As I said, I reckon it's a mobilephone-type device. Anyway, I googled
r8152 wwan (from your output) which hits
https://android.googlesource.com/kernel/common.git/+/bcmdhd-3.10/drivers/net/usb/Kconfig
on which r8152 tells you about Realtek RTL8152 Based USB 2.0 Ethernet Adapters
and wwan tells you about Sierra Wireless USB-to-WWAN device.
Sierra wwan then gives you stuff about 2/3/4G broadband.
(Of not much interest to me.)
Cheers,
David.
