It's very unclear what the best course is.  I've heard that some devices
will crash if they are asked for less than the full device descriptor.  I
don't know how true that is, but I've seen at least one example of a
device that crashed when asked for 8 bytes instead of 9.

On the principle that vendors design their devices to work with Windows
and test them that way, the best thing to do is to imitate Windows.
Unfortunately, I don't know what Windows does when it encounters a
low-speed or a high-speed device.

Is there anyone out there with a bus analyzer who can try this and
report the results?

The answer is complicated. There is no "Windows" -- each version is slightly different. win98 did things differently than xp does. I enclose a couple of device enumerations from "XP home". I don't have access to a win98 machine until this weekend. You will notice that the older 1.0 device (8 byte control packets) was enumerated differently than the device that was for usb 2.0 (with 64 byte control packets).

These two dumps were processed (decoded) by an awk program from the original html capture. Even though there is a lot of extra junk in them, I think they show two complete enumerations.

The old 1.0 device was a "ZOOM" modem (acm compatible), the newer was some generic keychain flash device.

I am attaching the files in the hope that they will not become line-wrapped in this mailer...
