Default Re: USB 1.1/2.0 Implementation

Hey,

Sorry, my cheapy supernews account doesn't support attachments or .jpgs.
(text only)

The Jongo stuff sounds cool if it would work. I'm not going to be able to
rebuild our driver for awhile. I'll have to find the machine at work that
has the DDK installed. (My machine doesn't)

Interestingly our vendor/device id's don't exist in the driver source, only
the driver name.

Is Jongo free? Sounds interesting. I was wondering why there isn't a
generice bulk interface driver in Windows that you could use to talk to any
USB device. I'm wondering if its not possible. If our vendor/device id's
are only in our .inf file then that would mean anyone could map their device
to use an existing driver just by editting the .inf file.

As you may guess, I wasn't the guy who originally built our sample Netchip
driver many years ago. (I was the guy who got the registered ID's in the
first place) I know it was easy and it works great. I'll update you if I
make any more progress.
