[Elen Niedermeyer]

Dear Sir or Madam, 

I'm trying to run usbip-vudc since a few days. I want to access my emulated usb devices over usbip. 
I use Ubuntu 16.04.01 and updated my kernel to version 4.8.0-30. I've installed linux-tools-4.8.0-30-generic which includes usbip. I enabled the modules usbip-host and usbip-vudc on the server. Futhermore I use configfs to emulate the usb devices. 
So I could start the daemon and my emulation. But I can't detect my emulated usb device with usbip to bind it. 
Could you help me to run usbip-vudc? Do I have to install an additional package? Do I miss a step? 

Mit freundlichen Grüßen 
Kind regards,

Could you please send your dmesg? Also could you run usbipd with
--debug and usbip with --log option and send the syslog

Krzysztof,

Any ideas. Maybe it is time the documentation is updated with vudc details.

thanks,

You setup script should look like this:

Server:
$ modprobe usbip-vudc
# Create your gadget, for example:
$ cd /sys/kernel/config/usb_gadget
$ mkdir g1
$ mkdir g1/functions/acm.ser0
$ mkdir g1/configs/c.1
$ ln -s g1/functions/acm.ser0 g1/configs/c.1
$ echo "0x1234" > g1/idVendor
$ echo "0x5678" > g1/idProduct
$ echo usbip-vudc.0 > UDC
$ usbipd --device

Client:
$ modprobe usbip-vhci
$ usbip attach -r $SERVER_IP -d usbip-vudc.0

Please let me know if your setup script is similar and what exactly is
not working for you.

Yes I think it's a good idea. I'll try to do this when I have some spare
time.

Thanks Krzysztof. When you get around to it, let's just add it under
Documentation. You can create a new file usbip.txt (guess at some
point we have to make .rst)

thanks,
