How does one begin to fiddle with USB?

 From reading usb(3) I should have 
 /dev/usbm

but I don't

I've tried two different PCs with the same result

9% bind -a '#U' /dev
9% usb/usbd -dv
usbd: enumeration complete
9% ls /dev/usb*
ls: /dev/usb*: '/dev/usb*' file does not exist


Where am I going wrong?


usbsnoopy was pretty useless btw. it refreshes the window once per second which means you cant click fast enough to select a device and press install. It's a Visual Studio project and I don't have VC to re-compile it with a longer refresh. I found a shareware program that seems pretty good (30 days or 100 starts).

"Universal Serial Bus (USB) connects more than computers and peripherals. It has the power to connect you with a whole new world of PC experiences." - hmm

It's called `usb0' these days:

; ls -l /dev/usb0
d-r-xr-xr-x U 0 geoff geoff 0 Mar  5 22:00 /dev/usb0/0
--rw-rw-rw- U 0 geoff geoff 0 Mar  5 22:00 /dev/usb0/new
--rw-rw-rw- U 0 geoff geoff 0 Mar  5 22:00 /dev/usb0/port

Try
	ls '#U'

I missed that you'd already tried /dev/usb* initially.

Are you getting a '#U: ...' line when you boot?

Something else to check: do you have

	usb
	usbuhci

in the kernel configuration file for your kernel?

Is usb enabled in the bios?  Is there an IRQ assigned to it?
Do you have usb in your kernel?  Do you have an usb0=
line in your plan9.ini?
