+ Userspace access to USB devices is granted by device-nodes exported

+ core and udev needed additional class devices to export device nodes.
+
+ These additional devices are difficult to handle in userspace, if
+ information about USB interfaces must be available. One device contains
+ the device node, the other device contains the interface data. Both
+ devices are at the same level in sysfs (siblings) and one can't access
+ the other. The device node created directly by the usbdev is the parent
+ device of the interface and therefore easily accessible from the interface
+ event.
+
+ This option provides backward compatibility if needed.

- /* Designer's Reference, p. 8 - 10 says we should Initate R_USB_FM_PSTART to 0x2A30 (10800),
- to guarantee that control traffic gets 10% of the bandwidth, and periodic transfer may
- allocate the rest (90%). This doesn't work though. Read on for a lenghty explanation.
-
- While there is a difference between rev. 2 and rev. 3 of the ETRAX 100LX regarding the NAK
- behaviour, it doesn't solve this problem. What happens is that a control transfer will not
- be interrupted in its data stage when PSTART happens (the point at which periodic traffic
- is started). Thus, if PSTART is set to 10800 and its IN or OUT token is NAKed until just before
- PSTART happens, it will continue the IN/OUT transfer as long as it's ACKed. After it's done,
- there may be too little time left for an isochronous transfer, causing an epid attention
- interrupt due to perror. The work-around for this is to let the control transfers run at the
- end of the frame instead of at the beginning, and will be interrupted just fine if it doesn't
- fit into the frame. However, since there will *always* be a control transfer at the beginning
- of the frame, regardless of what we set PSTART to, that transfer might be a 64-byte transfer
- which consumes up to 15% of the frame, leaving only 85% for periodic traffic. The solution to
- this would be to 'dummy allocate' 5% of the frame with the usb_claim_bandwidth function to make
- sure that the periodic transfers that are inserted will always fit in the frame.
-
- The idea was suggested that a control transfer could be split up into several 8 byte transfers,
- so that it would be interrupted by PSTART, but since this can't be done for an IN transfer this
- hasn't been implemented.
-
- The value 11960 is chosen to be just after the SOF token, with a couple of bit times extra
- for possible bit stuffing. */
