Hello all,
have not been able to find a solution to this error
My aim is to run 6 pseye cams from my laptop. I have 3 usb ports, 2 x 2.0 and 1 x 3.0.
connecting all the cams individually (so 3 at any one time) works fine. However, when I connect two to a USB hub, the ipi recorder come up with the error 'Control Transfer Failed'
This happens if I have just 2 cams connected in one USB and none in the other two.
in device manager it is recognising all cameras as ps eye cams, as is the case in the ipi recorder camera selection, so they are recognised as connected. If i connect just one cam through a USB hub, that works fine.
It seems there is some issue with the USB controllers or the ipi recorder setup.
I have read that usb controllers for 2.0 don't always deal well with more than 2 USB connections, so I have put one cam in each of the usb 2.0 ports and tried multiple cams in the usb 3.0 port but even the usb three port comes up with this error with just two cams connected to the USB hub. I have 3 USB hubs and is the same on each.
Other thing is that when I connect two of the cams through a USB hub and on in another, in the camera selection in the ipi recorder it says under each of the cams: 'Warning! more than 2 cameras connected to the same USB controller #1'
this is the same whichever ports I connect the cameras to. If i connect one in each of the ports, it doesn't show up, which suggests that both controllers are working. This message always says #1 for all port connection setups.
I remember before, using windows 7, that i had to connect 4 cams to the usb 3.0 port and one in each of the 2.0 to get all 6 working ok, but this doesn't seem to work with this windows 10 computer, which is much higher spec.
the usb drivers I have are: Intel(r) 8 series/C220 Series USB EHCI #1 - 8C26 Intel(r) 8 series/C220 Series USB EHCI #2 - 8C2D Intel (R) USB 3.0 eXtensible Host Controller - 1.0
is a lenovo y70 laptop, the 17inch touchscreen model with 16GB Ram, core i7 quad core processor and 2Gb nvidia gfroce gtx 860M (or 870M) and 500gb SSD HD
Are there some settings somewhere in the ipi recorder or my usb controller settings that will resolve this issue?
many thanks
Rich
