Hello, I'm in a situation where I need to plug 24 high bandwidths USB devices into the same machine (they're DSL modems actually).
I'm using 6 hubs, 2 of them plugged directly on the PC, and the fours others on the first hubs. Every hub has in turn 4 devices plugged in. The trouble is that all the bandwidth is soon taken up, in ISO mode I get "usb check bandwidth would have failed" messages, and in bulk mode, thousands of "ENXIO" messages. I determined that I can safely plug up to 8 modems on this setup, and after that the USB bus collapses. So I think I'm gonna use 2 additional PCI USB host controllers, if that means each of them has its own bus and bandwidth. Can anyone confirm that I'll have indeed 3x12Mbps, and can usb-uhci/usb-ohci/uhci handle this setup ? Thanks a lot... ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
