Re: [PATCH] usb: add QUIRK_NO_BOS for several devices
From: A1RM4X
Date: Wed Feb 04 2026 - 09:30:44 EST
Hi,
Please find attached the new patch which fixes the structure of the commit.
Why? If the option is not being used, the speed limit will be limited
to 5000M, which limits the capture capabilities of the device (4K30fps
at 5000M versus the expected 4K60fps at 10000M).
What happens in userspace?

* usb: add QUIRK_NO_BOS for several devices
- Disables BOS handling on devices that break when the BOS
descriptor is read (e.g. UGREEN 35871). Prevents the kernel
from falling back to a 5 Gbps link speed, unlocking the
expected 10 Gbps/4K 60 fps mode.
* usb: core: reorder BOS‑quirk entries alphabetically
- The three USB_QUIRK_NO_BOS entries are now placed in the
alphabetical order required by the file header.
