Post by thread:[pic]: USB and Vendor ID

Hi PICList friends, I am trying to implement a USB interface using PIC16C765 and WinRT for USB new version for WinNT 4.0 (http://www.bluewatersystems.com/products/devtools/usbwin40/). I have a few questions regarding the software library that Microchip publish on their web site (http://www.microchip.com/10/lit/pline/picmicro/families/16c7xx/support/usbv110/index.htm). As I understand the USB world, then if we want to develop a USB device, then we need to get a Vendor ID from http://www.usb.org (http://www.usb.org/developers/data/usbifapp.pdf), but, they ask an annual subscription of $2500 for this Vendor ID. Is there a way around it ? Is the Vendor ID only needed in the Windows driver or it is also needed during the enumeration process and needed by the software library that Microchip provide? If it does needed by the software library, could someone please point me where ? Thanks Chaipi -- http://www.piclist.com#nomail Going offline?

Is there a way around it ? to develop a USB device for commercial use you will need a vendor id. it's a 16 bit number used at both ends of the wire to uniquely identify each manufacturer. the good news is that it shouldn't cost you 2500 dollars as you don't need to join the usbif. iirc the cost to just register for a vid is around $100... there's mention of it in the faq: http://www.usb.org/developers/usbfaq.html#3 if you are only using usb in a confined environment (i.e. you are not going to sell anything) then you could just pick any number and use that instead, just remember that some future device may come along and mess everything up for you.

Sorry not sure where but I think there are "test" ID's which can be used. Might pay to search the http://www.usb.org site a bit for it. -- ___________________________________________ Wesley Moore RMIT - BEng/BApp.Sc. 2nd Year wmooreKILLspamcs.rmit.edu.au http://wmoore.tsx.org/ -- http://www.piclist.com#nomail Going offline?

Chaipi: Non-members can purchase a VID for $200. Apply now; the USB-IF is sometimes slow. > Is the Vendor ID only needed in the Windows driver or it is also > needed during the enumeration process and needed by the software > library that Microchip provide? The VID and PID (Product ID, which you choose) identify your device to the host during enumeration; it's needed by the Windows INF file and by your device. > If it does needed by the software library, could someone please > point me where ? It goes in the Device Descriptor. -Andy === Andrew Warren - KILLspamfastfwdKILLspamix.netcom.com === Fast Forward Engineering - San Diego, California === http://www.geocities.com/SiliconValley/2499 -- http://www.piclist.com hint: The PICList is archived three different ways.
