Class 1 - Audio
|
|
|
|
|
This class contains audio devices such as amplifiers, receivers, music
instruments, recording and play-back devices. At present, there is no
support for these type of devices on RISC OS.

Class 2 - Communication Device Class
|
|
|
|
|
This class contains communication devices such as Analog Modems,
ISDN modems, Telephone sets, Ethernet control, ATM control, etc.
In practice however, most communication devices have a
vendor specific interface.

Class 3 - Human Interface Devices
|
|
|
|
|
This class contains Human Interface Devices, such as Mouse, Keyboard,
Tablet, Joystick, Barcode reader, etc. It is by far the most popular
USB class. Basic support for keyboard and mouse is present in the
RISC OS kernel, but for additional features, our
USBHID module is recommended.

Class 7 - Printers
|
|
|
|
|
RISC OS contains native support for most standard printers connected
via USB. This includes old printers with a Centronics interface that
are connected via a special dongle.

Class 8 - Mass Storage
|
|
|
|
|
This class contains nearly all storage devices, such as harddiscs,
card readers, flash drives, external floppy drives and even some cameras.
RISC OS currently only supports class 8_6 (SCSI), but this includes nearly
all current storage devices found on the market today.

Class 9 - HUB
|
|
|
|
|
This class is the most common one as it will be found on virtually
every computer supporting USB. Any interface card with more than
one USB port on it contains a Hub and further Hubs can be cascaded
to allow more devices to be connected.

Class 10 - Data Interface Class
|
|
|
|
|
This class contains a wide range of devices that can be used for
streaming data, such as webcams. Many different protocols and transfer
modes exist in this class. Unfortunately, most data streaming devices
used the vendor specific class.

Class 255 - Vendor-Specific
|
|
|
|
|
This class contains devices that do not fall into any other
class and devices with the vendor-specific interface and/or
protocol. Support for such devices under RISC OS is very
unlikely, as it requires the cooperation of the manufacturer.
Her are some examples of devices we have seen:
