USB Gadget Vendor ID

USB Gadget Vendor ID

[Adriana Kobylak]

Hi Eddie,

I have a script to initialize the USB gadget for Virtual Media and there 
was a comment that the Vendor ID should be provided by the Linux 
Foundation - 
https://gerrit.openbmc-project.xyz/c/openbmc/meta-phosphor/+/17494 .

In your ikvm script you use a Vendor ID with the comment "Linux 
Foundation" - 
https://github.com/openbmc/obmc-ikvm/blob/fb6a8e1e727a8ece5eb0350d3962dd3056a6f608/create_usbhid.sh#L18

Is this an ID that came from the LF, and if so could I use it in my 
script?

As a side question, were there any discussions about the serial number 
value in the ikvm script? I have a similar hard-coded value for the 
virtual media one but there were questions in the review about how 
useful could it be having a non-generated value and to have it removed 
instead.

Hi,

Since OpenBMC is a LF project, I just used their vendor ID... and I just 
invented a serial number. This might not be the proper way to do it... 
Since the devices are virtual, I'm not sure anyone will care though?

I think there were similar comments about the serial number but in the 
end it was decided to worry about it later I think.

Thanks, Eddie

Thanks that helps. Forgot to ask about the the product id (echo 0x0104 > 
idProduct # Multifunction Composite Gadget), is it also a LF number or 
documented somewhere?

Yes, here's the list I was using: http://www.linux-usb.org/usb.ids
