Okay. I'm buy four PS Eye Cameras. Usb connecting is good. 60 fps in ipi video recorder. Try to record the video on notebook and perconal computer. 4 cams. 2 to notebook, 2 to PC.
On notebook installed windows 7 x32, on PC installed x64.
After 2 minutes of recording I get message about this words:
ipi soft i/o system is too slow for video recording. On all computers
I think it is system overload the hard drive.
Okay. I open the task manager and close apps like torrent client and other possible.
It is not resolve a problem. Error is appear always.
What I'm doing wrong?

И так. Я купил четыре камеры PS eye. Скачал все драйвера. Дополнительный USB контроллер не помог для подключения всех камер к одному компьютеру. Дешёвый наверное, хоть и 2.0 реально. Ну думаю использую для 2-х камер ноутбук. В ipi recorder во время предпросмотра, все камеры захватывают видео без ошибок и drop frames. Всё отлично видно. Однкао при записи видео по истечении 2 минут выскакивает ошибка. Сейчас не помню. Что-то в духе. ipi soft i/o system is too slow for video recording. Причем и на мощном PC и на ноутбуке.
Я позакрывал все возможные процессы, но ошибка всё равно выскакивает. Установил optimization app не помогает.
Что я делаю не правильно?

Yes, this error means that disk drive's performance does not suit recording throughput. This error is usual when writing records to system disk, where OS is installed.
Write to another drive if computer has more than one, otherwise use JPEG compression to reduce throughput.

What's the problem with USB?
Modern desktop PCs have at least 2 USB 2.0 controllers which should be adequate for 4 PS Eyes at 60 fps. Have you tried different combinations of USB ports used to connect the cameras?

Thanx. Try to try it)
I haven't problem with usb.
Make it longer about one and two meters with usual usb cable. Have a litle shake. one for 2 seconds in one camera (where wire is longer).
Also for 3,4 cameras, I was expand wire with lan cable about 5 meters.
It is strange. On my modern pc its not works. But it works on 7-years-old notebook with usb 2.0 speed)
