Other USB Devices Disconnect during & just after BIOS POST
on March 24, 2016
1) Nice stable flat design
2) 10 USB 3.0 ports, sweet!
1) With this device connected, I am seeing other connected USB devices to the main motherboard USB ports are disconnected during and just after BIOS POST. So I have no working keyboard during and just after BIOS POST, until the operating system starts to boot, whether Windows or Linux is booting.
2) On power down or shutdown using the operating system's commands, the computer will automatically restart after two to five seconds! A script within Linux will prevent this, "for i in /sys/bus/usb/devices/*/power/control; do echo on > $i; done"
Unfortunately with CON #1, I am probably going to have to return the device and buy another manufacturer's USB 3.0 hub. I've fiddled with other BIOS options, and nothing seems to resolve the missing attached USB devices during boot except unplugging this hub from the computer.
I have tried connecting this device to other motherboard USB ports, with different manufacturer USB-3 chips (ie. Intel, VIA, ...); and even playing with BIOS settings, still nothing seemed to resolve the problems. Either I've received a defective unit, or the unit became defective within a few hours of usage, I don't know. I'm shocked an Amazon.com device has this many problems, as I've absolutely never witnessed an Amazon.com device having such problems in the past. Amazon.com has always apparently had an excellent quality assurance rating up until my experience of using this device.
NOTE: Can't give the device just one star, as the shipping and boxing are superb. I'm thinking the problem might lie with bad capacitors (or similar) within the power supply or elsewhere. Maybe putting such a load upon the motherboard USB hub, other devices self-disconnect until adequate power is supplied through the USB-3 ports after the drivers are loaded? Think I'm also seeing the USB device being connected through USB-2 hub driver devices, instead of USB-3 hub driver devices. Shrugs.
