Hello

I'm thinking that the following SVID values are defined.

>Discover Modes for Display Port SVID (0xFF01);

>Discover Modes for Apple SVID (0x05AC);

>

Q)

But Is there any material that explaining above code(xFF01, 0x05AC,,,etc).Also, PD3.0/PD2.0 standard document does not describe about the codes(ex. 0xFF01/0x05A, ,,,etc)

Best Regards

SVID is assigned by the USB-IF. Cypress does not manage it.

Please refer to VID list. http://www.linux-usb.org/usb.ids

SVID is used by USB PD Structured VDMs when requesting VIDs from a device.

On Discover SVIDs, the managed active cable shall return a list of SVIDs that it supports.

(Above descriptions are copied from USB Type-C Spec 1.3)

Is there anything else what would you like to know?

I investigated the USB Type-C Spec. 1.3, but I could not find where the SVID Value code was described.For example, I think 0x05AC means Apple SVID, but I can not find a description about 0x05AC.Please tell me about the document which is described code number and the explanation.
