Just playing with the plug again ...

Anyone using sd yet? usb disk?

I'm getting errors on each one .. probably pilot error.

You are probably interested in plan9 related issues, but you might be
interested in this as well: if you run cpu intensive stuff, the plug
will get hot. My plug practically killed 1 sd card and almost fried
another one as well. I have found several complaints on this issue.

I don't do anything too intense on my guru plug at the moment, and it seems
to run just fine.

I've not done much with the USB on it, but I was pleasantly surprised that
the JTAG serial doodad worked with Plan 9 to connect to the plug when I
couldn't get Mac OS X to use it :-)

can somebody post a boot serial console log with a working sd plugged
in? I'd like to see what I'm missing. I don't see the sd being
detected.

my sheeva says this:

192.168.2.3# cat ctl
enabled control rw speed high maxpkt 64 pollival 0 samplesz 0 hz 0 hub
1 port 1 busy
storage csp 0x500608 vid 0x1307 did 0x0163 'USB 2.0' 'Flash Disk' ehci
192.168.2.3# pwd
#u/usb/ep2.0
192.168.2.3#

(here is usb probe)

192.168.2.3# usb/probe
ep1.0 roothub csp 0x000009 ports 1 ehci
ep2.0 storage csp 0x500608 vid 0x1307 did 0x0163 'USB 2.0' 'Flash Disk' ehci
192.168.2.3#

Also, why do I see:
../ctl
../ep1.0
../ep2.0
../ep2.1
../ep2.2

What are the two extra endpoints?
192.168.2.3# cat ../ctl
ep1.0 enabled control rw speed high maxpkt 64 pollival 0 samplesz 0 hz

roothub csp 0x000009 ports 1 ehci

ep2.1 enabled bulk w speed high maxpkt 512 pollival 1 samplesz 0 hz 0

the manual says EHCI usb 2.0 are not supported; does this mean that I
can't use the above flash or is the manual out of date? Also my manual
shows U but /dev/drivers say u ... manual bug?

manually buggy.  :-)  the old usb driver was #U, the new #u.
fortunately the difference is only 0x20.

that's cause there's no sd driver for the onboard
sata or sd card.  it's on my short list.

the usb/disk is not a sd driver, but i think it could be if
usbd set things up and handed a generic sd scsi or ata
driver a channel to the usb device.
