Windows 8 Login Screen - Mouse/Keyboard Stop Working

This is clearly a massive issue with Windows8, i have had it with microsoft...this will be my last windows PC, windows8 is the worst OS and probly programmed by chimps. I would also like to report this issue of mouse keyboard stop working on the metro clock/start up screen. Unable to enter password to access the PC i was forced to access the recovery mode/safe mode via the OS disk(yeah good job that...making safe mode only accessible via a bootable disc you morons). Upon entering into recovery mode none of the repair options worked nor could i do a system restore, the last restore point was a windows update only a half hour before the final shutdown and appearance of this issue. I was forced to do a full OS re-intall, and i am merely waiting for this issue to rear is ugly head again, as microsoft are sitting on their big fat baboon ****'s without clue. This was a brand new pc not 2months old, Intel® Core™ i5-3470 Processor Genuine Windows® 8 64 bit 1GB nVIDIA GeForce™ GT 620 8GB DDR3 1600MHz Memory 1TB SATA III - 6GB/s 7200rpm HDD Great job you **** amateurs

Still no real fix for that problem? :/

Most of the symptoms seem to indicate a problem with power for USB devices.  Coincidentally earlier this week I managed to hang W8 while booting by having a USB Flash drive in an unpowered USB hub (I was trying to save wear and tear on my laptop's USB ports).  As soon as I pulled the unpowered USB hub I was able to boot without any problem.

I would say its more of an issue with w8. I have had mouse and keyboard work fine in bios and as soon as it boots to windows I loose them. Never had the issue with Windows 7 and my issue started 3 days after upgrading.

The issue is always the same for me and to solve I remote desktop in to the PC, go into device manager and uninstall the following

Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller

Then right click and do Scan for hardware changes. This reinstalls and my mouse and keyboard comes back straight away.

For all of you out there, here is what works for me, after looking on the net for hours I was searching for the blackscreen fix and here it is:

• kill your computer

if you have any kind of switch on the sockets, where you have plugged it in, just turn it off.

I know, that this is not a "good" fix, but for me and a friend of mine, it worked.
