'How does adb find the USB port #?

When I run "adb devices -l", it is able to display the USB port info as "usb:xxxxxxx". Does anyone know how adb pulls this info? I'm trying to figure out how I may be able to do this with idb so I can get the same USB info for the attached iPhones. Thanks!

On macOS you can use

ioreg -p IOUSB

and it lists something like

| +-o your device (2022)@14400000  <class AppleUSBDevice, id 0x0...>

and if you convert the hex to decimal

0x14400000 => 339738624

it's the number displayed by adb:

XXXXXXXX             device usb:339738624X product: blah, blah

you would use the command "lsusb" on Linux and MacOS
