Before you buy it yes, you can't know.  But it's trivial to find out
after you own it.  For example click the Apple logo then choose "about
this Mac" and the data is there.  For example it says this random USB
thumb drive I have is

    Product ID: 0x3260
   Vendor ID: 0x0aec  (Neodio Technologies Corporation)
   Version: 1.00
   Serial Number: 20040602032741578

This same exact information is logged every time the device is
inserted to my Linux system too.  I assume MS Windows will tell you
all the vendor info as well.

The vendor IDs are handed out to manufacturers by an outfit at "usb.org".

So, check your devices.  It's not hard to find out about the ones you have.





This is pretty insane actually.
