Title: VID or PID of 0000h (zero)?
Post by: USBVIDPID on August 27, 2012, 10:50:47 am

Hello.

Is there any problem in using a Product ID of 0000h?.  How about a Vendor ID of 0000h (zero)? (I understand that the USB-IF assigns VIDs).  Or is the minimum VID and PID = 0001h?

Thanks, jmw

For in-house testing, use any VID/PID combination that doesn't conflict with the VID/PIDs in the system's INF files. I would avoid VID = 0000h.
