The device binds cleanly but delivers no image data; USB autosuspend is
suspending the streaming endpoint. Disable autosuspend for it.
Issue found on Lenovo ThinkPad X13 (codename Zelda, Intel); confirmed
working with this quirk.

Hi.
I think something went wrong when you pasted the text and also when you run it.
checkout: https://lore.kernel.org/linux-media/CANiDSCse5+Ke-Z2321F_QHJZX2suCKxnBy5WuNHE3m1wjoxX-Q@mail.gmail.com/T/#t
You seem to have run `lsusb`, not `lsusb -v -d 30c9:0122`
Can you try again?
Thanks!
