I have a set of HP Z210 Workstations with E3-1245-V2 Xeon Cpu's, SSD boot drives and varying sizes of memory from 8-16GB 1600Mghz DDR3 ECC. We use Windows 8 Enterprise for these machines, with Hyper-V enabled.

We get regular driver failures from the 2 sets of USB controllers on the machines (Mainly and issue for the KB & Mouse) that can only be resolved with a full power down (not restart) and a power up. This happens at least once every 1-3 days per machine.

I had gone through the HP support, but they have advised this isn't an issue on their side, and I had agreed all along. I was just hoping to get some traction by notifying them. Anyway, after a lengthy trouble shooting session, we found that once Hyper-V was enabled, the fault arose.

As it was an Intel chip, they I asked them. They advised that on Windows 8, the drivers are supplied via windows update and that it was not their issue.

So, how can I get this resolved? Not through HP or Intel, surely through MS? Maybe not. Disabling Hyper-V is not desired as I the teams with these PC's are developers and require local visualization. Also, we have templates ready for Hyper-V, I don't really want to remove Hyper-V and use Virtual box or VMWare workstation. but I am at wits end with the fault and lack of help from the vendors.

Please help.

Having the same issue here. i removed hyper-v to stop the driver from failing, was rather annoying as my mouse/keyboard were hooked into that controller.

I have found a work around for this fault with the USB failure - ENSURE YOU POWER  THE MACHINE OFF - DO NOT RESTART.

Its almost like the restart doesn't initialise the device correct, thus causing a failure.
