commit 0c243cd4a3671bf728f33378ac593c08d8367bc2 Author: Peter Grehan <[email protected]> AuthorDate: 2024-01-14 11:27:12 +0000 Commit: Peter Grehan <[email protected]> CommitDate: 2024-01-14 11:38:55 +0000 Fix issue with Linux guest XHCI tablet probing. The USB3 spec mandates that the device-descriptor max packet size be 512 bytes, which requires a field size of 9 since it is a power-of-2. Linux kernels recently started validating this field, resulting in the table not being probed and the cursor not working in bhyve VNC.
