content: If we leave out of options ICs that are available only on certain consumer eshops (likeGL850G-HH and SL2.1A) what could be an option to include USB hub in circuit? I think one of those chips that has preprogrammed vendor id is USB2412, but that is pretty much the only one I have found (available on Digikey/Mouser).sw guy

content: You're still leaving us guessing here.How about an SSOP16 USB2FSHS hub, it's about as simple as it gets: Terminus FE8.1https://aliexpress.com/store/1100386256/search?SearchText=fe8.1Example schematic:https://github.com/ataradov/usb-sniffer-lite/blob/main/hardware/output/usb-sniffer-lite.pdfNo programming required.Edit: apparently this device is actually HS capablehttps://terminus-usa.com/product/fe8-1-usb2-0-high-speed-4-port-hub-controller/

content: Of Microchip products, only the USB2412 series has a fixed configuration (it was designed by SMSC), and is the cheapest option at Mouser (2.36€ in singles for USB2412-DZK, as usual for high-speed USB 2.0 hubs you need a 24 MHz crystal and a smattering of passives also).For open source products, there are alternatives; but, if you want USB-IF certification or write your own Windows USB signed drivers, I think you're going to have to pay theUSD $6000 for a Vendor ID. Note that because that legal entity cannot sell Product IDs, it is best to make sure the business entity buying such a Vendor ID can design and implement many other USB interface devices; there are, after all, over 65 thousand Product IDs per Vendor ID.For example, if you have your own Vendor ID, you can use it for any native-USB microcontroller projects (including super-cheapies like CH55x) you –– that same legal entity –– create, commercial or open source. In Finland, I'd definitely have that stuff in a wholly-owned subsidiary, so that it can sell such design and implementation services for others as well; noting that the name initially associated with the USB Vendor ID will stick "forever": it is not like web certificates with their revocation lists and updates, USB Vendor IDs are forever.

content: FE8.1 is basically what I am looking for (or GL850G-HH or SL2.1A), but Aliexpress/Ebay etc. is not option for a vendor channel.Fortunately there is one option at least (for this application). Unit price (of the chip) is not a limiting factor (as long as the USB controller is <$10), but 6k initial cost is a limiting factor.Private vendor IDs would be nice - the same way as IPs and MAC addresses.sg
