| 1460614 | 2019-05-12 00:56:00 | How do I find out how many USB 3.0 controllers I have on my motherboard? There's 4 rear USB3.0 ports in total but I think they share controllers/bandwidth. When I plug in multiple high powered 3.0 devices (oculus rift headset and sensors) they sometimes drop intermittently or switch back and forth between 3.0 and 2.0 so I assume there isn't enough bandwidth. Page 14/103 shows a diagram of the layout: asrock.pc.cdn.bitgravity.com I'm assuming there's 3 controllers in total, 2 shared between the 4 rear 3.0 I/O ports and 1 for the internal 3.0 header on the right side (number 8). The official page (The official page doesn't say how many 3.0 controllers it has: www.asrock.com H97 Performance/) doesn't say how many 3.0 controllers it has. I'll probably buy one of these (www.pbtech.co.nz) to utilise that spare 3.0 header, but I still need to know whether the rear I/O ports share 1 or 2 USB controllers, how do I find out for sure? Connecting more than two sensors to a single USB 3.0 host controller can cause sporadic behavioral issues and lost sensor data, which affects tracking quality and your VR experience. www.oculus.com |

| 1460615 | 2019-05-12 02:51:00 | Try device manager/ universal serial bus controllers. Look for eXtensible host controller. According to the way I read it your H97 chipset has one ark.intel.com |

| 1460616 | 2019-05-12 06:01:00 | I've only got one of those, does that mean even the internal USB3 header shares the same controller? 5gbps bandwidth shared between all USB3 ports? | Vicx (11114) | ||
| 1460617 | 2019-05-12 07:46:00 | the H97 chipset can handle: # of USB Ports 14 USB Revision 3.0/2.0 USB 3.0 6 USB 2.0 8 As stated in the following ark.intel.com Did you check device manager/ universal serial bus controllers like I suggested? |

| 1460618 | 2019-05-12 07:51:00 | Unless the motherboard has other USB 3 controller chips, the lot will be through the H97 chipset You could try adding USB 3.0 pci-e add in cards, but their bandwidth will be limited by the number of pci-e lanes available |

| 1460619 | 2019-05-12 08:45:00 | I've only got one eXtensible host controller in device manager, what else am I looking for? Making use of that internal USB3 header won't make a difference will it? | Vicx (11114) | ||

No it won't, I would'nt think. You could try a USB 3 pci-e add-in card, but the max bandwidth of pci-e 2.0 x1 is around 4 Gbits/second |

| 1460621 | 2019-05-13 13:48:00 | I found a PCI-E card with 10gbps but my spare slot is 2.0 which is only 5gbps but it's better than nothing I guess. My motherboard accepts PCI-E cards but it doesn't look like the first PCI-E slot can accommodate the card, the pins don't seem to match, what do you think? www.startech.com |

| 1460622 | 2019-05-13 22:52:00 | I don't think the rift needs all that much bandwidth and from memory setting mine up some of the connections are able to use USB 2 if necessary. But I have a lot more ports than you so I've never had to find out. Maybe a powered USB hub might help, but one of those cards should work too. Depends if the issue is bandwidth, power, or driver related. It might be worth installing the latest drivers from the motherboard manufacturer as I don't think it's supposed to ever drop back to USB 2 regardless of what's plugged in. I would expect it to still be USB 3 and just run slower if there were bandwidth issues. Also it could be a physical issue with the plugs, maybe some pins are not making good contact. I think USB 3 uses more connections. |

| 1460623 | 2019-05-13 23:43:00 | I used to use 2x 3m extension cables for the sensors but as I started improving in Beat Saber I realised the tracking was a bit delayed as I started playing faster so I upgraded to 3m 3.0 cables but then I needed a USB hub to act as a repeater, without it they kept dropping out. I still get some intermittent skips in game and I don't know if it's caused by the bandwidth, but I was told it's not a good idea to use hubs as repeaters for either the HMD or sensors, so I'm wondering if buying a PCIE card to spread the bandwidth load might help and provide more power so I don't need the hubs. I've updated my drivers so I don't think it's that. I'm upgrading my HMD's 3m cable to 5m so I'm probably going to need more bandwidth or power to the PCIE card. | Vicx (11114) | ||
