only workaround is to yes, shut down, then power back up and hope it re initializes the buggy/poorly coded VIA VL805 chip (in my case) to offer ANY USB 3.0 service. This is a major disappointment to see no one from either Gigabyte, nor VIA for that matter, seems to care. I'd post on their forums too, if it wasn't all in freaking Chinese...
I don't have an Intel board, it's an AMD one in my case, but the problem is EXACTLY the same; USB 3.0 functionality is completely lost upon some restarts, and then no restart will fix it! It ALWAYS has to be a shutdown, no sleep, just shut down and then turn it back on. I keep checking back to the BIOS page, hoping you guys release another version. I keep checking VIA's website at
www.via-labs.com for a newer version(they haven't updated it since July, 2014!). Please, please give us some sort of indication this is being looked into. Nothing in any case points to Microsoft being at fault, as I had an Etron USB 3.0 chip on my last board from you guys, and that one ALWAYS worked perfectly! This VIA problem seems to be a major issue all over the net, and I'm constantly reading about it being on GIGABYTE motherboards. Perhaps some hardware/software(coding) incompatibility on the mainboard? Oh, and I keep getting HAL errors about corrupted memory on sleep transitions every now and then; pretty sure that has to do with the VIA chip not playing nicely in the lowest 1 MB of RAM. I never got that EVER with the Etron chip. Hope you guys can email me or respond to this topic. Thanks, hope you had a Happy New Year too =)
