Hi, i got my 4 ps3 eyes, and they seem not to work with usb hub, 5m passive usb extenders and even 2 connected 1,8m extenders(3,6m). So i think as it has 2m cable on its own, maximum passive extender would be 3m) Have to order active extenders.
According to my experience, at least with some hubs you can connect up to 2 Sony PS Eye cameras via a hub. Since there are so many different hub models on the market, it is hard to predict if particular model will work or not.
Most active USB extension cables are known to work well.

Also when i try to record a video with 640*480 resolution ipirecorder stops recording after a few seconds, even though the space on hdd is enough. But it works on 320*240 ok.
You have 2 indicators in iPi Recorder - for compression cache and for I/O cache. Which one of them runs out faster? If your compression cache runs out first, then your CPU is too slow to be able to compress video in real time for selected resolution and frame rate. If your I/O cache runs out first, then your HDD is not fast enough.
Please keep in mind that using system disk (the "C:" disk) for video recording is much slower then using a dedicated disk. Operating system performs lots of unpredictable disk operations on your system disk (like access to swap file) and this slows down video recording. Keep in mind that HDDs are mechanical devices.
If you have a desktop PC, consider installing second, dedicated hard drive for video recording. Most modern desktop HDDs are pretty fast and should be able to record video from 4 cameras at 640x480 at 60 frames per second without any problems.
If you use a notebook PC for recording, it may not be possible installing second hard drive. In that case, consider using SSD (solid state drive), like this one:
