Hello, I'm using dibusb driver, version CVS 9.April 2005 since a while very successfully. I noticed a lot of system instabilities when I habe an USB (2.0) hub between my notebook and the VisionPlus receiver. But it works perfectly when I connect it directly to the computer. I tried 6 different hubs, one of them was very very expensive. All of them have a power supply and in all cases I connected only my Logitech mouse to the same hub. Problem symptoms occur sporadically, sometimes many together, sometimes single symptoms and sometimes the computer runs stable for hours. - Some buttons from the keyboard do not work - WLAN gets a connection to the AP but cannot load any website - mplayer cannot find audio track on DVD - trancode cannot read the whole TOC of a DVD - System is very slow - dibusb driver reports timeouts on epin0 - If an USB harddisk is attached to the same hub, it looses often data but I did not write anything to the disk. Are you aware of those problems? Is a better solution available than avoiding the use of USB hubs?
