I have a question regarding USB hubs. I have purchased a hub that goes into the 5.25 inch slot on the front of the PC case and connects to the internal USB3 header on the motherboard. The PC case originally had 2 USB ports on the front, that were connected to the internal USB3 header. I have disconnected those and connected the newly bought hub to that header.
However the USB3.1 ports on the new hub dont work, when I plug in a flash drive, nothing happens, Windows doesnt seem to notice the drive has been plugged in. When I reconnected the old USB3 ports, they worked still, so I think that should rule out the possibility of damaging the internal header when I was removing the cables/connectors.
I have tried the hub in a different (newer) PC and there the USB3 ports on the hub worked correctly.
Despite the title question, Im not entirely certain which USB version is supported on the older motherboard, as I couldnt find a proper spec sheet.
The PC is HP Elite 7300 MT, running Windows 7, CPU i7 2600, 16GB RAM, GPU GT 545.
The motherboard model is (according to CPU-Z):
Pegatron Corporation 2AB5
Best spec sheets I could find are here:
(this site worked yesterday (15. march) but seems to be down today)
UPDATE: the site came back on, so Im adding a screengrab in case it goes down again. Pegatron 2AB5 specs
UPDATE: this HP site probably is not the exactly same model and should be disregarded
The USB hub in question is Akasa AK-HC-11BK, specs here:
And the other motherboard (where the hub works) is Asus B85M-G, specs here:
Could it be because the newer PC has support for USB3.1 and the older one doesnt? So could it be that a motherboard that only supports USB 3.0 doesnt work with USB3.1 hub ? But shouldnt the hub just operate at 3.0 speeds in that case?
When searching on the internet, I have only found the opposite situation, people asking if USB 3.0 hub will work with 3.1 motherboard.
UPDATE 2: The original USB ports on the front panel are blue and have the SS USB symbol next to them. I have tested copying a 2.5GB file from a USB flash drive (Kingston Data Traveler 3.0 32GB, https://www.kingston.com/datasheets/dtr30g2_us.pdf) . When copying from the flash drive to a mechanical hard drive using the original front USB port, Windows reported a consistent speed of around 138MB/s. Thus it seems that the original port is indeed USB3.0 at a minimum.
Here is what the device manager looks like. This is when the original front panel USB is connected and 2 of the Akasa's USB2.0 ports are connected (using a single 9-pin cable to the motherboard) Device manager
It lists the Texas Instruments XHCI Controller.
I have put the serial number in HP support site (per telcoM's suggestion) and it does list Texas Instuments USB 3.0 XHCI Host Controller drivers.
I will try to install them and report back.
Update 3: There were 3 drivers listed on the HP site. After installing either one of the two newest, even the original USB port didnt work. After installing the oldest one, the original USB port started working again, but the Akasa's still doesnt.
