Hi everyone,
I would like to ask you for help. I have a bad habit of using several external 2,5' (and one 3,5') drives. I kind of accumulated these over years and I stopped using them for "mobility" purposes (nowadays lot of things is in cloud etc).
At first I used to connect them via USB 3.0 extending cables, but this was not very feasible due to many cables on my desk (I was using 4 or 5 disks), most of ports in the back of the case being occupied and I rarely used more than 1-2 disk at any given moment (I used most of them throughout a day let's say).
I then came with an idea of a USB hub that would only occupy one USB port. I could live with a fact that total throughput of disks combined would be lower. The USB hub would be (or should I say is) AC-powered so that there is no problem with the power supply. However shortly after realizing this scheme I came to a problem.
Sometimes (I could not pinpoint the direct cause but I have some examples) when I start the machine, the BIOS shows no keyboard found and only after the Windows has booted, all USB ports are working fine. USB keyboard is on a separate port of course (not connected to the hub). I basically use 3 USB ports (1x keyboard, 1x mouse, 1x HUB with 3-4 devices). I thought that maybe the problem was that one of the disks (one that is 3,5') has it's own AC-power supply and I am creating some king of electricity loop which haywires some "stuff" in motherboard. But it's not the case. Even when the 3,5' one is not connected the problem still persist.
The problem manifests when the computer is off for a longer time, or there has been power outage, or BSOD. When I am restarting from Windows gracefully, the problem does not occur.
I have Asus P8Z77-V LK motherboard with BIOS revision from 2012 (most up to date is 2014). The USB hub is https://www.google.cz/search?q=I-TEC+USB+3.0+Metal+Charging+HUB+10+Port. It probably somehow relates to motherboard having problem with the hub (perhaps the BIOS) because after USB drivers load in Windows there is no such error. But then again, if motherboard had problem of not being able to recognize the hub or work with it, it would not work all the time and only sometimes.
So ... the question is: has anybody a similar experience or what would you advise?
PS: I have a third "scheme" in my mind for the future, but I am not sure how feasible it will be. I could put the disks in some kind of a hardware enclosure and make it either a RAID or simply having them connected to a hub directly via SATA/IDE instead of USB. However it could lead to a similar result of a motherboard / BIOS having problem with controller of such hub.

John
