*	tools/usbgen: extract driver names	Andrey Konovalov	2025-08-21	2	-39/+74
\| \| \| \| \| \| \| \| \| \|	Change the kernel patch and the syz-usbgen tool to split the extracted USB IDs by the driver they belong to. This will allow for a more precise patching of class/driver-specific USB descriptors. Also update USB IDs with Linux kernel 6.16.

*	sys/linux: extract USB HID ids (#1294)	Andrey Konovalov	2019-07-22	2	-34/+119
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	* sys/linux: extract USB HID ids As it turns out the HID kernel subsystem registers only one USB driver that checks that the interface of the connected device has HID class and then looks up its own list of vendor/device ids to find a matching driver. This means that we currently don't generate proper vendor/device ids for USB HID devices. This patch updates the syz-usbgen tool to also extract USB HID vendor/device ids from a running kernel and makes the generated descriptions for HID devices to be patched using the extracted ids. This patch also contains some minor improvements to USB descriptions (better HID descriptions and more replies for some USB classes/drivers). * sys/linux: run make generate
*	sys: add USB descriptions	Andrey Konovalov	2019-04-11	2	-0/+124
	This commit adds syzkaller descriptions for USB fuzzing. The descriptions in vusb.txt are written manually and cover different kinds of USB descriptors. The descriptions in init_vusb_ids.go are generated automanitally by the syz-usbgen tool and contain the vendor, device and some other IDs that map to different USB drivers.
