Well there it is. I'd bet your total hashrate stays about the same. That problem was looked at in the first few pages of this thread, I believe.
Wonder if it is only a Win10 driver issue.
Moved three of them to an old Win7 laptop and they are averaging 105GH/s at 250mhz,
while the one on the win10 is up to 88gh at 200.- - Update, after a reboot of the win10, all the devices are now at 100gh/s or better.
Edit 2: All 5 now running on the Win7 Laptop and doing 100+ so issue is either win10 or the usb controllers on my desktop's motherboard. Perhaps it is due to modem boards only have one USB2 controller, as mine has mostly 3 and 3.1 controllers, and the laptop has two usb2 controllers on opposite ends of the mobo.
Overall impression: These are incredible little miners! Got 5 hashing away hassle free no overnight zombie like the old antminer u series. Have bought 6 so far, one has an issue sidehack is going to fix for me when I send it back to him, but the other 5 are mint. Buying direct the price is great, and the service is unmatched.
Next DIY project for me, I'm going to build a mount for 6 of the Miners, and take advantage of the heat sink design to create a air tunnel fan intake/exhaust setup to add extra cooling for the summer.
