Don't present it as "supporting Linux".
Present it as: your device is blatantly NONconformant to the USB specs,
and absolutely *ANY* host is within its rights to refuse to talk to
your device on that basis. Host controllers are not even expected to
be able to talk with it!! Reference: USB 2.0 spec, section 5.8.3 in
paragraphs 1 and 3.
Customers may even have legal "false advertising" claims against this
vendor.
If the vendor is using the official USB markings on their device, they
would also be in trademark violation with the usb.org working group, a
body that takes these things very seriously.
I don't believe they do use the markings. The device is sold via their
web-site only (where I didn't notice the usb logo), and the one I have
access to doesn't show the USB markings anywhere. Anyway, I'll retract
my previous statement about their reluctance to help. The vendor said
their next firmware release would include a configuration with 512 byte
packets. they also gave me permission to both redistribute and modify
their firmware so I suppose if I had the time I could add support for
512 byte packets myself (though I've never played with the Ez-USB/FX2
before, and don't really have the time to learn at the moment).
