Hang at POST screen with two USB devices connected

I'm trying to connect two USB devices to my TS200v:

  • a UPS (CyberPower)
  • a USB hub / card reader (integrated into a Dell monitor)

If I only connect one of these devices, the system boots fine.

If I connect both of these devices, however, the system hangs at the "ThinkServer" splash screen about 90% of the time.


I can't figure out how to get around this. I had no trouble using both of these USB devices with my last system.

Some things I've tried:

  • All kinds of port combinations (e.g. port 3 & 4, port 5 & 6, port 3 & 8, one device in front USB port & one in back, etc.)
  • Updating BIOS to latest version (5JKT51A)
  • Changing USB Legacy option in BIOS to Disabled


Any ideas?

Re: Hang at POST screen with two USB devices connected

Yes, I have the same problem.


I have tried all the different combinations of USB ports with a USB keyboard & mouse. How exactly is somebody supposed to use a keyboard and mouse on this server considering that there are no PS2 ports?
