Here is a small example of USB devices enumeration I ended up putting together last nigh while browsing the ddk documentation. Perhaps it could be useful to someone.

p.s. tested on win xp sp2. with two double-port usb hubs. suggestions, comments are very welcomed? :)

It crashes right after displaying some info about the mouse (USB). I have 3 USB 1.1 hubs and 2 USB 2.0 hubs. 2 (of 3) USB 1.1 hubs are disabled.

The attached file is drwatson's crash dump and console's output.

Crashes here too, after this output:

nForce4 chipset (in case intel-vs-amd USB host controller standard matters), whole bunch of USB ports, etc.

Crash is somewhere in user32 (perhaps some string buffer overflow?)

ok, wasn't handling correctly devices with null control class code.
reattached fixed version.

Works now, cheers :)

I could be interpreting the data incorrectly but it looks like it cannot see the devices that are past the hub. It sees the hub okay, though.

rifleman, do you mean it doesn't sees any devices at all? or just a particular device connected to an external\integral hub?

a console dump + list of devices that you have would be helpful.

works fine here, xp sp2.. doesnt list units connected to the usb mass storage device though (ide->usb connector)..

If I am just reading it wrong, I am sorry. One Port is empty. The other port has a hub with a mouse and a memeory stick.

Paul,
Here is updated version which should enumerate external hub devices as well. I haven't tested it much, since I don't have an external hub.

evlncrn8,
Is it an IDE harddrive connected trough USB adapter? If it is, than it should be listed as a mass storage device (info regarding internal drive stuff, size, geometry, etc, wont be displayed).

Posted on 2006-04-19 19:22:10 by arafel

Arafel, would you mind putting a version number in the filename when attaching? Makes it easier to spot new versions :)

Posted on 2006-04-19 20:30:18 by f0dder

Arafel,
Did you forget the attachment?

Paul

Posted on 2006-04-19 21:38:12 by PBrennick

Paul I have updated the attachment in the first message. Sorry for all the confusion... From now on I'll just add new attachments in subsequent messages.

f0dder, ok, ver. info has been added.

Arafel,
Works like a charm, would you like to see a dump?

yes, yes, please post it :)

Holly bananas! f0dder, is there anything else on your system besides usb ports ? :mrgreen:

P.S. Seems like the text formatting got screwed up for nested hubs... Doesn't matter much though, because I am thinking about converting it into gui version anyway (..sometime in near future, when the damn middle-term exams will over and I'll have some more free time)

Posted on 2006-04-20 05:55:41 by arafel

Well, what can I say? nForce4 boards already has a *lot* of USB ports, and I've hooked a 3-port hub / 16-in-1 card reader up as well...
