I would like to use this USB/IP idea to connect a DVB-T adapter to the N900.

But I also found a PCTV DVBT Wlan solution:

How do you think will this device transfer the streams? couls be a simple video stream over RTSP, or they could use something like a USB over IP solution.

I need the latter because ultimately I want to view pay-tv channels, so I need "direct" access to the DVB-T adapter in order to de-scramble the streams.

Same problem as Bernard

I also noticed the same problem and tried to debug the software. So instead of
usbipd -D
I started the daemon with
usbipd -d
to get debug information. And then usbip seems to work fine
Now I have virtually connected USB mouse on my PC. And also worked between two Ubuntu PCs. Haven't tried yet with N900.

I believe that -d or -D does not matter.
if the error occurs, you should kill the usbip deamon en restart it with the sudo usbipd -D command. after that it also works for me.
I also tested it on the n900, but that does not yet work. I do get a port 0 attached message, and there is a second USB device when I run lsusb, but when I look in output of dmesg, I see a lot of errors. (bad cable etc. etc.)

Maybe it was because I tried to send a USB stick to the N900, and maybe it lacks the proper drivers. I will try a keyboard and/or mouse tomorrow.

I have tried to use N900 as WiFi USB Server for a Windows Client but it not works.

• On N900 (Power Kernel v48) I have done:
  • Used h-e-n to power and enumerate an Usb Stick (full usb 2.0)
  • Connected N900 to Access Point
  • Loaded the needed usbip modules and started the usbip deamon:
    sudo gainroot
    modprobe usbip
    modprobe usbip_common_mod
    usbipd -D
  • Shared the Usb Stick:
    usbip_bind_driver --usbip 1-1
• On Windows (Seven x64 with UsbIp driver installed) I have done:
  • Listed remote usb device:
    C:\Users\xxxx\usbip_windows_v0.2.0.0_signed>usbip -l 192.168.x.3
    This works correctly and reports:
    - 192.168.x.3
    1-1: SanDisk Corp. : Cruzer Micro 256/512MB Flash Drive (0781:5151)
    : /sys/devices/platform/musb_hdrc/usb1/1-1
    : (Defined at Interface level) (00/00/00)
    : 0 - Mass Storage / SCSI / Bulk (Zip) (08/06/50)
  • Attached the remote usb device:
    C:\Users\xxxx\usbip_windows_v0.2.0.0_signed>usbip -a 192.168.x.3 1-1
    This not works, it hangs for some seconds and then it returns an error:
    new usb device attached to usbvbus port 1
    usbip err: usbip_windows.c: 374 (write_to_dev) read from sock ret 0 not equal a usbip_header
    

After the error something crashes on N900 because there isn't anymore shared usb device and the command lsusb hangs if executed.
I must reboot N900 to fix it

I have tried 2 o 3 times with different Usb devices, with always same results (and crashes)

Just came across your thread googling about usb over network solution.. Guys, have anybody tried http://www.net-usb.com/ in action?

I use the alternative solution to access USB over IP network - www.eltima.com/usb-over-ip/
The solution helped me a lot, but I bought it with the promocode and there was 30% off.

Yes, I did use it. It is Eltima Solution. It helped me a lot to access my USB devices over network.
