Bullshit. USB is a relatively open standard and better still there are
standards covering most of the device classes it supports too. (example,
usb storage uses pretty much one driver for everything).
as to patents? well Im writing code for a USB device and I have official
manufacturer documentation sitting next to me too, freely downloaded...
If you want a closed standard to snipe at, try SecureDigital.

Wasnt called SCSI by any chance was it?

And then theres all the other busses that use SCSI-like protocols like

Actually USB neatly filled a hole. When it came out there was no
standard for common devices that only needed point to point,
single-master transactions, and there were multiple incompatible
standards for mice, keyboards, joysticks, etc.
it also had enough speed (well, 1.1 did) to be usefuil as a general
purpose serial link for comms devices, audio, storage...

No, it was (and successfully too) marketed to fill the 'one system that
will kill all the multiple different ports you dont need on the back of
seriously, I dont want a port for mice, a port for the keyboard, one for
my external storage device, all different. I like that I can plug in a
nice hub and split off three (or more) wires on my desk, avoiding the
massive tangle that used to live behind the PC.

What isnt? My PDA is, my mouse and keyboard are. My camera is. my wifi
cards are, and soon, I hope my digital TV receiver will be.

Works for me. I like hotpluggable storage (note that IDE caddies are NOT
hot pluggable, even if you do tend to get away with it), among other
I like that I can plug in any mouse and it just works. I like my PDA
synching at 12Mbit/sec rather than 56Kbit/sec over serial.
sure, its not gods gift to all problems - thats why my network is gigE
not USBnet, but its a bloody useful system.
