Are you having issues with the USB 3.0 when using BIOS v0022?
Thank you for your reply!
You mean to detach the battery cable for some minutes? I already found that workaround, but didn't try it, yet. The reason is simple, as I couldn't get the mainboard out of the case. It's kind of stuck - although I unscrewed both screws. I'll try it again, though.
But as I stated earlier, the problem occured AFTER flashing FW23...
Regarding the USB 3.0 issue, yes, that occured with FW22, too.
Also FW23 was released this week, the attached date states, that it was coded in December. So, do you perhaps have a newer beta FW I could try?
