USB Connection time and transfer speeds

Specs: Windows 7 SP1, Intel core i5-4690 Haswell refresh / DDR3 Ram 8gb Hyperx beast 2400mhz
I have a new home built PC but I'm having some USB related issues. When I connect a memory stick it takes several minutes before it shows up in My Computer and it just shows the loading indicator at the top of the screen. Once it's loaded it works fine but it gives me poor speeds sometimes 3.3mbps. The port is USB3 and the memory sticks are USB3 as well. Here are the speeds I'm getting on two different memory sticks (I got these from running a Nirsoft USB tester program):

PNY 32gb USB 3.0 (FAT32)
- USB 3 port = 24.24 MB/sec Write, 40.36 MB/sec Read
- USB 2 port = 24.45 MB/sec Write, 40.63 MB/sec Read

Kingston DT-SE9 USB 3.0 (NTFS)
- USB 3 port = 5.30 MB/sec Write, 24.00 MB/sec Read
- USB 2 port = 5.31 MB/sec Write, 20.19 MB/sec Read

(But today I was getting only 3.3 MB/sec for the PNY on USB 3.0 in practice. I understand the the speeds of 24-29mbps could be normal for USB 3.0.)

Other Specs
Gigabyte GA-Z97M-DS3H motherboard
Cooler Master Silencio 550 Silent Tower Case - White
Windows 7 64bit Professional (build 7601 SP1)
AMD Radeon R7 200 series
Intel i5-4690 Haswell Refresh 3.50ghz
8gb DDR-III ram

Ideas
I think it could be:
1) The motherboard
2) A faulty USB3.0 case connector (plugged in properly.)
3) Windows 7
4) BIOS configuration

This is my first complete home build so I'm a bit worried I've done something wrong but the PC otherwise works.

When you plug your 3.0 USB stick into the 2.0 port, does windows prompt you that your device would run faster if you plugged it into a 3.0 port?

Yes it does do that.

Did you install the motherboard drivers that came on cd with the motherboard?

Yes all drivers have been installed, and latest versions installed from the website.

Update: I tried to reinstall the USB 3 driver again to be sure then did a restart. I plugged in the PNY stick again and guess what? It gave me that message, this device could perform faster... but it's in a USB 3 port so what's going?

So you installed this Intel USB 3.0 driver?

Are you plugging your USB devices into the blue USB ports in the motherboard rear panel?

Yes I installed that driver.

I'm using the memory sticks on the front panel. It has 1 x USB 3 and 1 x USB 2. I could try the back panel in order to rule out the front ports as an issue.

Actually the time it takes to show up in My Computer varies stick to stick I've. On the PNY (FAT32) it's quick (several seconds), on the Kingston (NTFS) it's slow (1-3mins). I did a scan of the stick but Windows says it found no issues with it.

If you have an Antivirus installed, it might be slowing it down from being recognized in My Computer. But I don't know why that would effect the speed test you do later.

When is the last time you reformatted the Kingston drive?

I formatted and defragged the drive, no difference.

So it could just be the Kingston NTFS drive assuming that the transfer speeds above are otherwise normal.

UPDATE
I did a benchmark on the memory stick at userbenchmark.com and guess what? The Kingston is a USB 2 stick! It doesn't even say on the product description and with the capacity and launch date it looks like a USB3, mental. It still doesn't explain the connection times in My Computer.
