KernelとUSB

古い話題だけど…。usbデバイスはユーザ空間でとか言われているけど、そうでもないという話。

Devices that use userspace USB drivers:

• Printers (CUPS)
• Scanners (SANE)
• Cameras (gPhoto2)

Devices that use kernelspace USB drivers:

• USB Mass storage (card readers/pendrives/media players/etc)
• USB Networking
• USB Bluetooth
• USB to serial/parallel converters
• USB HID Input
• USB Audio
• USB Video Capture

That USB devices are a userspace issue is a lie. They go both ways.

Besides, Trance Vibrator support is already in... the kernel.
