for the sake of troubleshooting can someone who has this issue please do the following:
1. Boot from the ESXi installation ISO
2. Press Alt-F12 on the keyboard as soon as possible to switch the screen to the VMkernel.log message display (This will work as soon as a message like "VMkernel initializing..." is displayed).
3. Wait until the keyboard stops working (on the log screen you can test if the keyboard is still working by scrolling left/right/up/down with the cursor keys)
4. Take a photo of the log screen and post it here.
I had the exact same problem as everyone else, but I am using an Asus ASUS RS700-E7/RS8, Here is what solved the problem for me:
See the attached photo, By default EHCI handoff was disabled, so I selected "Enabled" as shown and rebooted.
The keyboard and other USB devices then continued to be responsive. Some research into EHCI handoff is next on my list unless someone can shed some light on this subject.

Enable EHCI is the solution for me!
I enabled EHCI in the bios as suggested , and USB is working fine!
Alta3 Thank you for the sollution!
Solution for Intel S1200BTL motherboard.
Open the server case. Find USB port that is attached directly to the motherboard, it is near SATA connectors. Plug keyboard into it.
Voila, it works!
what to do when my bios doesn`t have the option "ehci".
I have options for IDE/AHCI/RAID , but no option for EHCI.
Same problem with ESXI 5.5.
5.1 is working ok!
EHCI is not an Hard drive option, but a USB option.
Normally you can find it under the tab "advanced" USB properties
Thanks varnav, worked for me on the S1200BTL
4me disable legacy usb and Port 60/64 Emu work. Both not needed for esxi (legacy usb is for dos and 60/64 for nt imho)...
S1200BTL using LSI Megaraid 9240-4i Raid card various issues (resolved) using Esxi 5.5
(S1200BTL has no EHCI option under advanced USB).
Esxi 5.5 would only instal when USB was plugged into the mainboard USB on the chassis directly and BIOS set to USB legacy: disabled and 64/60 Emulation: disabled.
Problem THEN would be: no keyboard input possible when ESXI was completely booted.
If keyboard was directly attached to chassis and the USB stick with ESXI was on the USB rear port it would hang on the *"Loading module megaraid_sas"* screen.
Solution for ALL problems: plug USB hub ONTO the chassis USB poort next to the SATA poorts and connect keyboard AND USB stick with ESXI onto HUB. everything works fine now.
I can confirm an issue with USB controller on S1200BTL board (BIOS 41 is the latest one). I was able to install ESXi 5.5 only with USB hub connected to internal USB port. UEFI Optimized boot enable doesn't resolve this issue also. ESXi 5.1 works fine. Obviously something wrong with USB drivers in 5.5.
Unfortunatelly I need more than one working USB port after installation. Because nothing changed even if installation completed and server beeted from internal storage, USB ports still doesn't work.
The interesting fact that all USB ports are connected to C204 chipset and should be at the same state, but they aren't.
Problem here, only one usb device is recognized in vsphere 5.5 the one is a ups from online usv, but my usb hard disk to make the backup does no longer working, strange
I am do the same thing on Intel s1200bts and it works )
I have the same issue.
After switching on the PC, the USB-keyboard works fine to enter BIOS and even to enter the ESXI recovery mode, but once the booting is underway or ended (yellow-black screen), I cannot enter ESXI SETUP-mode or QUIT, because the USB-keyboard isn't working anymore.
In addition I observe that VSpheres lists appropriate USB hardware on my motherboard, while Windows fails to find or install drivers, ie. for a USB CD-drive or ext.-HD-passthrough.
All I know is that I had it working once with the very same hardware. It's not the motherboard.
There must be some special setting in Spheres or in the relevant ESXI ini-files, no?
or maybe a boot parameter?
Publishing them here would be wonderful. Many thanks
